Description

[0001] Divisional application

[0002] This application is a divisional application of Chinese patent application filed on May 19, 2020, with application number 202010424893.8 and invention title "Management System for Game Currency". Technical Field

[0003] This invention relates to a management system for game coins, which prevents the use of improper game coins in amusement parks or other game facilities that use game coins. Background Technology

[0004] A certain card game exists among several tabletop games played in casinos and other amusement parks. Game coins are used in casinos for playing this game.

[0005] The use of counterfeit game tokens is prohibited in casinos. To prevent the use of counterfeit game tokens in casinos, the following technology exists: RFID tags are attached to game tokens to determine their authenticity, thereby preventing the use of counterfeit tokens. RFID-tagged game tokens are known and disclosed in Patent Document 1 (International Application Publication No. WO2008 / 120749). Summary of the Invention

[0006] In existing gaming token technology, RFID readings can be used to access information written to the storage area and determine the token's authenticity. However, it cannot record and verify information gained during actual use in the casino, particularly information related to the token's owner. Therefore, even if a token is genuine, RFID readings cannot detect instances where the token has been used or exchanged by someone other than its original owner, exhibiting an unusual usage history, nor can they prevent the use of such tokens with abnormal usage records in casinos.

[0007] Therefore, the purpose of this invention is to provide a system that, in order to monitor and manage the owner information of each game coin in real time and improve security, can monitor and record which player the game coin is moved to when the dealer pays the player a game coin and the owner of the game coin moves it from the casino to a player.

[0008] To address the aforementioned problems, the game coin management system of the present invention includes:

[0009] Game tokens, each with an attached RFID tag that can be individually identified;

[0010] A game table used for playing games using the game coins;

[0011] The game coin configuration area, located on the game table, is used to place game coins placed by players participating in the game and to pay game coins from the game coin tray on the game table to the winner;

[0012] A game coin reading device that reads the RFID tags of game coins placed in the game coin configuration area; and

[0013] The control device monitors the reading results from the game coin reading device.

[0014] The control device can obtain information related to the owner of the game coin based on the RFID ID information of the game coin.

[0015] Furthermore, the control device is configured to identify situations where the winner's placed game coins and the game coins paid to the winner move outside the game coin configuration area, and to associate the ID information of the paid game coin and the ID information of the placed game coins that moved outside the game coin configuration area at the same time as the paid game coin in a database.

[0016] Furthermore, it has the following function: in the ID information of the RFID tag containing the game coin, it associates the information related to the owner of the game coin represented by the RFID tag with the database.

[0017] Furthermore, the game coin configuration area is configured to be divided according to each player's position, and includes a PAIR area for placing the payment game coins according to each player's position.

[0018] The game coin reading device can also be configured to distinguish and read the PAIR area according to the position of each player. Attached Figure Description

[0043] (First Implementation)

[0044] use Figure 1 An overview of the desktop game management system according to the first embodiment of the present invention will be described. Figure 1 This is a diagram showing the overall overview of the system. The card game table 1004 has placement areas P1441, B1442, T1443, P.P1444, and B.P1445 arranged according to each player's position 1131-1135. Furthermore, each player's position has a coin placement area 1025, and a coin reading device 1002 is provided to read the RFID of the coins 1001 placed in this coin placement area.

[0045] Furthermore, each game coin configuration area 1025 has a PAIR area 1026, which is used to place the game coins 1001 taken from the game coin tray 1009 when the dealer pays the game coins 1001 from the game coin tray 1009 of the game table 1004 to the winner.

[0046] Furthermore, it also includes a control device 1003, which monitors the RFID reading results of the game coin 1001 read by the game coin reading device 1002.

[0047] At the start of the game, players place game coins 1001 in the designated placement area within the game coin configuration zone. The game coin reader 1002 reads the RFID tag of the placed game coin 1001, thereby enabling the control device 1003 to access information about the owner of the game coin 1001, linked to the RFID tag's ID information, in the database.

[0048] Based on the game's outcome, if the casino wins, the dealer collects the losing player's game coin 1001 and places it in the game coin tray 1009. The game coin reader 1002 monitors the RFID of the game coin 1001 in the game coin tray 1009, and the control device 1003 records the casino's ownership information (the game coin 1001 collected by the casino) in a database.

[0049] Based on the game's outcome, for the winner, the dealer, in accordance with the game's rules, pays the winner an amount of game coins, 1001, from the game coin tray, corresponding to the amount of game coins placed there.

