Summary of the Invention

Problems to be Solved by the Invention

[0005] In conventional RFID-equipped substitute coins for gaming, after writing necessary information to a memory area where information can be written by a user, the memory area is locked to prevent unauthorized rewriting. In such substitute coins for gaming based on the prior art, it was possible to determine the authenticity of the substitute coin itself by grasping the information written in the memory area through RFID reading. However, RFID cannot store information obtained during use at a casino. Therefore, even if it is a genuine substitute coin for gaming, if it has an abnormal usage history in terms of usage status, such as not having been used for a long time or having been used or exchanged by an owner different from the original owner, its existence cannot be grasped by RFID reading, and it was impossible to prevent such substitute coins for gaming with an abnormal usage history from being used at a casino. There is an issue that there is a concern that substitute coins for gaming at a casino may be used for crimes such as money laundering by taking advantage of the fact that the history (history of location-related information) of the substitute coin for gaming is unknown, and a solution is sought.

[0006] Therefore, in the present invention, it is possible to write information to an RFID tag later, and the RFID tag of the substitute coin for gaming itself holds the usage history of the substitute coin for gaming, so that it is possible to discover an unauthorized substitute coin for gaming with an abnormal usage history based on the written usage history. An object of the present invention is to provide a substitute coin for gaming and a management system.

[0007] In order to solve the above-mentioned conventional problems, the management system for substitute coins for gaming of the present invention is provided with a single RFID tag having an area where data cannot be rewritten and an area where data can be rewritten on a substitute coin for gaming. The area where data of the RFID tag cannot be rewritten stores, as fixed information, at least one of production information, product information, casino information, amount information, and serial number of the substitute coin for gaming. The area where the data can be rewritten stores information regarding the location of the game substitute currency as variable information. It is configured such that the variable information stored in the area where the data can be rewritten can be extracted from the fixed information stored in the area where the data cannot be rewritten in the same RFID tag. The system further includes a writing device that adds information regarding the location of the game substitute currency to the area where the data can be rewritten, a reading device that collectively reads the fixed information stored in the areas where the data of a plurality of the game substitute currencies cannot be rewritten, and reads the information regarding the location stored in the area where the data can be rewritten corresponding to each piece of the read fixed information based on the read fixed information, and a management control device that examines the information regarding the location obtained from the reading device. The area where the data can be rewritten stores a plurality of pieces of information regarding locations, including at least the latest information regarding the location among all the information regarding locations written by the writing device.

Embodiments for Carrying Out the Invention

[0021] First, substitute gaming currency used in the management system of substitute gaming currency according to an embodiment of the present invention will be described. FIG. 1 shows substitute gaming currency 1 used in the system. In the figure, an RFID tag 2 capable of storing various information is embedded in the substitute gaming currency 1. The RFID tag 2 includes a region 21 where data cannot be rewritten and a region 22 where data can be rewritten.

[0022] In the region 21 where data cannot be rewritten, as fixed information 3, information that does not change, or information that has not changed, or information that must not be changed during the use of the substitute gaming currency 1 is stored. Specifically, as the fixed information 3, production information, product information, casino information, amount information, serial number, etc. of the substitute gaming currency 1 are stored. The production information includes the date and time when the substitute gaming currency was manufactured, the manufacturing machine, etc. The product information includes information indicating that it is a chip for the VIP area of a casino, information indicating the type of chip (e.g., information indicating that it is a rolling chip or a cash chip), etc.

[0023] The region 21 where data cannot be rewritten may be a region where writing is functionally impossible due to the specifications of the RFID tag, or a region where necessary information has been written in a writable region and then locked so that data cannot be written.

[0024] In the region 22 where data can be rewritten, as variation information 4, information that changes during the use of the substitute gaming currency 1 is stored. For example, as the variation information 4, as shown in FIG. 1, location-related information 220 including information 221 regarding date and time, information 222 regarding location and event, information 223 regarding the owner, etc. is stored.

