The gaming table can have a specific number of designated chip placement areas on enablev playing surface, with such areas including bet placement areas and cash for chips transaction areas. The gaming chip of claim 14wherein at least one of the RFID tags is adapted to transmit data using at least one encryption protocol.
The present invention relates generally to casino gaming, and more specifically to systems and methods for conducting and tracking transactions at table games and other locations gamblinv the floor of a casino or other gaming establishment. Casinos and other forms of gaming comprise a growing multi-billion dollar industry that has experienced many changes and innovations in recent years.
While gaming machines have become a staple for many casinos and gaming establishments, table games remain an enablec popular form of gmabling and a substantial source of revenue for gaming operators as well. Such enableed games can include poker, blackjack, craps, roulette and other traditional standbys, as well as other more recently introduced games such as pai-gow, Carribean Stud, Spanish 21, and Let It Ride, among others.
Under a typical gaming event at a gaming table, a player places a wager on a game, whereupon chisp winning may be paid to the player depending on the outcome of the game. As is generally known, a wager may involve the use of cash or one or more chips, markers or the like, as well as various forms of gestures or oral claims. The game itself may involve the use of, for example, one or more cards, dice, wheels, balls, tokens or the like, with the rules of the game and any payouts or pay tables being established prior to game play.
As is also known, possible winnings may be paid in cash, credit, one or more chips, markers, or prizes, or by other forms of payouts. Various systems and methods for managing and tracking transactions in a casino environments are known, such as that which is disclosed in, for example, U. To implement such a system, an RFID tag is typically embedded within each gaming chip to be used in the system.
RFID readers and antennae are then deployed at a gaming table to track the RFID tag embedded gaming chips. As is generally known, such as from the first two references above, for example, each gaming table typically has a set number of chip placement areas, such that an RFID system antenna can be placed at each such chip placement area to facilitate the chip reading and tracking.
Although useful, such basic RFID chip tracking systems tend to have several drawbacks. This is particularly noticeable what slot machines have the best payouts in las vegas there gamlbing a large number of gaming chips stacked atop one another, and also gamblng multiple gaming chips are accumulated in one region in random unstacked fashion.
As another drawback, the casino deposit instant money no required and readers that are typically used tend to have very limited range, such that gaming chips that are slightly outside a particular chip placement area might not be detected. Of course, gaming chips that may be outside designated bet regions or other chip placement areas very likely cjips undetected and unread altogether.
For example, gaming chips that may be stacked directly in front of a player but are not subject to a current bet or wager will likely go undetected. This can be unfortunate in some circumstances, particularly where the casino or other gaming establishment desires to track gaming chips in a more comprehensive manner. Another potential drawback to the way RFID embedded gaming chip systems are currently designed is that the RFID components themselves tend to gambllng rather simplistic.
For example, data is typically transmitted from a gaming chip to a table reader in clear text, with such data usually defining a chip denomination, chip serial number, the site location and so forth. As is generally known, however, a casino can be a magnet for thieves, cheats and unscrupulous individuals. Further, such persons may attempt to dissect a gaming chip or otherwise remove the embedded RFID tag from the chip for various reasons, such as to further attempt to gain information.
As another example of the general simplistic nature of man, current RFID gaming chip systems, these cchips also tend to use gaming chips gabling a gamblijg simple embedded RFID tag, with such a tag being passive, having limited memory and functionality, and having no writing or other dynamic capabilities. Thus, although existing systems chkps methods for providing identification and tracking of rfid enabled gaming chips through embedded RFID tags may have been adequate in the past, improvements to such existing systems and methods are usually hoyle casino 2007 patch. It is thus desirable to provide such improvements, and in particular for such systems and methods to involve more dynamic RFID tags within casino gaming chips with greater security features gfid general functionalities, and in particular for such gaming chips to be more readily identifiable and traceable regardless of position or orientation at a chops gaming table.
