Description

[Technical Field]

[0001] The present invention relates to a gaming token management system that prevents fraudulent gaming tokens from being used in casinos and other gaming facilities that use gaming tokens. [Background technology]

[0002] Baccarat and blackjack are among the many table games played in casinos and other gaming establishments. Casinos use gaming tokens to play these games.

[0003] The use of fraudulent gaming tokens must not occur in casinos. To prevent the use of counterfeit gaming tokens in casinos, casinos have technology in place to attach RFID tags to gaming tokens to determine their authenticity and prevent the use of counterfeits. RFID-equipped gaming tokens are publicly known and are disclosed in Patent Document 1 (International Application Publication No. WO2008 / 120749). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Application Publication No. WO2008 / 120749 Summary of the Invention [Problem to be solved by the invention]

[0005] With gaming tokens based on conventional technology, it was possible to determine the authenticity of the gaming token itself by reading the RFID and understanding the information written in the memory area. However, it was not possible to record or determine information obtained during use at a casino, particularly information about the owner of the gaming token. Therefore, if a gaming token is genuine but has an abnormal usage history, such as being used or exchanged by a different owner than the original owner, its existence cannot be detected by reading the RFID, and it was not possible to prevent such gaming tokens with abnormal usage history from being used in casinos.

[0006] Therefore, the present invention aims to provide a system that constantly grasps and manages the owner information of each gaming token, thereby increasing security, and that when a dealer pays gaming tokens to a player and the ownership of the gaming tokens is transferred from the casino to a player, makes it possible to grasp and record to which player the ownership of the gaming tokens has been transferred.

[0007] In order to solve the above-mentioned conventional problems, the gaming currency management system of the present invention provides: gaming currency with an individually identifiable RFID tag attached; a gaming table for playing games using the gaming currency; a chip placement area in the gaming table where betting chips placed by players participating in a game and payment chips paid out by a dealer to a winning player from a chip tray of the gaming table are placed; A chip reader that reads the RFID of the gaming currency placed in the chip placement area; A control device that grasps the reading result of the chip reading device, The control device is capable of acquiring information about the owner of the gaming currency based on the RFID ID information of the gaming currency, Furthermore, the control device is configured to recognize that the winning player's betting chips and the payment chips paid out to the winning player are moved out of the chip placement area, and to associate, in a database, ID information of the payment chips with ID information of the betting chips that moved out of the chip placement area at the same time as the payment chips, The system has a function of associating, in a database, the ID information carried by the RFID tag of the payment chip with information about the owner of the betting chip indicated by the RFID tag of the betting chip.

[0008] Furthermore, the chip placement area is configured to be partitioned for each player position, and each player position is provided with a pay area for placing the payment chips, The chip reader may be configured to be able to read the pay area separately for each player position.

[0010] (First embodiment) An overview of the entire table game management system according to the first embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a diagram showing an overview of the entire system. A gaming table 1004 for a baccarat game has betting areas for player 1441, banker 1442, tie 1443, player pair 1444, and banker pair 1445, for each of player positions 1131 to 1135. A chip placement area 1025 is also provided for each player position, and a chip reader 1002 is provided for reading the RFID of gaming currency 1001 placed within the chip placement area.

[0011] Furthermore, each chip placement area 1025 is provided with a pay area 1026 for placing gaming currency 1001 taken out from the chip tray 1009 of the gaming table 1004 when the dealer pays out gaming currency 1001 to a winning player from the chip tray 1009.

[0012] Furthermore, the device further includes a control device 1003 that grasps the results of reading the RFID of the gaming currency 1001 read by the chip reader 1002.

[0013] First, a player participating in a game bets gaming currency 1001 in a betting area within the chip placement area. The chip reader 1002 reads the RFID of the bet gaming currency 1001, and the control device 1003 obtains information about the owner of the gaming currency 1001 that is associated in the database with the ID information of the RFID.

[0014] If the casino wins based on the result of the game, the dealer collects the gaming currency 1001 bet by the losing player and places it in the chip tray 1009. The RFID of the gaming currency 1001 in the chip tray 1009 is detected by the chip reader 1002, and the control device 1003 records in the database that the owner of the gaming currency 1001 collected by the casino is the casino.

[0015] Based on the result of the game, the dealer pays out to the winning player gaming currency 1001 from the chip tray in an amount corresponding to the amount of the bet chips, in accordance with the rules of the game.

[0016] When making a payout, the pay chips may be placed in the pay area 1026 described above, or in a chip placement area other than the pay area.

[0017] Here, a method for recording information about the owner of a payment chip will be described with reference to Fig. 2. Fig. 2 shows a method for recording information about the owner of gaming currency 1001 when paying a chip to a winning player.

[0018] When multiple players place betting chips at the same player position, resulting in two or more stacks, the chip reader 1002 reads all of the gaming currency 1001 placed in the chip placement area 1025 at once, and therefore, during the game, acquires the ID 1010 of the bet gaming currency without knowing which gaming currency 1001 belongs to which player. After the outcome of the game is determined, when making payments to the winning players, the dealer pays out the gaming currency 1001 from the chip tray 1009 for each player (each stack). The gaming currency 1001 removed from the chip tray 1009 is placed in the chip placement area 1025. The chip reader 1002 reads the ID 1011 of the payment chip placed in the chip placement area 1025.

[0019] The paid-out gaming currency 1001 is received by the winning player together with the gaming currency 1001 that was initially bet. At this time, the betting chip and payment chip are moved outside the chip placement area 1025, so the IDs of the betting chip and payment chip disappear from the reading results by the chip reader 1002. As a result, the control device 1003 knows to which player the paid-out payment chip has been paid out by associating it with information about the owner of the betting chip.

[0020] The control device 1003 stores information about the owner of the payment chip in association with the ID of the gaming currency in a database.

[0021] As a result of the above, it becomes possible to trace the owner of the gaming currency 1001, and if there is any fraudulent transfer of the gaming currency 1001, it becomes possible to discover that the owner information stored in the database differs from the actual owner.

[0022] The actual owner can be identified by using facial recognition technology or ID such as a membership card.

[0023] In the above explanation, the ID of each gaming currency is managed on a database, but the gaming currency 1001 itself may store owner information.

[0024] In addition, the above-mentioned pay area 1026 may be provided for each player position, or may be configured as an area independent of each player position, and reading by the chip reader 1002 may be performed independently.