[0025] The fixed information 3 and the variable information 4 may be encrypted to prevent unauthorized reading or writing of the information by others. Further, the fixed information 3 and the variable information 4 may be stored as metadata.

[0026] FIG. 2 shows an example of a method for recording data of the variable information 4 of the gaming substitute currency 1. As shown in FIG. 2, the information 220 regarding the location, which consists of the date and time, the time information 221, the location, the event information 222, and the owner information 223, is regarded as a single block, and the information of the blocks is connected in a chain so that the history of the information 220 regarding the location of the gaming substitute currency 1 can be grasped.

[0027] FIG. 2 shows an example of the variable information 4 stored in the gaming substitute currency 1, and the movement of the gaming substitute currency 1 as follows can be grasped. At 16:02 on January 28, 2019, Mr. A exchanges cash for the gaming substitute currency 1 at the cage 5. At 16:15 on the same day, Mr. A uses the gaming substitute currency 1 to place a bet at Table No. 325. At 16:43 on the same day, Mr. B receives the gaming substitute currency 1 as a repayment for winning the bet at Table No. 325. At 17:01 on the same day, Mr. B leaves the casino with the gaming substitute currency 1.

[0028] The variable information 4 may be configured to store only the latest information as shown in FIG. 2, or may store all the information regarding the written locations. Further, some of the information regarding a plurality of locations may be selectively stored. When selectively storing some, a plurality of information regarding locations including at least the latest information 220 regarding the location of all the information 220 regarding the location may be stored. With the above configuration, the history of the use or movement of a certain gaming substitute currency 1 can be understood from the variable information 4 of the gaming substitute currency 1. That is, the traceability information of the gaming substitute currency 1 is written in the gaming substitute currency 1 itself and is configured to be graspable.

[0029] Next, the management system of the gaming substitute currency 1 of the present embodiment will be described. FIG. 3 shows an overall overview of the system.

[0030] First, in the factory 6, for the gaming substitute currency 1, the variable information 4 including the information on the completion of manufacturing or factory shipment is written by the writing device 14 into the area 22 where the data of the RFID tag 2 can be rewritten as the location-related information 220.

[0031] The gaming substitute currency 1 shipped from the factory 6 undergoes acceptance processing in the casino's backyard 7. In the backyard 7, the reading device 13 reads the variable information 4 stored in the area 22 where the data of the gaming substitute currency 1 can be rewritten. Based on the reading result, the management control device 15 determines whether the location-related information 220 indicating that it has been written in the factory 6 is written as the latest variable information 4. If there is no writing record in the factory 6, an error signal is generated as a gaming substitute currency suspected of being illegal. As a result, it becomes possible to reject the acceptance of the gaming substitute currency on the casino side or request an investigation from the factory side. If there is no problem with the writing record, the writing device 14 writes the location-related information 220 indicating the backyard into the area 22 where the data of the RFID tag 2 can be rewritten. At the time of writing, the location information indicating the backyard may be described in addition to the location information indicating the factory, or the location information indicating the factory may be deleted and the location information indicating the backyard may be described. Also, the reading and writing of the gaming substitute currency in the above-mentioned backyard 7 can be performed in conjunction with the normal validation and activation operations of the gaming substitute currency.

[0032] The gaming substitute currency 1 that has completed the acceptance inspection in the backyard 7 is transported to the casino warehouse 8 or the cage 9. In the warehouse 8 or the cage 9, the reading device 13 reads the variation information 4 stored in the area 22 where the data of the gaming substitute currency 1 can be rewritten. Based on the reading result, the management control device 15 determines whether the information 220 regarding the location indicating that it was written in the backyard 7 is written as the information to be written as the latest variation information 4. Also, it may be possible to collectively inspect whether information indicating the factory 6 is written in the history of the variation information 4. The management control device 15, similar to the inspection in the aforementioned backyard 7, determines whether there are any abnormalities in the history of the location information. If there are no problems with the reading result, the writing device 14 writes the information 22 regarding the location indicating the warehouse 8 or the cage 9 in the area 22 where data can be rewritten.