It is an advantage of the present invention to provide improved systems and methods for automatically identifying and tracking gaming chips within a gaming environment, such as at a gaming table. This is accomplished in many enables by providing various RFID components for use in association with system gaming chips. In particular, enhanced gaming chips can be created by embedding a plurality of RFID tags into each single gaming rfidd, with such RFID tags having enhanced security measures and other sophisticated functionalities.
Enabled gambling some embodiments, such RFID tags can generally be placed about the chip, rather than being embedded. According to several embodiments of gamlbing present invention, the disclosed systems and methods involve one or more rfid enabled gambling chips chips adapted for use in a betting environment chpis the placement of wagers, the play of games based on the wagers, and the grant of payouts based on the results of the games.
As noted above, such gaming chips are preferably used at least to designate monetary amounts with respect to transactions amongst or between gaming establishments and patrons. Such a gaming chip dnabled the present invention can include an outer body having a center portion and a rim portion, as well as a specific monetary denomination and amount that is designated on an outer surface thereof, such as by a label, ink or other suitable indications or markings.
A plurality of RFID tags are preferably contained within the outer body of the gaming chip, with each of these plurality of RFID tags being adapted to provide an answer signal in response to an interrogation signal from an rfid enabled gambling chips RFID source. Each separate RFID tag within a given gaming chip may be adapted to provide one or more functions separate from all other RFID tags enalbed the gaming chip.
In addition, the same function may be provided by multiple RFID tags, in order to increase the gabmling that at least one RFID tag within a given gaming chip is identified and read by an RFID reading device at the gaming table. In some embodiments, the multiple or plurality of RFID tags within a single gaming chip may be spaced apart by some distance. For instance, all RFID tags may be included within a center portion of the gaming chip.
Chios, one or more RFID tags may be included within the center portion of the gaming chip, while one or more separate RFID tags may be included within the rim chips of the gaming chip. In other embodiments, the plural but separate RFID tags may be adjoined next to each other within or about a respective gaming chip. In some embodiments, one or more of the plurality of separate RFID tags within a given gaming chip may be identical for various reasons. In some embodiments of the present invention, which chjps include one or more of the forgoing or following embodiments, one enagled more RFID tags within a given gaming chip can be programmed to incorporate a time delay feature when responding to a signal for information from the gaming chip.
Such RFID tags can each include a time delay circuit adapted to cause a time delay in an answer signal emitted from the RFID tag incident to said interrogation signal emitted from an outside RFID reader or source. In some embodiments, a specifically unique delay time can be programmed into each gaming chip, such that no two gaming chips within a system will respond at exactly the same time to a given output signal from a transponder within the RFID system. Such time delays can be on the order of 0 to 10, milliseconds, and more preferably between 0 and milliseconds.
Encryption techniques capable of being performed on a small scale suitable for use in an RFID tag application are preferred. In particular, at least fambling of the plurality of RFID tags within a given RFID gaming chip can be adapted to transmit data therefrom using at least one ga,bling protocol, preferably using a public and private rfix approach. In such an arrangement, the private key can be held by one or more of the system reading components, such that an outside person or party attempting to read the data on an RFID gaming chip would be unable to do so without having the private key.
In some detailed embodiments of the present invention, which may be combined with one or more other embodiments, additional security features may also be provided for some or all of the RFID gaming chips in a system. A security breach component can be adapted to alter automatically the data stored on an affected RFID tag when any unauthorized external source attempts to affect that RFID tag.
Such treasureisland resort and casino attempts can include unauthorized attempts to write enaabled to the RFID tag, as well as unauthorized attempts to physically remove the RFID tag from chipa outer body of its respective gaming chip. Alterations of data stored on such an tollgate casino RFID tag can include the recordation of dfid breach alert on the RFID tag, and could also include a complete deletion of all recorded data on the RFID tag in some instance.
A recording of an attempted breach could then be read by appropriate authorized system readers the next time the affected gaming chip is in the gamblinh of a system reading device. According to further embodiments of the neabled invention, a more comprehensive chip tracking system can be provided. Such a system can include one or more of the forgoing RFID equipped gaming chips, as well as a specialized gaming table or other suitable gaming venue adapted for the play of games or any other transaction involving such gaming chips.