[0025] Furthermore, the configuration may be such that it is possible to select whether or not to use the pay area 1026 depending on the reading performance of the chip reader 1002.

[0026] Furthermore, this table game management system may be linked to an RFID reader that reads the chips in the chip tray 1009 using RFID, a camera that reads the bet chips, a shoe that determines the outcome of the game, and other outcome determination devices, and may be configured to allow information to be used mutually.

[0027] (Second embodiment) First, a gaming token used in a gaming token management system according to an embodiment of the present invention will be described. Fig. 3 shows a gaming token 1 used in the system. In the figure, an RFID tag 2 capable of storing various information is embedded in the gaming token 1. The RFID tag 2 has an area 21 where data cannot be rewritten and an area 22 where data can be rewritten.

[0028] The area 21 where data cannot be rewritten stores fixed information 3, which is information that does not change while the gaming token 1 is being used, information that does not change, or information that must not be changed. Specifically, the fixed information 3 stores production information, product information, casino information, amount information, serial number, etc. of the gaming token 1. The production information includes the date and time the gaming token was manufactured, the manufacturing machine, etc., and the product information includes, for example, information indicating that the gaming token is a chip for the VIP area of ​​a casino and information indicating the type of chip (for example, information indicating that it is a rolling chip or a cash chip), etc.

[0029] The area 21 where data cannot be rewritten may be an area where writing is functionally impossible due to the specifications of the RFID tag, or may be an area that is locked so that data cannot be written after the necessary information has been written in an area where data can be written.

[0030] The rewritable data area 22 stores variable information 4, which changes while the gaming token 1 is being used. For example, as shown in Fig. 3, the variable information 4 stores location-related information 220, which includes information 221 about the date and time, information 222 about the location and event, and information 223 about the owner.

[0031] The fixed information 3 and variable information 4 may be encrypted to prevent unauthorized reading or writing of the information by others, and may also be stored as metadata.

[0032] Fig. 4 shows an example of a method for recording data of the variable information 4 of the gaming token 1. As shown in Fig. 4, location-related information 220, which is made up of date and time information 221, location and event information 222, and owner information 223, is treated as a single block, and the information of the block is linked in a chain so that the history of the information 220 about the location of the gaming token 1 can be grasped.

[0033] Figure 4 shows an example of variable information 4 stored in gaming token 1, and the following movement of gaming token 1 can be understood. At 16:02 on January 28, 2019, Mr. A exchanges cash for gaming token 1 in cage 5. At 16:15 on the same day, Mr. A places a bet using gaming token 1 at table No. 325. At 16:43 on the same day, Mr. B receives gaming token 1 as redemption money for a winning bet at table No. 325. At 17:01 on the same day, Mr. B leaves the casino with gaming token 1.

[0034] The variable information 4 may be configured to store only the latest information as shown in FIG. 4, or may store all written information about locations. Also, some of the information about multiple locations may be selected and stored. When some information about multiple locations is selected and stored, information about multiple locations may be stored, including at least the information 220 about the latest location of all the information 220 about locations. With the above configuration, the variable information 4 of a certain gaming token 1 can reveal the history of use or movement of the gaming token 1. In other words, the traceability information of the gaming token 1 is written in the gaming token 1 itself, making it possible to understand it.

[0035] Next, a description will be given of the management system for the gaming token 1 of this embodiment. Figure 5 shows an overview of the entire system.

[0036] First, at the factory 6, the writing device 14 writes variable information 4 including information on completion of production or shipment from the factory as location information 220 into the data rewritable area 22 of the RFID tag 2.

[0037] The gaming token 1 shipped from the factory 6 undergoes an acceptance process in the casino's backyard 7. In the backyard 7, the reading device 13 reads the variable information 4 stored in the rewritable data area 22 of the gaming token 1. Based on the reading result, the management control device 15 determines whether location information 220 indicating that the information was written at the factory 6, which should have been written, has been written as the latest variable information 4. If there is no record of the information written at the factory 6, an error signal is generated indicating that the gaming token is suspected of being fraudulent. This allows the casino to refuse to accept the gaming token or to request an investigation from the factory. If there is no problem with the writing record, the writing device 14 writes the location information 220 indicating the backyard into the rewritable data area 22 of the RFID tag 2. When writing, location information indicating the backyard may be added 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 written instead. Furthermore, the reading and writing of gaming tokens in the backyard 7 can be carried out in conjunction with the normal validation and activation procedures for gaming tokens.

[0038] After the acceptance inspection in the back yard 7 is completed, the gaming token 1 is transported to the casino's warehouse 8 or cage 9. In the warehouse 8 or cage 9, the reading device 13 reads the variable information 4 stored in the rewritable data area 22 of the gaming token 1, and based on the reading result, the management control device 15 determines whether location information 220 indicating that the information was written in the back yard 7 has been written as the latest variable information 4, as information that should have been written. It may also be possible to check whether information indicating the factory 6 has been written in the history of the variable information 4. As with the inspection in the back yard 7 described above, the management control device 15 determines whether there are any abnormalities in the location information history. If there are no problems with the reading result, the writing device 14 writes location information 22 indicating the warehouse 8 or cage 9 into the rewritable data area 22.

[0039] A player purchases gaming tokens 1 in a cage 9. When a player purchases gaming tokens 1, a writing device 14 in the cage 9 writes the time the gaming token was purchased and information indicating that the ownership of the gaming token has changed from the casino to a customer as variable information 4. Players may be identified and recorded using facial recognition technology or an ID card such as a casino membership card or My Number card.

[0040] A player uses the gaming token 1 that has been exchanged for cash to place a bet in a betting area 11 at a gaming table. A reading device 13 reads location-related information 220, consisting of date and time information 221, location and event information 222, and owner information 223, from the RFID tag 2 of the gaming token 1 that has been bet, and a management control device 15 determines whether there is an abnormality. For example, if a certain period of time has passed since the last written date and time of use information at a gaming table or exchange information for cash at a cage, or if the owner information 223 stored in the gaming token 1 differs from the owner information 223 identified by face authentication or an ID card, an abnormality can be determined.

[0041] If there is no problem with the reading result, the writing device 14 writes location-related information 220 to the data-rewritable area 22 of the betted gaming token 1. The location-related information 220 includes date and time information 221, location and event information 222, and owner information 223. At the table, the writing device 14 writes variable information 4 including, for example, the player position number where the gaming token 1 is placed and player information. Player information may be identified by an ID card or facial recognition. Typically, multiple gaming tokens 1 are placed in a stack in the betting area 11, so writing is performed all at once while they are stacked.