[0050] When making a payment, the game currency can be placed in the aforementioned PAIR area 1026, or it can be placed in a game currency configuration area outside the PAIR area.

[0051] Here, use Figure 2 This section explains the method for recording the owner information of game currency payments. Figure 2 This is a method of recording information related to the owner of game currency 1001 when paying game currency to the winner.

[0052] When multiple players place game coins in the same player's position, creating two or more stacks, the game coin reading device 1002 reads all game coins 1001 placed in the game coin placement area 1025 together. Therefore, during the game, it does not know which game coin 1001 belongs to which player, but obtains the ID 1010 of the placed game coin. After the game's outcome is determined, when paying the winner, the dealer pays each player (per stack) from the game coin tray 1009. The game coins 1001 taken from the game coin tray 1009 are placed in the game coin placement area 1025. The game coin reading device 1002 reads the ID 1011 of the paid game coin placed in the game coin placement area 1025.

[0053] The paid game coin 1001, along with the initially placed game coin 1001, is received by the winner. At this time, the placed game coin and the paid game coin move outside the game coin placement area 1025, and therefore, the IDs of the placed game coin and the paid game coin disappear from the reading results obtained by the game coin reading device 1002. Thus, the control device 1003, by associating with information related to the owner of the placed game coin, knows which player received the paid game coin.

[0054] The control device 1003 associates and stores the information it has about the owner of the game currency and the ID of the game currency in the database.

[0055] Based on the above, the traceability of the owner of game coin 1001 becomes possible. In cases where game coin 1001 is improperly received, it is possible to discover situations where the owner information stored in the database differs from the actual owner.

[0056] In addition, the actual owner can be identified by using facial recognition technology and IDs such as membership cards.

[0057] Furthermore, in the above description, although the IDs of each game coin are managed on the database, it is also possible to have a structure that stores the owner information in the game coin 1001 itself.

[0058] Furthermore, the aforementioned PAIR area 1026 can be configured either according to the position of each player or as an area independent of the position of each player, and can be read independently by the game coin reading device 1002.

[0059] Furthermore, it can also be configured such that, depending on the reading performance of the game coin reading device 1002, one can choose to use the PAIR area 1026 or not use it.

[0060] Furthermore, this desktop game management system can also be configured to combine an RFID reader that reads game coins in the game coin tray 1009 via RFID, a camera that reads the game coins placed therein, a card-dealing shoe that determines the outcome of the game, and other information that is mutually utilized.

[0061] (Second Implementation)

[0062] First, the game currency used in the game currency management system of the embodiments of the present invention will be described. Figure 3 This represents game coin 1 used within the same system. In the same diagram, game coin 1 has an embedded RFID tag 2 capable of storing various information. RFID tag 2 has a non-rewritable data area 21 and a rewritable data area 22.

[0063] Area 21, where data cannot be rewritten, stores information about game token 1 that remains unchanged, unchanging, or immutable during its use as fixed information 3. Specifically, it stores information such as the production information, product information, casino information, amount information, and serial number of game token 1 as fixed information 3. The production information includes the date the game token was manufactured, the manufacturing machine, etc., and the product information includes, for example, information indicating the game token used in the casino's VIP area, information indicating the type of game token (e.g., information indicating it is used as a transcoding code), etc.

[0064] The area 21 where data cannot be rewritten can be a functionally non-writable area or a locked area in the RFID tag design, so that after the necessary information is written in the writable area, no more data can be written.

[0065] It can rewrite data area 22 to store information about changes in game coin 1 during its use as change information 4. For example, such as Figure 3 As shown, information 221 related to date and time, information 222 related to location and event, information 223 related to owner, and other information related to location are stored as change information 4.

[0066] To prevent unauthorized reading and writing of information, fixed information 3 and variable information 4 can be encrypted. Additionally, fixed information 3 and variable information 4 can be stored as metadata.

[0067] Figure 4 This is an example of a method for recording data representing changes in game currency 1. For example... Figure 4 As shown, it is configured such that the information 220 related to the location, consisting of date, time information 221, location, event information 222, and owner information 223, is treated as a block, and the information in this block is linked into a chain, thereby enabling the understanding of the historical record of the information 220 related to the location of the game coin 1.