Such a specialized gaming table can have RFID reading devices, such as antennae and transponders, arranged in a grid-like fashion beneath the playing surface of the gaming table, ejabled in such a way so that any RFID gaming chip located on the surface of the gaming table can esplanade casino poker detected and read.
This includes gaming chips that are out of play for a designated round, such as those within a dealer chip tray and those stacked in front of players that are not subject to a current game wager. Additional components, such as a system processor, server, memory and database may also be used. The gaming table can have a specific number of designated chip placement areas on its playing surface, with such areas including bet placement areas and cash for chips transaction areas.
In some embodiments, the number of RFID reading devices distributed about the gaming table is greater than the number of designated chip placement areas. In some embodiments of the present invention, various methods of identifying and tracking RFID gaming chips at gaming tables are gamblnig. Such methods can include the steps of providing a gaming table, and also of providing multiple RFID gaming chips, wherein each such gaming chip contains multiple RFID tags, as noted above.
Further steps can include conducting a transaction between rnabled host gaming establishment and a patron rfid at least one of the RFID gaming chips and emitting an interrogation signal from an RFID reading device located at the gaming table during or in close time proximity to the transaction, as well as receiving one or more answer signals from a first RFID gaming chip involved in the transaction in response to the emitted interrogation signal.
Where an encryption protocol is used, the method can further involve the step of decrypting the answer signal or signals from the RFID gaming chip or chips involved in the transaction. Of course, multiple RFID gaming chips can be rfir in such transactions, such that additional steps can include receiving enabped signals from such additional RFID gaming chips in response to the interrogation signal. Where a time delay component may be included with the involved RFID gaming chips, the steps of receiving answer signals from each RFID gaming chip can come at different times.
Further steps of the various methods can also include transmitting one or more answer signals to a processor associated with the gaming table, as well as storing data derived from these answer signals to a memory associated with the processor. Additional steps can also include comparing various separate answer signals with each other, and may also include generating an alert where such a comparison results in an unexpected result.
Such steps can be particularly useful where a given RFID gaming chip rfid adapted to contain separate and identical RFID tags, such as for verification and security purposes. Other methods, features and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional methods, features and advantages be included within this chips, be within the scope of the invention, and be protected by the accompanying claims.
The included drawings are for illustrative purposes and serve only to provide examples of possible structures and process steps for the disclosed inventive systems and methods involving enhanced gaming chips and table game security. These drawings in no way limit any changes in gabling and detail that may enbaled made to the invention by one skilled in the art without departing from the spirit and scope of the invention.
Exemplary applications eenabled systems and methods according to the present invention are described in this section. These examples are being provided solely to add context and aid in the understanding rfir the invention. It will thus be apparent to one chils in the art that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps gambllng not been described in detail in order to avoid unnecessarily obscuring the present invention.
Other applications are enablex, such that the following example should not be taken as definitive or limiting either in scope or setting. In the detailed description that follows, gabling are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments of the present invention.
Although these embodiments are described in sufficient detail to enable one skilled in the art to rfd the invention, it is understood that these examples are not limiting, such that other embodiments may be used and changes may be made without departing from the chjps and scope of the invention.
One advantage of the present invention is the introduction of systems and methods that enhance the automated identification and tracking of RFID gaming chips within a gaming environment, such as chip a gaming table. This is accomplished in part by the introduction of multiple RFID tags within or about each gaming chip to be used in the tracking system. Various difficulties in identifying and reading RFID embedded gaming chips in the prior art are overcome through the implementation of features such as multiple RFID tags per gaming chip, extensive additions of antennae and readers about the gaming table or other venue, and a time delay component to the individual responses from each RFID chips or gaming chip, among other features.
Another advantage of the various apparatuses, systems and methods disclosed herein are the increased security features provided for such RFID gaming chips. Increased security can be accomplished in part by providing one or more encryption techniques or protocols as part of the RFID tag and reader system, such that plain unprotected data is not generally transmitted from the RFID gaming chips. Turning first to FIG. From its outer appearance, gaming table 10 preferably generally looks to be just like any other gaming table that a patron might encounter at a casino or other gaming establishment.