[0042] When a player takes gaming token 1 off the casino floor, the player performs an exit process at gate 10. At the time of exit, location information 220 is read by reader 14, and management control device 15 determines whether there are any abnormalities in variable information 4. Also at gate 10, writing device 14 writes variable information 4 including location and event information 222 and owner information 223 indicating the exit.

[0043] When a player brings in gaming token 1 that he or she has previously taken out when entering the casino floor, information regarding its location is read by the reader 13, and the management control device determines whether there are any abnormalities in the variable information 4. For example, if the owner of gaming token 1 that was once taken out of the casino is different when the player leaves the casino from the owner when the player enters, it can be determined that the gaming token has been handed over outside the casino.

[0044] The above-mentioned management control device 15 may output an alarm to the cage 9 or gate 10 if the determination based on the reading result of the reader 13 is abnormal. When the owner of the gaming token 1 exchanges it for cash in the cage 9 or when exiting through the gate 10, the management control device 15 may refuse to exchange it for cash based on the alarm outputted by the management control device 15, or may perform an individual check at the time of exit. Furthermore, if the determination result is abnormal, the management control device 15 may issue a warning to the dealer at each gaming table to suspend the game, or may issue a warning to the pit, so that the pit manager can decide whether to suspend or continue the game, or decide how to deal with the situation, such as exchanging the gaming token 1. Alternatively, the management control device 15 may be connected to the casino's overall management control device 18 and issue a warning to the overall management control device 18.

[0045] Similarly, the management control device 15 may read the variable information 4 using the reader 13 when the token is exchanged for cash at the cage, and determine whether there is an abnormality. Specifically, an abnormality may be determined when a certain period of time has passed since the date and time of the last written information on use at the game table or exchange for cash at the cage, or when a person other than the owner information 223 stored in the gaming token 1 is attempting to exchange the token for cash. If an abnormality is determined, the management control device 15 may output a warning and refuse to exchange the gaming token 1 for cash for which an abnormality has been determined.

[0046] In the above description, the reading device 13 reads data, the management control device makes a decision, and then the writing device 14 writes data. However, the reading and writing may be performed simultaneously.

[0047] In the following, details of an embodiment of the application of the present invention are given.

[0048] At the factory 6, when production is completed or when products are shipped, the RFID tag 2 is read and / or written. Production information and product information are written as fixed information 3, and if necessary, this information is locked so that it cannot be rewritten, and variable information 4 is also written.

[0049] In the backyard 6, when the gaming token 1 shipped from the factory is received and activated as a usable gaming token 1, the RFID tag 2 is read and / or written.

[0050] In the warehouse 8, the RFID tag 2 is read and / or written when the gaming token 1 is moved from the warehouse 8 to the cage 9 or when the gaming token 1 is moved from the cage 9 to the warehouse 8. Alternatively, the RFID tag 2 may be read and / or written for the gaming token 1 stored in the warehouse 8 at regular intervals or at a predetermined timing.

[0051] The cage 9 reads and / or writes the RFID tag 2 when the tokens are moved to or from the warehouse 8, and when the gaming tokens 1 are exchanged for customer cash. When the exchange is performed in the cage 9, the variable information 4 is written as owner information 223, including the location indicating the exchange, event information 222, and information about the player who performed the exchange. The owner information 223 can be obtained from the player's casino ID card, a face authentication system, a credit card, etc.

[0052] At gate 10, when a player enters or leaves, the RFID tag 2 is read and / or written. When a player leaves, the location and event information 222 indicating the removal, and owner information 223 indicating the player removing the token are written as variable information 4 for all gaming tokens 1 that the player takes out, and registration is performed, and similarly when a player enters, the location and event information 222 indicating the bring-in, and owner information 223 indicating the player bringing the token are written as variable information 4 for registration of the gaming tokens 1 that the player brings into the casino.

[0053] In the betting area 11, the RFID tags 2 of the gaming tokens 1 placed in the betting area 11 by the players to place bets are read and / or written. Also, the RFID tags 2 of the gaming tokens 1 placed in the betting area 11 by the dealer as redemption money for the players are read and / or written.

[0054] In the chip tray 12, the RFID tags 2 are read and / or written to the gaming tokens 1 collected in the chip tray and the gaming tokens 1 stored therein.

[0055] The gaming table further includes a payment area including area 2007 and pay area 1026, which may read and / or write RFID tags 2 on gaming tokens 1 placed in the betting area 11 by the dealer as redemptions to the player.

[0056] The management control device 15 has a function to determine whether there is an abnormality in the location information 220 obtained from the reading results of the reading device 13 at each location. To determine whether there is an abnormality, it can determine whether there is either an event that the information has not been used for a predetermined period of time since the last time it was written, or the information about the location that should have been written has not been written.

[0057] Events that have not been used for a specified period of time since the last write are 1) The latest location information is information indicating the cage 9, and the next information has been written for more than a predetermined time. 2) The latest location information indicates entry at Gate 10, and the next information has been written for more than a specified time. 3) The latest location information indicates exit at Gate 10, and the next information has been written more than the specified time ago. This is one of the following situations.

[0058] The event where the information about the location that should have been written is not written is as follows: 4) When entering the gaming facility, information indicating exit at the gate 10 is not written as information regarding the latest location of the gaming token 1 in the data rewritable area 22. 5) When used in the cage 9, information indicating the backyard 7 is not written. 6) When leaving the amusement facility, there is no information written indicating the cage 9 or the backyard 7. This is one of the following situations.

[0059] The management control device 15 determines whether an abnormality exists based on the information 223 about the owner obtained from the reading device 13, as follows: 1) A person other than the final owner of the gaming token 1 stored in the data rewritable area 22 exchanges the gaming token 1 for cash or money within the gaming facility, or leaves the gaming facility. 2) A person other than the owner of the token at the time of exit, whose data is stored in the rewritable data area 22, brings the token into the gaming facility. It is possible to determine either of the following situations.