[0033] The player purchases the gaming substitute currency 1 at the cage 9. When the player purchases the gaming substitute currency 1, the writing device 14 in the cage 9 writes the time when the gaming substitute currency was purchased and the information indicating that the owner of the gaming substitute currency has changed from a casino customer as the variation information 4. The player may be configured to be identified and recorded using face recognition technology, an ID card such as a casino membership card or a My Number card.

[0034] The player uses the exchanged gaming substitute currency 1 and places the gaming substitute currency 1 in the betting area 11 on the gaming table to place a bet. The reading device 13 reads the information 220 regarding the location, consisting of the date and time, time information 221, location, event information 222, and owner information 223, from the RFID tag 2 of the bet gaming substitute currency 1, and the management control device 15 determines whether there are any abnormalities. For example, if a certain period of time has passed since the date and time of the information on the use at the gaming table or the information on the exchange at the cage, which was last written, or if the owner information 223 stored in the gaming substitute currency 1 is different from the owner information 223 identified by face recognition or an ID card, it can be determined as an abnormality.

[0035] When there is no problem with the reading result, for the bet game substitute currency 1, the writing device 14 adds location-related information 220 to the rewritable data area 22. The location-related information 220 includes date and time, time information 221, location, event information 222, and owner information 223. In the table, for example, variable information 4 including the player position number where the game substitute currency 1 is placed and player information is written by the writing device 14. The player information may be identified by an ID card or face authentication. Usually, since multiple game substitute currencies 1 are stacked and placed in the bet area 11, writing is performed collectively in the stacked state.

[0036] When the player takes out the game substitute currency 1 from the casino floor, the player undergoes the exit process at the gate 10. At the time of exit, the location-related information 220 is read by the reading device 14, and the management control device 15 determines whether there is any abnormality in the variable information 4. Also at the gate 10, the writing device 14 writes variable information 4 including the location and event information 222 indicating exit and the owner information 223.

[0037] When the player brings in the game substitute currency 1 that was previously taken out when entering the casino floor, the reading device 13 reads the location-related information, and the management control device determines whether there is any abnormality in the variable information 4. For example, for the game substitute currency 1 that has once been taken out of the casino, if the owner at the time of exit from the casino is different from the owner at the time of entry, it can be grasped that there has been an act of transferring the game substitute currency outside the casino.

[0038] When the determination based on the reading result of the reading device 13 is abnormal, the management control device 15 described above may output an alarm to the cage 9 or the gate 10. When the owner of the gaming substitute currency 1 exchanges money at the cage 9 or exits from the gate 10, the money exchange can be rejected based on the alarm output by the management control device 15, or individual checks can be performed at the time of exit. Further, when the determination result is abnormal, the management control device 15 may issue a warning to interrupt the game to the dealer of each gaming table, issue a warning to the pit, and the pit manager may make a determination such as interrupting or continuing the game, or may make a determination on how to handle the exchange of the gaming substitute currency 1 or the like. Alternatively, the management control device 15 may be connected to the overall management control device 18 of the casino and may be configured to issue a warning to the overall management control device 18.

[0039] Similarly, when money is exchanged at the cage, the management control device 15 may read the change information 4 by the reading device 13 and determine if there is an abnormality. Specifically, an abnormality may be determined when a certain period of time has elapsed since the date and time of the information on use at the gaming table or the information on money exchange at the cage, which was last written, or when a person different from the owner information 223 stored in the gaming substitute currency 1 attempts to exchange money. When an abnormality is determined, the management control device 15 may output a warning and may reject the money exchange of the gaming substitute currency 1 for which an abnormality has been determined.

[0040] Also, in the above description, the form of reading by the reading device 13 and writing by the writing device 14 after determination by the management control device has been described, but a configuration in which reading and writing are performed simultaneously may also be used.

[0041] Hereinafter, details of an application example of the present invention will be shown.