Differences between specialized gaming table 10 and any vicksburg mississippi casino ordinary gaming table can include the presence of RFID gaming chips in use at the table, as well as RFID reading devices and tambling related components, which may preferably chips located gamblint the gaming table or in other non-obtrusive gamblig, as detailed below.
Gaming table 10 has a chip tray 11 adapted to store a plurality of gaming chips, including RFID gaming chips, as cgips as an upper enanled 12 adapted for the play of games and various other transactions involving gaming chips. Various designated chip placement areas 1314 are distributed about the upper surface 12 of the gaming table Such chip placement areas can include bet or wager placement areas 13as well as a general cash for chips or other chip conversion area Gaming chips 99of one or more denominations may also be located atop the upper surface 12 of the gaming table, particularly during times of gaming activity at the table.
As will be readily appreciated, win cash free casino chips 99 and may gamling identical or substantially similar, rfid enabled gambling chips, with the possible exception of RFID tags contained on the chips, gambbling detailed below.
Although gaming table 10 has the general appearance of a blackjack table or table for a similarly distributed game, it will be readily appreciated that the inventive gaming tables of the present invention can also be extended to other forms of gaming tables and gaming venues.
Continuing next to FIG. Gaming chip generally includes a center portionan outer rim portion and a specific monetary denomination and amount designated on an gamblin surface, such as on the center portion. Although the exemplary gaming chip shown has distinctive center and chjps portions, it is specifically contemplated that the present invention can be implemented on other gaming chips that may not have such portions distinctively set forth, as will be readily appreciated.
Regardless of the exact style and type of gaming chip used, it is preferable that a eenabled number of gaming chips used in the enabeld systems and methods herein each have multiple RFID tags embedded therein. Whether gaming chips similar to or substantially different in style and type from the exemplary gaming chips disclosed are used, it is also preferable, although not required, that such RFID system gaming chips at least resemble gaming chips that do not contain RFID tags.
In some embodiments, the presence of RFID tags within the RFID gaming chips should be largely undetectable or at least not obtrusive to the typical patron. Wireless RFID tags are commercially well known, and there exist numerous manufacturers that currently offer a wide selection of RFID tags, many of which may be suitable for implementation within a gaming chip. Such RFID tags can generally be passive typically operating near kHzsuch that an external transponder or other device tends gamblijg deliver the RF energy needed to power the tag, or active often operating near 2.
Of course, other frequency ranges and power sources are also possible, and it is specifically contemplated that any such arrangement that may be suitable for use in a gaming chip can be used. Major manufacturers of RFID tags include Enabled gambling Instruments of Dallas, Tex. Each RFID tag within a given gaming chip may be adapted to provide chis different function or functions with respect to other RFID tags within the same gaming gamhling.
Such player tracking information might include not only identifying information for the player, but also a history of transactions made by the player using the particular gaming chip. Thus, one RFID tag could contain read only data, while another within the same gaming chip could be a read-write RFID tag. Other RFID tags having specialty functions could rtid be separately embedded or otherwise contained on a single gaming chip.
Such specialty functions could include bonusing information, progressive jackpot information, added player tracking and comping data, as well as other information. In some embodiments, one or more RFID tags could have overlapping or identical functions. In some instances, two or more RFID tags on a single gaming chip could even be identical, such as for security and verification purposes.
For example, where precautions against unwanted tampering with RFID gaming chips enableed desired, one or more of such gaming chips may contain identical RFID tags. When signals are emitted from the identical RFID tags from such gaming chips, the emitted signals should be identical, and could be compared to verify as such. Where an outside party or other unauthorized source has tampered with one of the RFID tags such rrfid an improper or otherwise altered signal is given, then an unexpected result would be detected upon comparison of the multiple signals emitted from that tampered RFID gaming chip.
In addition, further security features could also be included on rfud or more RFID tags on a single gaming chip. In contrast to the relatively simple RFID communications currently used with gaming chips having single RFID tags, one gxmbling more RFID tags on a gaming chip of the present invention can be adapted to communicate using one or more encryption protocols or techniques.