[0060] The management control device 15 determines whether an abnormality exists based on the information indicating the location of the betting area 11, the location of the chip tray 12, or the information indicating the payment area obtained from the reading device 13, as follows: 1) A person other than the final owner of the gaming token 1 stored in the data rewritable area 22 uses the gaming token 1 at a gaming table. 2) A person other than the person who purchased the gaming token 1 at the cage 9 exchanges the gaming token 1, which has no record of use at the gaming table, for cash at the cage 9. 3) A gaming token 1 without information indicating a cage 9 or a backyard 7 is used in the gaming facility. 4) The latest location information is information indicating the betting area 11 or the payment area, and after a predetermined period of time, the information is exchanged for cash in the cage 9 or used at the gaming table. Determine whether the situation is one of 1) to 4) above.

[0061] 8 shows a database according to another embodiment of the present invention. The management system further includes a database 17 that records the gaming token 1 as well as the fixed information 3 and variable information 4. The management control device 15 records information in the database 17 based on the results of reading by the reading device 13, and can also compare the fixed information 3 and variable information 4 stored in the gaming token 1 with the information in the database to determine whether there is an abnormality.

[0062] In the RFID tag 2 according to the embodiment of the present invention, the functionally unwritable area of ​​the unrewritable area 21 may be a TID. After necessary information is written in the unrewritable area 21, the area that is locked to prevent data from being written thereto may be an EPC or user area. The rewritable area 22 may be an EPC or user area.

[0063] The reader 13 and the writer 14 may take different forms depending on the location. For example, in the factory 6 they are on a table as shown in FIG. 6, while at the gate 10 they are box-shaped, and in the betting area 11 and the chip tray 12, the betting area 11 and the chip tray 12 themselves may have the functions of the reader 13 and the writer 14. Furthermore, the gaming tokens 1 may be stacked as they are, or may be read and written while housed in a chip case or the like. Furthermore, the reader 13 and the writer 14 may be integrated.

[0064] In the above embodiment, the gaming token has one RFID tag, and the single RFID tag has an area where data cannot be written and an area where data can be rewritten. Alternatively, a gaming token may have two RFID tags, one of which stores fixed information and is locked to prevent data from being written, and the other RFID tag stores variable information and is rewritable.

[0065] However, in this case, when multiple gaming tokens are read at once, the information group of fixed information 3 and the information group of variable information 4 are read separately, as shown in Figure 7A, so the combination of fixed information and variable information for a specific gaming token cannot be determined, and the gaming token with an abnormality in the variable information cannot be identified.

[0066] In contrast, when there is only one RFID tag, as shown in Figure 7B, even when multiple gaming tokens are read at once, the mutual correspondence between the fixed information and variable information read by the reading device can be understood, so it is considered better to implement this using a single RFID tag.

[0067] Furthermore, since the reading accuracy of an RFID tag generally increases the larger the diameter, when an RFID tag is placed in a gaming token, it is desirable that the RFID tag have a diameter at least equal to or greater than the radius of the gaming token, but it is not desirable to place two RFID tags in a gaming token, which would result in the diameter of each RFID tag becoming smaller.Furthermore, placing two RFID tags increases the number of RFID tags to be read, which also leads to a decrease in reading speed when reading multiple gaming tokens.

[0068] For these reasons, it is believed that using a single RFID tag would be more effective.

[0069] (Third embodiment) An overview of the entire table game management system in an amusement parlor having a plurality of gaming tables according to an embodiment of the present invention will be described below. Figure 9 is a diagram showing an overview of the entire system, and the table game management system in an amusement parlor having a plurality of gaming tables 2004 includes a game recording device 2011 that records games played at the gaming tables 2004 as images using a plurality of cameras 2002, including gaming tokens 1, an image analyzing device 2012 that analyzes the recorded images, a chip reading device 25 that reads RFID tags attached to the gaming tokens 1, and a game result determining device 18 that determines and displays the game results of each game at the gaming table 2004.

[0070] The game result determination device 18 is, for example, a card dealing device 2003, which is a so-called electronic shoe already used by those skilled in the art. The rules of the game are pre-programmed, and the device is structured to be able to read the information of the dealt cards C and determine the outcome of the game. For example, in a baccarat game, whether the banker wins, the player wins, or there is a tie (draw) is basically determined by the ranks of two or three cards, and the determination result (win or loss result) is displayed on the result display lamp 2013.

[0071] 9, the gaming table 2004 is a baccarat table and has five sitting numbers 13 ("sitting number 1" 131, "sitting number 2" 132, "sitting number 3" 133, "sitting number 5" 134, and "sitting number 6" 135), allowing five players to participate in the game. A betting area 44 is provided for each sitting number 13. The betting area 44 for each sitting number 13 includes areas for a player (PLAYER) 441, a banker (BANKER) 442, a tie (TIE) 443, a player pair (P) 444, and a banker pair (B) 445. Each player places a bet by placing gaming tokens 1 in the position corresponding to the bet amount. In FIG. 9, for example, two gaming tokens 1 are placed on the tie 443 of sitting number 5, and two on the player 441. The gaming table 2004 is further provided with a player card area 45 where drawn player cards are placed, and a bank card area 46 where drawn bank cards are placed.

[0072] The control device 2014 can grasp, via the camera 2002 and the image analysis device 2012, on which position (player, banker, tie, or pair) each player 2006 has bet their gaming tokens 1 in the betting area 2008, as well as the type and number of gaming tokens 1 bet (different values ​​are assigned to each color of gaming tokens 1). That is, it can grasp, for example, that two coins have been bet on the sitting number 5 tie 443 and two coins on the player 441.

[0073] As shown in FIG. 9, the chip reader 25 is arranged so that it can read all of the RFID tags of the gaming tokens 1 within the reading area, treating the entire betting area for each sitting number as a single reading area. Unique ID information, the amount, type, manufacturing information, and owner information of the gaming token 1 are written to the RFID tag attached to the gaming token 1. Alternatively, the ID information may be stored in a database in association with the amount, type, manufacturing information, and owner information of the gaming token 1. By reading the RFID tag attached to the gaming token 1, the chip reader 25 can identify the gaming tokens 1 for each sitting number and the total amount or number of gaming tokens. For example, if four gaming tokens are bet on sitting number 5, the type, amount, and ID of each gaming token can be identified.

[0074] 10, the control device 2014 ascertains the total amount or total number of gaming tokens 1 for each sitting number from the type and number of gaming tokens 1 bet in each bet area for each sitting number based on the image analysis results by the image analysis device 2012, and compares this with the total amount or total number of gaming tokens 1 for each sitting number based on the RFID information of the gaming tokens 1 read by the chip reader 25, and determines whether they match. Furthermore, it can output sitting numbers for which the above determination does not match, and can identify problematic sitting numbers.

