Abstract:
An intelligent casino chip method. A method for promoting play of a live casino card game during a scheduled time event. A special casino chip is provided to a player in which a promotion is encoded into the transponder found within the casino chip. When this casino chip is placed by the player on the live casino card game, a computer system reads the promotion from the transponder and determines whether the scheduled time event exists in response to reading. If the scheduled time event exists, the player participates in the promotion.

RELATED APPLICATION 
     This application is a continuation of U.S. patent application Ser. No. 09/767,654 filed on Jan. 22, 2001, now U.S. Pat. No. 6,464,584 which is a continuation of U.S. patent application Ser. No. 09/167,847 filed Oct. 7, 1998, now U.S. Pat. No. 6,186,895, which claims the benefit of U.S. Provisional Application Serial No. 60/061,297 filed Oct. 7, 1997. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to casino chips containing implanted computer-based transponders. 
     2. Statement of the Problem 
     A need exists to provide an intelligent casino chip system which allows a casino to accept and recognize a separate incremental wager on an existing betting position. 
     Conventionally, the casino advantage on card games such as blackjack amounts only to 1.5% to 2.0% and does not allow sufficient margin to fund bonuses or progressives that offer attractive pay outs. In contrast to conventional slot machines such as the popular $1.00 slot machine, such slot machines will generate more than twice the revenue per hour of play than a blackjack position at less than half the operating cost. 
     Conventional game variations on live card games have utilized the concept of an additional, incremental, bet in order to fund a bonus jackpot such as found in CARRIBEAN STUD or TWENTY-ONE MADNESS. In U.S. patent application Ser. No. 08/602,074 (McCrea), an invention pertaining to the use of a single game bet or wager for playing both a live card game and a progressive game is set forth. 
     Gaming chips with electronic circuits have been used in the past, including the following:

     U.S. Pat. No. 5,651,548 (Jul. 29, 1997) discloses gaming chips with electronic circuits that are scanned by antennas in gaming chip placement areas. The chips transmit information such as individual identification numbers which identify the particular chip and the value of the chip. The system includes an electronic system for receiving and storing the information from the antennas so that the location of the gaming chips can be tracked. 
     U.S. Pat. No. 5,166,502 (Nov. 24, 1992) discloses a fabrication process and the resulting gaming chip which utilizes an implanted electronic circuit encoded with identification information, which may include, but is not limited to, casino designation, chip value, serial number, and date of issue. The chip contains a programmable 32-bit transponder. In use, the transponder is electrically simulated by a reading device which causes the transponder to transmit the information stored in it. The encoded information which is read may then be processed by a computer or similar device. A computer program matches the encoded information with information stored in its data base and then decodes and outputs the information in a legible manner for immediate or later review. 
     U.S. Pat. No. 3,766,452 (Oct. 16, 1973) teaches a thin passive RLC resonant circuit embedded in the periphery of a chip or token. A signal generator and antenna are used to transmit a preselected frequency or narrow band of frequencies in which the resonant frequency of the chip falls. A receiver and antenna which are tuned to the preselected frequency or range of frequencies are placed across from the transmitter and antenna. When a chip or token containing the resonant circuit passes in front of the transmitting antenna, a tinging or sustained oscillation is produced in the chip which is detected by the receiver. 
     U.S. Pat. No. 5,361,885 (Nov. 8, 1994) teaches an anti-counterfeiting device for use with gaming chips. The device contains a special interchip formed of light-conducting material which is embedded in plastic gaming chips during fabrication. The interchip forms a plurality of fingers, each of which terminates and presents a lighted face at the edge of the chip. When light is shined on one of the faces of the interchip, it illuminates all of the interchip faces distributed along the edge of the chip. The number of faces can then be counted and used as an identifier of the type or dollar amount of the chip. 
     U.S. Pat. No. 5,406,264 (Apr. 11, 1995) discloses a gaming chip which contains an amorphous magnetic marker material which allows the gaming chip to be detectable by low frequency electronic article surveillance system. 
     SUMMARY OF THE INVENTION 
     1. Solution to the Problem. The present invention solves the above-stated problem by providing an intelligent casino chip system, and method for using the system, that differentiates between two classes of gaming chips intermingled within a single discrete betting area. 