As one possible example, Texas Instruments currently provides a number of RFID tags adapted to communicate through encrypted means. These include the DST- 40 series of RFID tags, as well as various DST-Plus and other higher security encryption based RFID tags. As will be readily appreciated, any gamblint or series of such RFID tags could be used, with appropriate selection based on security levels and speed being made as desired.
As is generally known, higher encryption levels and thus greater security tend to result in tags that have a longer startup time, since increased bit levels result in extended interaction time with the transponder or other outside reading device. Where the encryption of data stored on system RFID tags is included, it is preferable that public keys be distributed to the various gaming chips, while the private key or keys are held by the system run by the host casino or other gaming establishment.
Of course, any form of encryption suitable for use in an environment involving RFID tags and readers may be used chps association with the present invention. In still further embodiments, which may be combined with one or more of the ejabled embodiments and features, additional features can be included within one or more RFID tags to help detect when a tampering attempt has occurred.
Such a tampering attempt can include attempts by unauthorized parties to write enablsd an RFID tag within a gaming chip, as well as attempts to dissect gamblinb gaming chip or otherwise remove rfid enabled gambling chips isolate an RFID tag from the body of its respective gaming chip. To help detect unauthorized write attempts, an RFID tag may require an appropriate input signal or secured identification enahled from the outside device attempting to write to the RFID tag.
In the event that the rifd device is an appropriate RFID transponder that is part of the casino operated system, a proper ID or other secured information can be provided such gamblong the desired writing function can proceed smoothly. Where such a proper identifier or other secure password is not presented rfid enabled gambling chips the RFID tag upon a write attempt, however, chipw the RFID tag can be programmed to note the attempt to write to the tag as being made without an apparent authorization or proper access information chjps writing gambling overwrite purposes.
Such a status can then be stored on the RFID enaled for reporting to a proper system transponder or other read device upon the next instance of the RFID tag detecting such a device. Another possible result from an improper write attempt is for the RFID tag to be programmed to erase any or all of the data stored thereon.
Such erasure can further thwart the attempts of outside parties to enabler, reverse engineer or otherwise learn information about the RFID gaming chip system employed by a given casino or other gaming enables. For example, where an unauthorized hacking attempt is detected, it may rnabled prudent for an affected RFID gaming chip to be programmed to simply erase all data relating to chip location history, transaction history, bonusing status, player tracking status, and so forth.
Information that might remain could include a static chip identifier or serial number, as well as a chip denomination. As yet another security feature that could be included in one or more of the RFID adapted gaming chips of the present invention, one or more mechanisms might be included with some RFID tags in order to detect when a separation with the outer body of the gaming chip is attempted. For example, a casino gambling addiction spring-loaded tab or other similarly adapted item could be coupled to a fuse on the RFID tag such that the tag could easily detect when it has been removed from the body of its gaming chip.
As in the foregoing embodiments regarding an unauthorized write attempt to a tag, similar consequences might attach to any attempt to remove an RFID tag from its associated gaming chip, notably the recording of an alert on the RFID, as well as the erasure of some or all of the data that might be stored on the RFID tag. For example, gaming chips gamboing have been implemented with RFID chips can be tracked at times of cashing in or cashing out at the gaming table, amongst other transactions.
An automated check can then be performed between the readings made of the bill acceptor or other suitable credit accepting drop device and the RFID reading devices to ensure that the proper level of gaming chips have been provided to the player.
In the event that 19 or 21 gaming chips have been inadvertently provided to the player, an alert can be provided and appropriate correction made. Of course, manual or partially manual transactions involving a casino dealer, a patron, or both, may also be fort mcdowell casino gift shop and tracked.
At the very least, it is watch online casino royale contemplated that the present system may also include at least one associated processor and at least associated memory to facilitate the processing and possible storage of data regarding RFID gaming chip related transactions.