[0042] At the factory 6, the RFID tag 2 is read and / or written at the time of production completion or at the time of shipment. Production information and product information are written as fixed information 3, locked so that they cannot be rewritten as necessary, and change information 4 is written.

[0043] In the backyard 6, when receiving the gaming tokens 1 shipped from the factory and activating them as usable gaming tokens 1, reading and / or writing of the RFID tag 2 is performed.

[0044] In the warehouse 8, when moving the gaming tokens 1 from the warehouse 8 to the cage 9 or moving the gaming tokens 1 from the cage 9 to the warehouse 8, reading and / or writing of the RFID tag 2 is performed. Alternatively, for the gaming tokens 1 stored in the warehouse 8, reading and / or writing of the RFID tag 2 may be performed at regular intervals or at a predetermined timing.

[0045] In the cage 9, when moving from or to the warehouse 8 and when exchanging the customer's cash for the gaming tokens 1, reading and / or writing of the RFID tag 2 is performed. When the exchange is made in the cage 9, the location indicating the exchange, the event information 222, and the player information indicating the player who made the exchange are written as the owner information 223 into the variable information 4. The owner information 223 can be obtained from the player's casino ID card, face recognition system, credit card, etc.

[0046] At the gate 10, when the player enters or exits, reading and / or writing of the RFID tag 2 is performed. For all the gaming tokens 1 taken out of the casino when the player exits, the location indicating the taking out, the event information 222, and the owner information 223 indicating the player who takes out are written as the variable information 4 for registration. Similarly, when entering, the location indicating the bringing in, the event information 222, and the owner information 223 indicating the player who brings in are written as the variable information 4 for registration of the gaming tokens 1 brought into the casino.

[0047] In the bet area 11, reading and / or writing of the RFID tag 2 is performed on the gaming tokens 1 placed in the bet area 11 for the player to participate in the bet. Also, reading and / or writing of the RFID tag 2 is performed on the gaming tokens 1 placed in the bet area 11 by the dealer as the repayment to the player.

[0048] In the chip tray 12, reading and / or writing of the RFID tag 2 is performed on the gaming tokens 1 collected in the chip tray and the stored gaming tokens 1.

[0049] The gaming table further includes a payment area, and the dealer may perform reading and / or writing of the RFID tag 2 on the gaming tokens 1 placed in the bet area 11 as repayment money to the player.

[0050] In this way, on the gaming table, the variable information 4 (that is, the location-related information 220) can be updated at the timing when the gaming tokens 1 are bet (betting timing), the timing when they are collected by the dealer (collection timing), and the timing of payment from the dealer to the player (payment timing). The variable information 4 may be updated at all of these betting timing, collection timing, and payment timing, or the variable information 4 may be updated at some of these timings.

[0051] FIG. 7A shows an example of updating the variable information 4 at all of the betting timing, collection timing, and payment timing. By updating the variable information 4 at these timings, the movement of the gaming tokens 1 as follows can be grasped. At 16:27 on January 28, 2019, Player C exchanges cash and gaming tokens 1 at the cage 5 (update U701). At 16:35 on the same day, Player C bets the gaming tokens 1 at the seat of Player Position No. 1 on Table No. 321 (update U702). Player C loses the game, and at 16:38 on the same day, the gaming tokens 1 are collected in the chip tray 12 (update U703). Thereafter, Player D wins the game at Player Position No. 3 on the same table, and at 16:52 on the same day, the dealer pays the gaming tokens 1 to Player D (update U704).

[0052] According to this example, first, as the owner information 223 among the variable information 4, dealer or information of any player can be written, so the history of the owner can be accurately grasped. In particular, according to this example, a state where the actual owner always matches the owner information can always be realized. Note that in the bet state, the owner information 223 may remain as the betting player, or may be information indicating that it is neither a player nor a dealer but is being bet.