[0075] If the total amount or total number of gaming tokens 1 for each sitting number based on the reading results of the chip reader 25 is less than the total amount or total number of gaming tokens 1 for each sitting number based on the image analysis results of the image analyzer, it is possible that the RFID tags attached to the gaming tokens 1 are broken, the RFID tags are unreadable, or the gaming tokens 1 do not have RFID tags attached. In Figure 10, the total number of readings based on the image analysis results of the image analyzer 2012 for the gaming tokens 1 bet on sitting number 1 is 4, while the total number of readings based on the RFID reading results of the chip reader 25 is 3. Therefore, it is possible that the RFID of one of the four gaming tokens 1 bet on sitting number 1 was unreadable.

[0076] If the total amount or total number of gaming tokens 1 for each sitting number based on the reading results of the chip reader 25 is greater than the total amount or total number of gaming tokens 1 for each sitting number based on the image analysis results by the image analyzer, it is possible that the image analyzer 2012 was unable to read the gaming tokens 1 due to factors such as the gaming tokens 1 being in the camera's blind spot. In Figure 10, the total number of readings based on the image analyzer by the image analyzer 2012 for the gaming token 1 bet on sitting number 3 is 1, while the total number of readings based on the RFID reading by the chip reader 25 is 2. Therefore, it is possible that although two gaming tokens 1 were bet on sitting number 3, the image analyzer was only able to recognize one.

[0077] The RFID ID information attached to the gaming token 1 is registered in the casino's database, which records information on production and shipping at the factory, as well as information on receipt, validation, and activation at the casino. The control device 2014 can compare the RFID information read by the chip reader 25 with the information in the database and determine whether it is authentic or not, and whether it is registered as something that should be used in the casino.

[0078] With this configuration, the camera can grasp the type and number of gaming tokens 1 bet in each betting area, and based on the RFID information of the gaming tokens 1 read by the chip reading device 25, it is possible to determine the authenticity of the gaming tokens 1 for each sitting number as being fraudulent or defective.

[0079] The system further includes a player identification means using a face recognition system or a player ID card, and the control device 2014 can link the player information identified by the player identification means with the sitting number. The control device 2014 can store the bet amount, redemption or recovery amount, and win / loss information stored for each sitting number for each player. Furthermore, the control device 2014 can collectively store information on multiple games played by a player at multiple tables.

[0080] The control device 2014 can determine the total amount of gaming tokens 1 in the chip tray 17 of the dealer 2005 of the gaming table 2004 using the chip tray determination device 12, and after the game is over and settlement is made, can compare and calculate whether the total amount of gaming tokens 1 in the chip tray 17 has increased or decreased according to the outcome of the game, depending on the recovery of the losing gaming tokens 1 bet by each player 2006 and the amount of winning chips 9W paid to the winning player 2006W. The chip tray determination device may determine the total amount of gaming tokens 1 in the chip tray 17 by photographing the gaming tokens 1 stored in the chip tray 17 using the camera 2002 and analyzing the image with an image analyzer, or an RFID reader may be provided in the chip tray 17 to detect the total amount of gaming tokens 1 stored in the chip tray 17.

[0081] In this example, fraud and mistakes are detected based on the outcome of the game, information on how many of what type of gaming tokens 1 were bet and at what position in the betting area 2008 (player, banker, tie, pair), and the increase or decrease in the amount of gaming tokens 1 in the chip tray 17 after the collection of losing chips and the redemption of winning gaming tokens 1 are complete, so fraud and mistakes can be detected without knowing the movement of the gaming tokens 1 after the game ends, i.e., whether the bet gaming tokens 1 moved to the player's side or the dealer's side.

[0082] Here, in the case of baccarat, for example, the outcome of the game can be determined in accordance with the rules of baccarat by reading the rank of card C dealt in the game with the card dealing device 2003. The outcome of the game can also be determined by taking a picture of the gaming table 2004 with the camera 2002, analyzing the image with the image analyzer 2012, and comparing the analysis result with the rules of the game with the control device 2014. In this case, the camera 2002, the image analyzer 2012, and the control device 2014 constitute a game result determination device. Information on the player of each sitting number 7, what type of gaming token 1, and how many coins have been bet on which position (player, banker, tie, player pair, banker pair) in the betting area 2008 can be obtained by taking a picture of the gaming token 1 placed in the betting area 2008 with the camera 2002 and analyzing the image for each playing position 7 with the image analyzer 2012.

[0083] In addition, the increase or decrease in the amount of gaming tokens 1 in the chip tray 17 before and after the collection of losing gaming tokens 1 and the redemption of winning gaming tokens 1 can be calculated by comparing the total amount of gaming tokens 1 in the chip tray 17 before the collection of losing gaming tokens 1 and the redemption of winning gaming tokens 1 with the total amount of gaming tokens 1 in the chip tray 17 after the collection of losing gaming tokens 1 and the redemption of winning gaming tokens 1.

[0084] For example, let us assume that the total amount of gaming tokens 1 on the chip tray 17 before the start of a game is Bb, and that the total amount of gaming tokens 1 on the chip tray 17 after the game is over and the collection of losing chips and the redemption of winning chips is Ba. Also, let us assume that in this game, the total amount of gaming tokens 1 bet on all playing positions 7 in the player area is bp, the total amount of gaming tokens 1 bet on all playing positions 7 in the banker area is bb, and the total amount of gaming tokens 1 bet on all playing positions 7 in the tie area is bt. For example, if the outcome of this game is a win for the banker, then Ba - Bb = bp - bb + bt should be true. Alternatively, the total amount of gaming tokens 1 on the chip tray 17 after the game is over should be (Bb + bp - bb + bt). If this is not the case, it can be determined that fraud or an error occurred in the collection or redemption of the chips.

[0085] FIG. 14A is a diagram showing details of the chip tray of this embodiment, and FIG. 14B is a diagram showing another example of the chip tray. The chip tray 17 is provided with a collection chip tray 171 that collects and temporarily stores gaming tokens 1L bet by a losing player 2006L, and a redemption chip tray 172 that stores gaming tokens 1W to be redeemed. The image analysis device 2012 and the control device 2014 grasp the location, type, and number of gaming tokens 1L bet by the losing player 2006L, and calculate the increase in the gaming tokens 1L for the game (the amount of gaming tokens 1 that should be in the collection chip tray 171). Furthermore, the image analysis device 2012 and the control device 2014 grasp the actual total amount of gaming tokens 1 in the chip tray 171 after collection, and compare the actual total amount with the expected total amount to determine whether there is a difference.