     2. Summary. An intelligent casino chip system having a gaming table with at least one discrete player area is disclosed. Each player area has a discrete betting area for receiving gaming chips. Two classes of gaming chips are used. The gaming chip of the first class has a first transponder containing at least value information. The gaming chip of the second class has a second transponder containing value and class information. A primary game wager, containing gaming chips of the first class, is placed as a stack in the discrete betting area intermingled with a secondary game wager comprised of at least one second class gaming chip. A transceiver system is positioned on or near the gaming table so that it is within the vicinity of the betting area. The transceiver receives signals from the respective transponders. Hence, value signals are received from the first transponder and value and class signals are received from the second transponder. Each of these signals are conveyed to a computer system that then determines a primary wager value of the primary wager based only on the value signals received from the first transponder, and the secondary wager value of the secondary wager based on the value and class signals from the second transponder. These respective wager values can be combined or maintained separately for progressive gaming, player identification, etc. In any case, the computer system differentiates the secondary wager from the primary wager based on the different signals from the respective transponders. Thus, the computer is able to differentiate and value the separate (primary and secondary) wagers when the primary and secondary wagers are intermingled in a single stack in a single discrete betting area. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     The present invention can be more readily understood in conjunction with the accompanying drawings, in which: 
     FIG. 1 shows a top view of a gaming table having player areas and betting areas. 
     FIG. 2 is a cross-sectional view of the gaming table through the bet area, taken along lines  2 — 2  in FIG.  1 . 
     FIG. 3 shows a memory in the transponder of a special chip. 
     FIG. 4 shows a scheduled event. 
     FIG. 5 shows a number of game tables interconnected to a controller over a network. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     In FIG. 1 is set forth the top view of a gaming table  10  having a discrete player&#39;s area  20  and a discrete betting area  30 . Any number of player positions  20  could be located on table  10 . Furthermore, the shape of the player area  20  and the shape and location of the betting area  30  can be of any suitable design and location. 
     In FIG. 2, a cross-section of the table  10  taken along line  2 — 2  in FIG.  1  through the bet area  30  is shown. Placed in the betting area  30  by a player P sitting at the gaming table  10  is a bet  200  which comprises five intermingled casino chips of two types,  210  and  220 . The bet  200  is shown to be in a stack but any suitable grouping of casino chips such as several stacks, individual chip placements, etc. could be provided and are equivalent. In each casino chip is an embedded transponder  230 . The transponder  230  can be either active or passive. Located in a vicinity near the bet  200  is a transceiver system  240  for transmitting and for receiving signals  255  from each transponder  230 . The term “vicinity” includes, but is not limited to, an area beneath the table  10 , actually installed within the table  10 , or above the table  10 . The functional requirement is that the transceiver system  240  through use of electromagnetic waves  255  is able to receive and read information from each transponder  230  in each type of chip  210  or  220  so as to obtain at least the value of the chip. The transceiver  240  delivers this information to a computer system  250  which is capable of determining the value of the wager  200  placed by a player P at the player&#39;s playing area  20  in the betting area  30 . 
     All of the above is conventional, except for the provision of a second class of chip  220 . Chip  220  is a specially programmed chip. The chip  220  may have either a game denominational or a non-denominational value. A denominational value can be, for example, $1,000, $100, $20, $10, and $1. A non-denominational value can be for promotional purposes whereby a player could win a promotional prize such as free meals, free accommodations, cash prizes, trips, or merchandise. 
     In FIG. 3 is shown a memory  300  in the transponder  230  of special chip  220 . Memory  300  has a data field  310  carrying an encrypted ID. This encrypted ID  310  identifies this chip as being of the second class  220  of casino chips and different from the class  210 . 
     Hence, when the computer system  250  activates the transceiver  240  to ascertain the contents of bet  200 , it will identify chips  210  of the first conventional class of gaming chips and retrieve the denominational value and identity code for each chip and it will recognize chip  220  as being of the second classification. Hence, the computer system  250  readily identifies casino chip  220  as a chip of the second type. 
     In one embodiment, the encrypted ID  310  stored in memory  300  of the transponder  230  in special chip  220  is used to identify chip  220  as a progressive wager. Hence, in a live card game  40  when a player P places the bet  200 , the progressive bet chip  220  can be intermingled in the stack without regard to ordering or separation. Hence, effectively multiple wagers are placed in a single stack and are read by a single transceiver  240 . The computer system  250  through use of the transceiver  240  precisely segregates chips  210  and  220  into separate classifications. Hence, the denominational value in chip  220  as read can be used as the bet for the progressive game. This is an important feature of the present invention since it eliminates a separate progressive bet area and separate progressive bet readers such as a chip reader, coin-in mechanism, etc. Under the teachings of the present invention, both the live card game wager and the progressive wager are placed in the same betting area  30  and the transceiver  240  under control of the computer system  250  ascertains the existence and value of the separate progressive bet. Any number of chips  220 , and hence wagers, can be in bet  200 . 
     Under a second embodiment, the encrypted ID  310  simply identifies the player P when placing a bet  200  in betting area  30  and the bet  200  can be used for both the live card game and the progressive game. This is similar to the approach set forth in U.S. patent application Ser. No. 08/602,074 (McCrea). This represents an improvement over the McCrea approach in that the player P makes a decision whether or not to participate in the live card game and the progressive game or to simply participate in the live card game. The special chip  220  simply identifies the player&#39;s bet  200  as qualifying for both the live card game and the progressive game. 