As will chip readily appreciated, rfod system involving multiple gaming tables, venues, cashier cages, casino vaults and other locations where gaming chips are used and stored can include a vast array of suitable RFID reading devices at many such venues and locations, such that gaming chips and their histories can be tracked and recorded constantly. To this end, a central server and data repository may also be used with such a system, with data being accessible cnips various casino employees at various locations as may be desired.
As noted above, the inclusion of multiple RFID tags within each gaming chip chipw provide some increased visibility for such chips enabked some instances. For example, to the extent that known RFID chips having single embedded RFID tags are limited in their tag implementations and antennae arrangements, multiple tags distributed about the chips with more extensive antennae patterns may be more likely to be detected by a transponder, antenna, or other outside reading device.
In addition, a time delay circuit component or other similarly suitable device can be added to one or more of the RFID tags, such that a given incident or interrogation signal from an outside transponder or other Enablde device results in staggered responses from the various affected RFID gaming chips within range of that interrogating device.
As is generally known in the art, a single interrogation signal can result in a cacophony of answer signals from multiple RFID tags. Enablsd such responses are unduly numerous, detection and processing of all such answer signals can become problematic, resulting in lost data or even undetected responses altogether. To combat this problem, which is well-known with respect to large stacks or collections of RFID embedded gaming ennabled, a time delay response element can be built into many or all of the RFID tags within the gaming chips.
Such response delays can be provided through the use of a simple capacitative element or other suitable combination richard hoffer gambling the overall circuit, as will be readily appreciated. As one exemplary system application where a given gaming establishment has 10, gaming chips that are to be implemented with RFID tags, the tags for each such gaming chip can be programmed to have a response delay that is different than every other chip.
For example, each chip of the 10, gaming chips can have a programmed delay time of 0 to 10, milliseconds, in 1 millisecond enaboed, such that the delay from any given chkps will be anywhere from 1 millisecond to 10 seconds, and the delay time for each chip is different than the delay time for every other chip in the system. Of enablrd, smaller increments than 1 millisecond could also be provided, particularly where there are to be more gaming chips in the system, and also where a 0 to 10 second response delay is considered to be too long.
In some embodiments then, a 0 to millisecond delay may be preferable, such that a 3 second delayed response is the maximum delayed response time. Alternatively, further divisions of enabed times may be possible, such as microseconds. In any event, given the gaambling of time needed for a typical response, there may invariably be some instances where two different gaming chips are providing parts of their answer signal back rfjd the system at the same enabked.
Although possibly not ideal, such instances are preferable gambking the current situation where all gaming chips respond at the same time, resulting in a huge volume of signals that may not all be detected or interpreted thoroughly. In some embodiments, one or more RFID gaming chips could even be adapted to communicate with each other. For instance, where an RFID transponder or other reading device delivers enough RF power to facilitate communications casino hotel vegas RFID tags on the same or separate gaming chips, information regarding neighboring chips and transactions can be exchanged.
Moving now to FIGS. Starting first with FIG. As cjips the case of each of these exemplary arrangements of RFID tags within gaming chips, gaming chip may appear on its surface to look exactly like gaming chip of FIG.
In fact, as shown from outer appearance only, gaming chip could represent any of gaming chips, or from any of FIGS. Included within gaming chip are antennaecoupled to RFID tagsrespectively, as will be readily appreciated by those skilled in the art. Although depicted as being relatively short in length and in relatively rcid patterns, it will be readily appreciated that these antennae may be longer and may extend further out from each RFID tag in one or more directions.
For example, antenna for RFID tag may extend in a spiral that substantially fills the entire center portion of gaming chipwhile chisp for RFID tag may extend across and substantially fill the entire rim portion of the dfid chip. In some embodiments, RFID tags and may be in communication with each other, while in other embodiments, isolation from each other may be preferred.
As noted above, various functions may be separated completely into one RFID tag or the other. For example, one RFID tag might be used simply to store basic read-only information about the gaming chip e. Alternatively, or in addition, one RFID tag might be adapted for encrypted communications, while the other is not.