[0086] The control device 2014 further redeems the gaming tokens 1 to be redeemed, and when the redemption is complete, it compares the total amount that should be in the chip tray, which is based on the amount of chips to be redeemed for the game, calculated from the position, type, and number of chips bet by each game participant at the gaming table and the game result, with the actual total amount in the chip tray, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0087] In addition, by using the gaming tokens 1 in the redemption chip tray 172 to redeem the gaming tokens 1W to the winning player 2006W, it is possible to ensure sufficient time for the image analysis device 2012 and the control device 2014 to grasp the actual total amount of the gaming tokens 1 in the collection chip tray 171 after collection.

[0088] As described above, in this embodiment, the control device 2014 calculates the chip balance for each game from the amount of chips bet on the gaming table 2004 and the results of the game, and verifies the increase in the chip balance in the chip tray 17 after the game. If the control device 2014 detects a discrepancy in this verification, it issues an alarm or adds a note to the video recording taken by the camera 2002. The casino operator can investigate the cause of the discrepancy by reviewing the video.

[0089] The table game management system of this embodiment adds or subtracts the increase or decrease in chips in a game, which is calculated from the positions, types, and numbers of gaming tokens 1 bet by all players 2006 in that game and the win / loss result of that game obtained by the win / loss result determination device, from the total amount of gaming tokens 1 in the chip tray 17 before the settlement of each game, and compares the total amount that should be of gaming tokens 1 in the chip tray 17 after settlement at the end of that game with the actual total amount of gaming tokens 1 in the chip tray 17 at the end of that game, obtained via the image analysis device 2012, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0090] The control device 2014 grasps the position, type and number of chips bet by each player via the image analysis device 2012, and when all of the losing chips bet by each player have been collected, grasps the actual total amount of chips in the chip tray, and compares the total amount that should be of gaming tokens 1 in the chip tray 17, which is calculated by adding the increase in the chip tray 17 for that game based on the position, type and number of chips bet by the losing player from the total amount of chips in the chip tray before the settlement of each game, with the actual total amount of gaming tokens 1 in the chip tray 17, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0091] The control device 2014 compares the total amount of gaming tokens 1 that should be in the chip tray 17, which is the total amount of gaming tokens 1 in the chip tray 17 before the settlement of each game, plus the increase in the amount of gaming tokens 1 in the chip tray 17 for that game based on the position, type, and number of gaming tokens 1 bet by the losing player, with the actual total amount of gaming tokens 1 in the chip tray 17, and determines that there is no difference between the total amount that should be and the actual total amount.The control device 2014 also compares the total amount that should be in the chip tray 17 after settlement at the end of that game with the actual total amount of gaming tokens 1 in the chip tray 17 at the end of that game, obtained via the image analysis device 2012, and if it determines that there is a difference between the total amount that should be and the actual total amount, it determines that there is a payment error and generates a payment error signal to notify of the payment error.

[0092] The chip tray 17 is provided with a collection chip tray 171 for collecting and temporarily storing gaming tokens 1 bet by losing players, and the image analysis device 2012 compares the total amount that should be of the gaming tokens 1 in the collection chip tray 171, which is calculated from the position, type and number of gaming tokens 1L bet by the losing player and adds an increase in the amount of gaming tokens 1 for the game in question, with the actual total amount of gaming tokens 1 in the collection chip tray 171, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0093] When the control device 2014 determines that the actual total amount of gaming tokens 1 held in the chip tray 17 of the dealer 2005 at the gaming table 2004 does not correspond to the increase or decrease in the amount of chips calculated from the amount of chips bet by all players and the outcome of the game, the game recording device 2011 can assign an index or time to the captured video, or identify and play back the scene of collecting or paying out the gaming tokens 1, so that the game recording device 2011 can analyze the record of the game in which the above-mentioned difference occurred.

[0094] In this way, the control device 2014 obtains the total amount of chips in the chip tray 17 after settlement at the end of the game via the image analysis device 2012. In this case, the determination after settlement is made when any of the following 1) to 4) occurs. 1) When redemption of winning gaming token 1 is completed, 2) When the card C used in the game is collected and discarded in the discard area 41 or discard slot 42 of the table, 3) When a predetermined button attached to the winning / losing result determination device is pressed, 4) When marker 43, which indicates victory or defeat, is returned to its original position.

[0095] The control device 2014 has an artificial intelligence or deep learning structure that can grasp the positions (positions bet on player, banker, or pair) and amounts (type and number) of chips bet at each playing position 7 of the gaming table 2004, and can extract a unique situation (set by the casino) by comparing the win / loss history of each player 2006 and the amount of chips (winning amount) obtained from the win / loss results of each game with statistical data of many past games (big data). Typically, the control device 2014 has an artificial intelligence or deep learning structure that can extract a unique situation by comparing the occurrence of a winning amount of more than a certain amount (1 million dollars) or a situation in which the amount of bet chips when losing is small and the amount of bet chips when winning is large for several games at a playing position 7 of a certain gaming table 2004 with statistical data (big data, etc.) of past games.

[0096] Furthermore, the control device 2014 of this table game management system (integrated with the image analysis device 2012) is configured to be able to identify individual players 2006 at playing positions 7 who have been extracted as having anomalous circumstances or who have won a predetermined amount or more. To identify such players 2006, the image analysis device 2012 obtains an image of the player's face by extracting feature points or the like, and assigns an identity number (ID, etc.) to the player. When the identified player 2006 leaves his / her seat and takes a seat at another gaming table, the control device 2014 has a warning function that notifies the other gaming table of the presence of the identified player. Specifically, the control device 2014 notifies a pit manager or a person in charge of each table (which may be a dealer) who manages each gaming table 2004, thereby preventing further anomalous phenomena.

[0097] The control device 2014 can identify the collected gaming token 1 for each sitting number based on the RFID ID information of the collected gaming token 1 determined by the chip tray determination device and the RFID ID information of the gaming token 1 read by the chip reading device 25.