     The use of the special casino chip  220  encrypted as shown in FIG. 3 allows a casino to easily interface each particular gaming table  10  to either a bonus, a promotion, or a progressive system. Casinos would be able to conduct bonus periods on any combination of tables and games. For example, bonus periods could be conducted on one table, or on multiple tables, and either at the same time or at differing times. In addition, bonus periods could apply to blackjack alone or to blackjack and/or other card games. 
     As an example, the special casino chips  220  encrypted as shown in FIG. 3 could be utilized as a scheduled promotional event such as during the dinner hour when table games typically experience a decline in players. Casinos could handout such special chips  220  to players for use during these scheduled events. A computer system  250  would only recognize the use of the special chips  220  during the scheduled event. For example, in FIG. 4, the scheduled event  400  could occur between 7:00 p.m. and 9:00 p.m. The computer system  250  has a real time clock. Should a player upon receiving the special bonus chip  220  sit at table  10  and insert chip  220  in bet  200  at times outside of the scheduled event  400 , the computer  250  would ignore the special chip  220 . However, if the player P places bet  200  with the computer chip  220  in betting area  30  during the scheduled event time  400 , the computer system  250  would recognize the player P as participating in a progressive game or in a bonus, or other promotional pay out. 
     In FIG. 5, a number of game tables  10  are set forth interconnected to a controller  500  over a network  510 . The following represents an example and is not meant to limit the teachings of the present invention. Players P 1 , P 3 , P 5 , P 8 , and P 9  receive from the casino special chip  220  which is placed in a bet  200  along with the other chips  210 . In FIG. 5, these players have their special chip  220  indicated as a darkened circle. It is to be expressly understood that other chips  210  may be present and that players P 2 , P 4 , P 6 , and P 7 , in this example, do not have special chip  220 . The controller  500  having a real time clock only senses the presence of chips  220  during the time  400  of the scheduled event shown in FIG.  4 . This special chip  220  is sensed by each computer  250  and delivered to controller  500 . Controller  500  can incorporate a conventional MYSTERY JACKPOT™ such as that fully taught in U.S. Pat. No. 5,280,909 (Tracy). The presence of special chips  220  at player positions P 1 , P 3 , P 5 , P 8 , and P 9  qualifies those players to also receive a MYSTERY JACKPOT™. This adds excitement to the live card game, attracts players to the tables, and increases the casino&#39;s business. While the above example sets forth scheduling the award of a MYSTERY JACKPOT™ during a time scheduled event  400  time frame, the teachings of the present invention are not to be limited to a scheduled event  400 . 
     For example, in using the players P 1 , P 3 , P 5 , P 8 , and P 9  of the illustration in FIG. 5, such players could be awarded the special chip  220  based on their player performance such as monitored by a player tracker card which could be based upon length of time playing, amount of money won, amount of money played, or whatever suitable parameter the casino could use. The controller  500  would continuously run a separate bonus game such as MYSTERY JACKPOT™ in which event, the controller  500  would not be limited to a scheduled event time period  400  as shown in FIG. 4 but would continuously run the bonus period so that those players having the special chip  220  could always be included in a random jackpot bonus or other promotional period. The bonus pool can be funded independently by the casino, by a separate buy-in by the player, or by a percentage of the value of the chip  220 . 
     It is to be expressly understood that the chips  220  could be used in a number of different capacities. These capacities include, but are not limited to, the following: 
     1. Carry a denominational value and be used to participate in a bonus promotion or progressive game. 
     2. Not carry a denominational amount, but qualify the player to participate in a bonus game or promotion either during a predetermined scheduled event time frame  400  or at any time. 
     3. Used as a promotional incentive distributed via marketing to potential players to entice them to play a live card game. 
     4. The special chips  220  can be part of a series of special chips with each special chip for a different promotion, even constituting restricted chips for junket play (that is, for special, predefined groups, chips could be issued to members of those groups allowing, for example, play on certain games for certain amounts or certain promotions). 
     It is to be understood that in all the embodiments discussed above, the players P use the special chips  220  without affecting or slowing down their normal speed of play. The only exception to this process would be to either sell or dispense the special chips to the player or to pay a winner. 
     Furthermore, the special chips  220  could be utilized to create a distinguishable signal that could be used to increment a meter, fund a bonus pool, fund a promotion, or as a triggering device. 
     The above disclosure sets forth a number of embodiments of the present invention. Other arrangements or embodiments, not precisely set forth, could be practiced under the teachings of the present invention and as set forth in the following claims.