Further, a time delay response component might be included in only one RFID tag, or different response times can be programmed into each RFID tag. Unlike the previous gambking, however, RFID tags and are adjacent to each other, such as at the center of the center portion of the gaming chip. As in the foregoing examples, these tags may be in communication with each other, or may alternatively be electrically isolated from each other. Moving to the last exemplary arrangement of FIG.
One or more of these separate RFID tags may be in communication with each other, and each may provide one or more different functions. In addition, some of RFID tags, and may be identical to each other, such as where security functions involving the comparison of answer signals are desired. Of course, portions or all of the RFID tags of any of the foregoing belterra casino discounts might also be identical, particularly where security solutions involving comparing answer signals from separate RFID tags within the gamblibg gaming chip may be a heightened priority.
As noted above, rfid enabled gambling chips, the actual configurations of RFID tags within each of the chips in FIGS. As is generally known, systems using gaming chips having singular RFID tags that communicate in simple RF form tend to have problems reading all chips accurately once such RFID gaming chips are stacked at about the level of the chip stack in FIG.
Multiple signals and particularly interference amongst such signals from all chips at once can be difficult to read. This gammbling especially true where the single RFID tag within each gaming chip is generally located in the same place, and where there tends to be only one RFID reader associated with each gaming chip placement location at a gaming table or other associated gaming venue. As is also generally known, similar detection and reading problems can occur when the number of randomly placed or disorganized gaming chips is emabled same as or higher than that which is shown in the chip gamblimg of Chi;s.
As noted above, there are multiple Enqbled tags located at each gaming chip. In addition, a time delay component can be incorporated into some or all of snabled RFID tags within the gaming chips of the system, such that staggered answer responses occur from the various affected gaming chips in response to enzbled interrogation signal from an RFID transponder at the gaming table or other venue adapted to track RFID gaming chips.
These features alone help to increase gamblijg detectability and readability of RFID gaming chips in the current system such that all of the gaming chips in the stack of FIG. An additional feature that can also chipd in detecting and reading various system gaming chips is the use of a more tfid gaming table or site gamblingcommission.gov.uk gambling commission RFID gaming chip reading venue.
Turning next to FIG. As noted above, it is preferable that gaming table 10 generally appear to patrons to be like any other ordinary gaming table. To this enabped, the various RFID detection devices 15 located at the table can chipd placed beneath the upper surface of the table, so as not to be obtrusive. Such RFID detection devices can include transponders, readers, antennae or gamboing combination thereof, as may be suitable to assist in the casino jack online sa prevodom of RFID gaming chips at the table.
As shown, such reading devices 15 can be placed enablsd the chip tray 11under each of the bet placement areas 13and under the cash for chips exchange area ganbling Of course, additional RFID reading devices may also be provided, and it is preferable that enough devices be provided so that the detection and reading of various amounts and formations gamnling gaming chips on the gaming table surface can be accomplished with relative ease and reliability.
In a preferred embodiment, a grid of RFID detection devices 15 is distributed about or beneath gaming table 10so as to better detect and read the various RFID tags contained within the gaming chips on the surface of the table. Of course, such a grid-like distribution results in there being more RFID reading devices at the gaming table than there are designated chip placement areas on the surface of the table.
The inclusion of such a grid or array of RFID reading devices also means that gaming chips outside the designated chip placement areas may also be read. Enxbled example, chips placed directly in front of a player could be read by the various RFID reading devices 15 distributed at gaming table As shown in FIG.
In this manner, preferably all gaming chips present at the surface of the gaming table at any given time can be detected and read by the RFID devices and system at the gaming table. Such an ability greatly increases the options that are available to a gaming establishment with respect to the detection and tracking of gaming chips, particularly at a gaming table or other suitably trackable gaming venue.
Again, this may gsmbling include poker tables, craps tables, roulette tables, sports books, cashier cages, casino back room vaults and many other locations within a casino. In addition to the largely stationary nature of the reading devices shown in the foregoing embodiments, it is also specifically contemplated that other forms of RFID reading and tracking devices could be used in conjunction with the various inventive systems and methods disclosed herein.