[0053] Figure 7B shows an example of updating the variable information 4 at the bet timing and the recovery timing. By updating the variable information 4 at these timings, the movement of the substitute gaming currency 1 can be grasped as follows. At 16:28 on January 28, 2019, Mr. E exchanges cash and the substitute gaming currency 1 at the cage 5 (update U705). At 16:36 on the same day, Mr. E bets the substitute gaming currency 1 at the seat of player position No. 2 on table No. 322 (update U706). Mr. E loses the game, and at 16:39 on the same day, the substitute gaming currency 1 is recovered into the chip tray 12 (update U707). The substitute gaming currency 1 is paid from the chip tray 12 to Mr. F who won the game, and Mr. F bets the substitute gaming currency 1 at the seat of player position No. 4 on table No. 322 at 16:53 on the same day (update U708).

[0054] According to this example, for the substitute gaming currency 1 in the chip tray 12 (that is, owned by the casino), it is known from which player it was recovered. Also, for the substitute gaming currency 1, it is known that the casino has indeed recovered it from the player.

[0055] FIG. 7C shows an example of updating the variable information 4 at the bet timing and the payment timing. By updating the variable information 4 at these timings, the movement of the game substitute currency 1 can be grasped as follows. At 16:29 on January 28, 2019, Mr. G exchanges cash and the game substitute currency 1 at the cage 5 (update U709). At 16:37 on the same day, G bets the game substitute currency 1 at the seat of player position No. 3 at table No. 323 (update U710). After Mr. G loses the game and the game substitute currency 1 is collected in the chip tray 12, at 16:53 on the same day, the dealer pays the game substitute currency 1 to Mr. H who won the game at the seat of player position No. 5 at the same table (update U711).

[0056] According to this example, the betting of each player and the payment (repayment) to each player can be grasped. Also, for example, if after Mr. G's bet, Mr. H bets without going through the payment to Mr. H, it can be grasped that the game substitute currency was directly transferred from Mr. G to Mr. H.

[0057] FIG. 7D shows an example of updating the variable information 4 at the collection timing and the payment timing. By updating the variable information 4 at these timings, the movement of the game substitute currency 1 can be grasped as follows. At 16:29 on January 28, 2019, Mr. I exchanges cash and the game substitute currency 1 at the cage 5 (update U712). As a result of Mr. I betting the game substitute currency 1 at the seat of player position No. 4 at table No. 324, Mr. I loses the game, and at 16:40 on the same day, the game substitute currency 1 is collected in the chip tray 12 (update U713). At 16:54 on the same day, the dealer pays the game substitute currency 1 to Mr. J who won the game at the seat of player position No. 6 at the same table (update U714).

[0058] Also according to this example, as the owner information 223 in the variable information 4, the information of the dealer or any player can be written, so the history of the owner can be accurately grasped. In particular, according to this example, a state where the actual owner and the owner information always match can be realized.

[0059] FIG. 7E shows an example of updating the variation information 4 at the bet timing. By updating the variation information 4 at the bet timing, the movement of the game substitute currency 1 can be grasped as follows. At 16:30 on January 28, 2019, Mr. K exchanges cash and the game substitute currency 1 at the cage 5 (update U715). At 16:38 on the same day, Mr. K bets the game substitute currency 1 at the seat of player position No. 5 on table No. 325 (update U716). After Mr. K loses the game and the game substitute currency 1 is collected in the chip tray 12, Mr. L at player position No. 1 on the same table wins the game and receives the payment of the game substitute currency 1. Then, at 16:50 on the same day, Mr. L bets the game substitute currency 1 at the same player position on the same table (update U717). Since Mr. L won that game, after putting the game substitute currency 1 away, at 16:59 on the same day, Mr. L bets the game substitute currency 1 at the same player position on the same table (update U718).

[0060] According to this example, it is possible to grasp how the player who owns the game substitute currency 1 has changed via the chip tray 12. Also, it can be grasped that the game substitute currency 1 has indeed been bet. Thereby, it can be confirmed that it is not being used for money laundering.