[0098] In FIG. 11, gaming tokens 1 are bet as shown in the detailed tables of FIG. 12 and FIG. 13. Analysis by the image analysis device 2012 makes it possible to determine the location (player, banker, etc.) where the gaming tokens 1 are bet, as well as the number (and amount) of gaming tokens. Meanwhile, reading by the chip reading device 25 makes it possible to determine the RFID ID attached to the gaming token 1 for each sitting number. Furthermore, the chip tray determination device 25 can determine the ID of the gaming token 1 in the chip tray 9, and therefore it is possible to determine the collected gaming token 1 by determining the ID that has increased before and after collection. In Figures 11 to 13, if the game result is a win for the banker, the analysis results of the image analysis device 2012 show that the two chips bet on the banker pair should be collected, and of the IDs of the collected chips determined by the chip tray determination device, the two chips with IDs 6 and 18, which the chip reader 25 read as having been bet on sitting number 5, are collected.

[0099] The control device 2014 further grasps the total amount or total number of gaming tokens 1 to be collected for each sitting number, determined using the game results obtained from the game result determination device and the measurement results of the positions, amounts, and numbers of gaming tokens 1 based on the image analysis results by the image analyzer. Therefore, the control device 2014 can compare the total amount or total number of gaming tokens 1 collected for each sitting number, determined based on RFID, with the total amount or total number of gaming tokens 1 to be collected based on the image analysis results, and determine whether they match.

[0100] For example, if the reading result by the chip reading device 25 for sitting number 1 is "A, B, C, D, E," the analysis result by the image analysis device 2012 is "2 chips for tie, 2 chips for banker," the game result is "banker wins," and the reading result by the chip tray determination device 18 is "A, B," it can be determined that the chips A and B bet on tie have been correctly collected.

[0101] The control device 2014 can further determine whether or not the RFID ID information of the collected gaming token 1 determined by the chip tray determination device matches the RFID ID information of the bet gaming token 1 read by the chip reading device 25. This determination makes it possible to determine whether or not the gaming token 1 collected in the chip tray is the gaming token 1 that was bet on the gaming table, or whether or not it is gaming token 1 that was fraudulently collected from another location.

[0102] The control device 2014 can further determine the type of chip, such as a cash chip, rolling chip, or promotional chip, based on the RFID information read by the chip reading device 25, and can store the amount bet and the amount recovered or redeemed for each determined type of chip.

[0103] Rolling chips are special chips that cannot be exchanged for cash and can be purchased by specific members, and the amount purchased by each member is managed. They must be used for betting and consumed, and bets made using rolling chips are redeemed in cash chips. By storing the amount of rolling chips bet or collected based on the RFID information read by the chip reader 25, it is possible to determine the amount of rolling chips that a specific member should have.

[0104] The chip reader 25 further has a function of a confirmation area and is capable of reading the gaming token 1 placed for redemption. As shown in FIG. 15, when redemption is made for the banker sitting number 2, the gaming token 1 for redemption is placed in the chip reader 25 and read. In FIG. 15, the gaming token 1 is placed next to the winning gaming token 1 bet on the banker sitting number 2. The control device 2014 compares the redemption amount determined using the measurement results of the position, amount, and number of the gaming token 1 based on the game result obtained from the game result determination device and the image analysis results by the image analyzer with the amount of the gaming token 1 placed for each sitting number based on the reading result of the chip reader 25, and determines whether the redemption amounts match or do not match, and outputs the result. In FIG. 16, the total number of gaming tokens 1 to be paid for sitting number 1 is 4, but the chip reader 25 reads 3, indicating a mismatch. If the redemption amounts do not match, a mismatch signal is output, and the dealer can replace the gaming tokens 1 for redemption based on the output signal. If the gaming tokens 1 are replaced, a new judgment is made and the judgment result can be output. The area where the gaming tokens 1 for redemption are placed may be anywhere within the chip reader 25. Also, as shown in FIG. 15, a payment confirmation area 26 may be located on the dealer's side of the betting area, separate from the betting area. In FIG. 7, the gaming tokens 1 for redemption are placed in the payment confirmation area 26 for sitting number 6, the chip reader 25 reads them, the control device 2014 makes a judgment, and the redemption chip is placed next to the winning gaming tokens 1 placed by the banker.

[0105] Also, the image analysis device 2012 may perform image analysis on the confirmation area, and the control device 2014 may compare this with the reading result of the chip reading device 25 to determine whether the total number matches.

[0106] The control device 2014 can output a signal based on the determination it has made. The signal may be output to display on the display unit of the chip tray 9 or the display unit of the card dealing device 13, or the signal may be output to a pit manager or the casino backroom.

[0107] The chip reader 25 may treat the entire betting area for each sitting number as one reading area as shown in Fig. 17, or may treat the player betting area and banker betting area as one reading area for each sitting number, and the tie betting area, player pair betting area, and banker pair betting area as one reading area as shown in Fig. 18. Also, as shown in Figs. 19 and 22, the side betting areas of the tie betting area, player pair betting area, and banker pair betting area may each be one reading area.

[0108] The following describes the gaming token 1 used in an embodiment of the present invention. FIG. 20 is an external view of the gaming token 1 used in this system, and FIG. 21 is a front cross-sectional view. A multilayer structure is formed by laminating multiple plastic layers of different colors, with at least a colored layer 101 in the middle, and white layers 102 or light-colored layers (not shown, but which may be lighter in color than the colored layer 101) laminated on both sides of this intermediate colored layer 101. By providing the colored layer 101 and laminating white layers 102 or light-colored layers (not shown, but which may be lighter in color than the colored layer 101) on both sides of this intermediate colored layer 101 in this way, a striped pattern is formed on the side in the stacking direction as shown in FIG. 20, and by changing the color of the colored layer 101 (red, green, yellow, blue, etc.), the type of gaming token 1 (10 points, 20 points, 100 points, 1000 points, etc.) can be identified.

[0109] The colored layer 101 may be formed of a plurality of colored layers (three layers in Fig. 21) as shown in Fig. 21. The plurality of colored layers (three layers in Fig. 21) are thermocompression bonded together, so the three-layer structure is not visible as in Fig. 21, and Fig. 21 shows three layers for the sake of explanation. Furthermore, a cutout B is provided in the middle layer of the three layers of the colored layer 101, and an RFID is embedded within it.

[0110] Furthermore, the gaming token 1 is not limited to a structure in which plastic is laminated, and may have an appearance similar to that of the colored layer 101.