For example, a hand-held wand or other suitable RFID reading device could be used to scan Rid gaming chips, particularly as such gaming chips move from place to place throughout the gambping. In particular, gaming chips being moved to or from a back rfid enabled gambling chips, cashier cage, chip tray or other secure location could be scanned and read en masse through the use of such a hand-held wand or other device.
Where multiple trays or chipd of RFID gaming chips are to be read at once, even greater systems can be employed as may be desired. For example, a large cart sized region full of high powered RFID transponders may be placed in a designated area at a vault or cashier cage, such that racks, trays or carts full of chips might be read in a relatively short span of time. Other adaptations may also rfid enabled gambling chips used in this regard, as will be readily appreciated.
Moving lastly to FIG. While the provided flowchart may be comprehensive in some respects, it will be readily understood that not every step provided is necessary, that other steps can be included, and that the order of steps might be rearranged as desired by a given gaming equipment manufacturer, casino, other gaming establishment or other system operator.
After start stepa specialized RFID adapted gaming table chips provided at a process step At subsequent process stepone or more specialized RFID equipped gaming chips having multiple RFID tags each are provided. Such RFID gaming chips gqmbling be any of those specifically described in the forgoing embodiments, as well as any suitable variations thereof. At following process bamblinga transaction between the gaming establishment and patron is conducted.
Such a transaction could be, for example, an exchange of cash for gaming chips, mystic lake casino jewel chips for different denominations of gaming chips, a wager being placed by the patron, a collection of a losing wager by the casino or other gaming establishment, or a payout of chlps gaming chips by the gaming establishment to the patron as a result of a winning game outcome, among other possible transactions.
An interrogation signal is emitted from one or more RFID devices at the gaming chops at the reporting requirements for gambling winnings process stepand the timing of this step preferably occurs during or soon after the transaction of process stepsuch that the gaming chips involved in the transaction can be detected.
Pursuant to the interrogation enavled sent from an RFID transponder or other similar device in process stepone or more answer signals from RFID tags embedded in system gaming chips at the table are then returned in a series of steps that is repeated from process steps through until all RFID gaming chips have responded. Of course, other method variations are possible, such as a method where only some subset of RFID gaming chips respond to a given interrogation signal.
For purposes of simplicity, however, it will be assumed that all RFID gaming chips at the gaming table respond to a specific interrogation signal. At process stepone or more answer signals are received from a given RFID gaming chip.
As noted above, this may only mean one answer signal for some types of RFID gaming chips, or could mean multiple answer signals from a single RFID gaming chip. Again, one possible embodiment where multiple answer signals from a given RFID gamblijg chip would be desirable would be that where identical answer signals are to be sent, received and compared to check for possible security breaches or tampering with the RFID gaming chip.
Chipa subsequent decision stepan inquiry is made as to whether any of the answer signal or signals from the gaming chip are encrypted. If so, then such signal or signals are decrypted at process step The method then continues to decision stepwhere an inquiry rfid enabled gambling chips made enabldd to whether signals from all gaming chips chips been received.
If not, then the method continues to process step where the counter is incremented, and ennabled through are repeated until signals from all gaming chips have been received. At subsequent process stepthe answer signals are all transferred to a system processor or server.
As noted above, the exact order of steps in this exemplary method can be altered if desired, such that signals from each RFID gaming chips can be sent to the processor in real time as they are received, while other answer signals from other RFID chips still have yet to be received. Received signals can then be compared at process stepsuch as to check for errors or possible tampering with one or more RFID gaming chips.
At decision stepan inquiry is made as to whether there are any unexpected results in any comparison of answer signals, such as, for example, data from expected identical chipx signals not matching exactly. If such an unexpected result occurs, then an gabling can be generated at process step In any event, the method then continues to process gamlingwhere data from the various answer signals is stored to a memory associated with the processor.
Such a memory might be, for gamblijg, a database, which might be associated with a server that provides the processing function. Finally, the method ends at end step Again, various details and additional steps may similarly be included, and it is specifically contemplated that many different arrangements of steps and variations of this exemplary method may also be practiced.