[0061] Figure 7F shows an example of updating the variable information 4 at the collection timing. By updating the variable information 4 at the collection timing, the movement of the gaming substitute currency 1 can be grasped as follows. At 16:28 on January 28, 2019, Mr. M exchanges cash and the gaming substitute currency 1 at the cage 5 (update U719). When Mr. M bets the gaming substitute currency 1 at the seat of player position No. 6 on table No. 326 and loses the game, the gaming substitute currency 1 is collected into the chip tray 12 at 16:39 on the same day (update U720). After that, Mr. N wins the game at the seat of player position No. 2 on the same table and receives the payment of the gaming substitute currency 1. Then, Mr. N bets the gaming substitute currency 1 at the same player position on the same table in the subsequent game, loses the game, and the gaming substitute currency 1 is collected into the chip tray 12 at 16:59 on the same day (update U721).

[0062] According to this example, it is possible to know where and when the gaming substitute currency 1 was used on which gaming table. When fraud is suspected, the video of the corresponding gaming table during the corresponding time period can be verified, and it can be confirmed that it was not used for money laundering.

[0063] Figure 7G shows an example of updating the variable information 4 at the payment timing. By updating the variable information 4 at the payment timing, the movement of the gaming substitute currency 1 can be grasped as follows. At 16:29 on January 28, 2019, Mr. O receives the payment of the gaming substitute currency 1 at the seat of player position No. 7 on table No. 327 (update U722). After that, since Mr. O bets the gaming substitute currency 1 on the same table and loses the game, the gaming substitute currency 1 is collected into the chip tray 12. Then, Mr. P wins the game at player position No. 3 on the same table, and the dealer pays Mr. P the gaming substitute currency 1 at 16:43 on the same day (update U723).

[0064] According to this example, for the gaming substitute currency 1 owned by the player, it is possible to grasp at which gaming table the payment was received. As a result, it can be determined that it was not stolen from the chip tray, and it can be confirmed that it was not used for money laundering.

[0065] As described above, in the management system of this embodiment, at the gaming table, the variable information 4 (that is, the location-related information 220) is updated at at least one of the bet timing, the collection timing, and the payment timing.

[0066] Note that, in the above example, the update of the variable information 4 at the collection timing may be performed in the bet area or in the chip tray. In the operation of the baccarat game, after collecting the bet chips of the losing player first, the payment to the winning player is made. Therefore, for the gaming substitute currency 1 of the winning player, a relatively long time can be ensured for updating the variable information 4 in the bet area, and the variable information 4 can be updated relatively reliably also in the bet area.

[0067] On the other hand, for the gaming substitute currency 1 to be collected, since the time it exists in the bet area from when it is determined to be collected (after the game result is determined) until it is collected is relatively short, if an attempt is made to update the variable information 4 in the bet area, it is conceivable that the update will not be in time. Therefore, for the gaming substitute currency 1 to be collected, it is advantageous to rewrite the variable information 4 in the chip tray which is the collection destination.

[0068] The management control device 15 has a function of determining whether there is an abnormality in the location-related information 220 obtained from the reading results of the reading devices 13 at each location. As the determination of whether there is an abnormality, it is possible to determine whether there is any event that it has not been used for a predetermined period or more since the previous writing, or the location-related information that should have been written has not been written.

[0069] The event that it has not been used for a predetermined period or more since the previous writing is 1) The information indicating the latest location is the information indicating the cage 9, and the writing of the following information has been elapsed for a predetermined time or more. 2) The information indicating the latest location is the information indicating the entry at the gate 10, and the writing of the following information has been elapsed for a predetermined time or more. 3) The information indicating the latest location is the information indicating the exit at the gate 10, and the writing of the following information has been elapsed for a predetermined time or more. It is any of the above situations.

[0070] The event that the information regarding the location to be written is not written is 4) When entering the game arcade, as the information regarding the latest location of the area 22 where the data of the game substitute currency 1 can be rewritten, the information indicating the exit at the gate 10 is not written. 5) When using the cage 9, the information indicating the backyard 7 is not written. 6) When exiting the game arcade, the information indicating the cage 9 or the backyard 7 is not written. It is any of the above situations.