[0111] The method by which the image analyzing device 2012 analyzes the gaming token 1 will be described in detail below. The image analyzing device 2012 analyzes the image recorded in the recording device 11 to recognize at least two colors: a specific color 121 that is at least partially imparted to the gaming token 1, and a reference color R that is different from the specific color 121 and that is present in the image. The specific color 121 is imparted at least partially to the gaming token 1 at a predetermined position or in a predetermined shape. For example, the specific color 121 may be imparted as a colored layer 101, may be imparted circumferentially to the side surface of the gaming token 1, or may be imparted as a predetermined mark on the surface of the gaming token 1. The reference color R may be, for example, the color of a specific area of ​​the gaming table 2004, or may be a color imparted to a location on the gaming token 1 that is different from the specific color 121.

[0112] The image analysis device 2012 includes an artificial intelligence device 12a that identifies a specific color using, for example, deep learning technology, and determines the number and type of gaming tokens 1 placed on the gaming table 2004. The recognition device 12 may further determine the position of the gaming tokens 1 on the gaming table 2004.

[0113] The image analysis device 2012 acquires multiple images of the gaming token 1 and the reference color R illuminated at different illuminances, and learns by manual instruction of the acquired images and the correct colors of the specific color 121 and reference color R of the gaming token 1 in each image as training data, thereby creating a learning model 13a (recognition program). Note that, for images of the gaming token 1 and the reference color R illuminated at the same illuminance conditions, the relative relationship between the specific color 121 and the reference color R can be acquired because the specific color 121 and the reference color R are illuminated at the same illuminance. For example, this relative relationship may be used to recognize the specific color 121.

[0114] Furthermore, the chip recognition device 12 may extract the center line C of the gaming token 1 without using artificial intelligence by measuring image features such as shape, brightness, saturation, and color using the results of image analysis that is performed after the image is photographed and recorded by the camera 200212.

[0115] The artificial intelligence device 12a further has a configuration for analyzing a peripheral image of a predetermined range around the extracted center line C (for example, a range of 8 pixels centered on the center line and perpendicular to the center line), thereby recognizing at least two colors in the peripheral image: the specific color 121 and the reference color R that is different from the specific color 121. When analyzing the peripheral image of a predetermined range around the extracted center line C, the image may be analyzed as is, or may be subjected to image processing such as color enhancement and noise removal to make it easier to recognize the specific color 121.

[0116] In summary, the artificial intelligence device 12a of the recognition device 12 is configured to extract a center line C from an image of the gaming token 1, and perform image analysis of the surrounding images of a predetermined range centered on the center line C, thereby recognizing at least two colors, a specific color 121 in the surrounding image and a reference color R different from the specific color 121, and is an artificial intelligence device that has been taught multiple surrounding images of the gaming token 1 and the reference color R illuminated at different illuminances as training data.

[0120] In the above embodiment, the image analysis device 2012 and the control device 2014 are devices utilizing artificial intelligence or having a deep learning structure. However, the image analysis device 2012 and the control device 2014 may perform image analysis and the above-mentioned various controls using, for example, a Scale-Invariant Feature Transform (SIFT) algorithm, a Convolutional Neural Network (CNN), deep learning, machine learning, or the like. These technologies perform image recognition on captured images to recognize objects contained in the images. In particular, in recent years, deep learning technology, which uses multi-layered neural networks, has been used to recognize objects with high accuracy. This deep learning technology generally recognizes objects with high accuracy by stacking multiple layers in an intermediate layer between the input layer and output layer of a neural network. In this deep learning technology, convolutional neural networks in particular have attracted attention for their superior performance in object recognition compared to conventional methods based on image features.

[0121] A convolutional neural network learns labeled target images and recognizes the main object contained in the target image. If there are multiple main objects in the training image, they are designated by a rectangular area, and the image corresponding to the designated area is labeled for training. Furthermore, the convolutional neural network can determine the main object and its location in the image.

[0122] To further explain convolutional neural networks, the target recognition process involves extracting candidate regions based on local features by performing edge extraction or other processing on the image to be recognized, inputting the candidate regions into the convolutional neural network to extract feature vectors and then classifying them, and obtaining the classified candidate region with the highest confidence as the recognition result. Confidence is a quantity that indicates how high the similarity of the subject of an image learned together with a certain image region and label is relative to the similarity of other classes.

[0161] When one chip reader 25 contains one chip or chip stack to receive a payment, the betting chip and the payment chip can be paired and their owner information can be linked without detecting that the chip has moved outside the area of ​​the chip reader 25. In other words, when one chip reader 25 contains one gaming currency 1001 or one stack of betting chips consisting of several gaming currencies 1001, the betting chip and the payment chip can be paired and their owner information can be linked based on information that the payment chip has disappeared from the chip tray or information that the payment chip has been read by the chip reader 25 on the table, without detecting that the chip has moved outside the area of ​​the chip reader 25. Of course, the betting chip can be recognized based on information that the chip has moved outside the area of ​​the chip reader 25, and the payment chip can be paired with the betting chip using some of information on the chip removed from the chip tray, the chip placed in the betting area, and the chip moved outside the area of ​​the chip reader 25, thereby linking information on the owner of the payment chip based on the owner information of the betting chip. Alternatively, the chip ID may be read by RFID, and the type and number of chips, including stack identification, may be recognized by a camera.

[0162] A single chip or chip stack eligible for payment within a single chip reader 25 includes cases where there was only one chip or chip stack in the area at the time of betting, or cases where there were multiple stacks at the time of betting but the stack was reduced to the last one as payments proceeded. Only the last betting chip stack may be paired with the payment chip and linked to its owner information. In this case, the last remaining stack is designated as the chip bet by the member, ensuring the tracing of the member's chips. It is preferable to allow one member to bet per chip reader (e.g., per player position) while multiple non-members can bet. When there is only one member per player position, the chips are linked to their owner, so the information about the member assigned to each player position can be determined from the information about the bet chips. Furthermore, if a rule requires members to bet before non-members, the first bet chip within a player position may be linked, or confirmed, to the information about the member assigned to that player position (e.g., the member sitting at player position 1). Membership cards may be used to assign members to player positions.

[0163] A chip reader 25 may be provided for each area such as player, banker, tie, pair, etc., or may be provided for each player position, or may divide the entire table into multiple areas such as player positions 1 to 3 and player positions 4 to 6, or may be one large reader 25 for the entire table. In any case, betting chips and payment chips can be paired and owner information, etc. can be updated based on information such as chips being moved out of the area of ​​chip reader 25 (chips being no longer readable by chip reader 25), the ID of a payment chip that has disappeared from the chip tray, and the ID of a payment chip placed in the betting area.