[0071] Based on the information 223 regarding the owner obtained from the reading device 13, the management control device 15 determines whether it is abnormal as an event 1) A person different from the final owner stored in the area 22 where data can be rewritten exchanges, exchanges, or exits the game arcade with the game substitute currency 1. 2) A person different from the owner at the time of exit stored in the area 22 where data can be rewritten brings the game substitute currency into the game arcade. It is possible to determine any of the above situations.

[0072] Based on the information indicating the location of the bet area 11, the location of the chip tray 12, or the information indicating the payment area obtained from the reading device 13, the management control device 15 determines whether it is abnormal as an event 1) A person different from the final owner storing in the rewritable area 22 of the data uses the gaming substitute currency 1 on the gaming table. 2) A person different from the person at the time of purchase of the gaming substitute currency 1 in the cage 9 of the gaming substitute currency 1, which has no usage record on the gaming table, exchanges it for money in the cage 9. 3) The gaming substitute currency 1 without information indicating the cage 9 or the backyard 7 is used inside the casino. 4) The information regarding the latest location is information indicating the bet area 11 or the payment area, and after a lapse of a predetermined period or more, it is exchanged for money in the cage 9 or used on the gaming table. Determine any one of the situations from 1) to 4) above.

[0073] FIG. 6 shows a database according to another embodiment of the present invention. The management system further includes a database 17 that records similar fixed information 3 and variable information 4 in addition to the gaming substitute currency 1. Based on the reading result of the reading device 13, the management control device 15 records information in the database 17 and collates the fixed information 3 and variable information 4 stored in the gaming substitute currency 1 with the information in the database to determine an abnormality.

[0074] In the RFID tag 2 in the embodiment of the present invention, the functionally non-writable area of the area 21 where data cannot be rewritten may be the TID. After writing the necessary information in the area 21 where data cannot be rewritten, the locked area where data cannot be written may be the EPC or the user area. The rewritable area 22 may be the EPC or the user area.

[0075] The reading device 13 and the writing device 14 may vary in form depending on the location. For example, in the factory 6, it is on a table as shown in FIG. 4, in the gate 10, it is box-shaped, and in the bed area 11 and the chip tray 12, the bed area 11 and the chip tray 12 themselves may have the functions of the reading device 13 and the writing device 14. Also, the gaming substitute coins 1 may be stacked as they are, or reading and writing may be performed while they are stored in a chip case or the like. Further, the reading device 13 and the writing device 14 may be integrated.

[0076] In the above embodiment, the case where there is one RFID tag on the gaming substitute coin and the single RFID tag has an area where data cannot be written and an area where data can be rewritten has been described. On the other hand, a form in which two RFID tags are inserted into the gaming substitute coin, one RFID tag stores fixed information and is locked so that data cannot be written, and the other RFID tag is made capable of rewriting data in order to record variable information, is also conceivable.

[0077] However, in this case, when a plurality of gaming substitute coins are read collectively, as shown in FIG. 5A, since the information group of the fixed information 3 and the information group of the variable information 4 are read separately, the combination of the fixed information and the variable information of a specific gaming substitute coin cannot be determined, and there is a problem that a gaming substitute coin with an abnormality in the variable information cannot be identified.

[0078] On the other hand, when there is one RFID tag, as shown in FIG. 5B, since the mutual correspondence relationship between the fixed information and the variable information read by the reading device can be grasped even when a plurality of gaming substitute coins are read collectively, it is considered better to implement it with a single RFID tag.

[0079] In general, the larger the diameter of an RFID tag, the higher the reading accuracy. Therefore, when an RFID tag is inserted into a gaming token, it is desirable for the RFID tag to have a diameter of at least the radius of the gaming token. However, inserting two RFID tags into a gaming token is not preferable as it would reduce the diameter of each individual RFID tag. Also, inserting two RFID tags would increase the number of RFID tags to be read, leading to a decrease in the reading speed when reading multiple gaming tokens.

[0080] In view of the above, it is considered more effective to implement with a single RFID tag.