[0068] exist Figure 4 The diagram illustrates an example of the change information 4 stored in Game Coin 1, allowing us to track the movement of Game Coin 1 as shown below. Mr. A purchased Game Coin 1 at counter 5 at 16:02 on January 28, 2019. Mr. A placed Game Coin 1 at table No. 325 at 16:15 on the same day. Mr. B received Game Coin 1 at table No. 325 at 16:43 on the same day as compensation for winnings from the placement. Mr. B left the casino with Game Coin 1 at 17:01 on the same day.

[0069] like Figure 4 As shown, the change information 4 can be configured to store only the latest information, or it can store all written information related to the current location. Alternatively, several pieces of related information can be selected for storage. When several pieces are selected for storage, multiple pieces of related information can be stored, including at least the latest related information 220 from all related information 220. Based on the above structure, the history of the use or movement of a game coin 1 can be understood based on the change information 4 of that game coin 1. That is, the traceability information of the game coin 1 is configured to be written into the game coin 1 itself and can be monitored.

[0070] The management system for game currency 1 in this embodiment will now be described. Figure 5A summary of the entire system.

[0071] First, in the factory 6, the game coin 1 is written into the rewritable data area 22 of the RFID tag 2 by the writing device 14, which includes change information 4 including information on completion of manufacturing or shipment from the factory as information 220 related to its location.

[0072] The casino's back-end system 7 receives game tokens 1 shipped from factory 6. In back-end system 7, the reading device 13 reads the change information 4 of the rewritable data area 22 stored in the game token 1. Based on the reading result, the management control device 15 determines whether the information 220 related to the location, which should be written, indicating that it has already been written in factory 6, has been written as the latest change information 4. If there is no write record in factory 6, the game token is considered suspicious and an error signal is generated. Therefore, the casino can refuse to accept the game token or request an investigation from the factory. If there is no problem with the write record, the writing device 14 writes the back-end related information 220 into the rewritable data area 22 of the RFID tag 2. During writing, the back-end location information can be added to the factory location information, or the factory location information can be deleted and the back-end location information written. Furthermore, the reading and writing of game tokens in back-end system 7 can be performed simultaneously with the normal verification and activation of game tokens.

[0073] After the game coin 1 has completed its reception and inspection in the background 7, it is moved to the casino's warehouse 8 or counter 9. In warehouse 8 or counter 9, the reading device 13 reads the change information 4 stored in the rewritable data area 22 of the game coin 1. Based on the reading result, the management control device 15 determines whether the information 220 related to the information already written in the background 7, which should be written, has been written as the latest change information 4. Additionally, it can also check whether the information representing factory 6 has been written into the history of change information 4. Similar to the aforementioned check in the background 7, the management control device 15 determines whether there are any anomalies in the history of the information. If the reading result is correct, the writing device 14 writes the relevant information representing warehouse 8 or counter 9 into the rewritable data area 22.

[0074] A player purchases game token 1 at counter 9. Upon purchase, the time of purchase and information indicating the change of ownership (from casino owner to customer) are written as change information 4 via the writing device 14 located at counter 9. Alternatively, the player can be identified and recorded using facial recognition technology, a casino membership card, an ID card, or other similar means.

[0075] Players use purchased game tokens 1, placing them in placement area 11 on the game table to start the game. A reading device 13 reads information 220 from the RFID tag 2 of the placed game token 1, consisting of date, time information 221, location, event information 222, and owner information 223, related to the token's location. The management control device 15 then determines if there are any anomalies. For example, anomalies can be determined if a certain amount of time has passed since the last recorded usage information at the game table or the date of purchase at the counter, or if the owner information 223 stored in the game token 1 differs from the owner information 223 identified through facial recognition or an ID card.

[0076] If the reading result is correct, the writing device 14 adds the associated information 220 to the data-modifying area 22 for the placed game coin 1. The associated information 220 includes date, time information 221, location, event information 222, and owner information 223. At the game table, for example, the writing device 14 writes change information 4, including the player's location number where the game coin 1 is placed and the player's information. The player's information can be determined via ID card or facial recognition. Typically, since several game coins 1 are placed overlapping in the placement area 11, the writing is performed together while they are overlapping.

[0077] When a player takes game token 1 out of the casino, the exit process is completed at entrance / exit 10. During exit, the reading device 14 reads the relevant information 220, and the management control device 15 determines whether the change information 4 is normal. Additionally, at entrance / exit 10, the writing device 14 writes change information 4, including the exit location, event information 222, and owner information 223.

[0078] When a player enters from the casino side, if they bring in game tokens they previously took out, the reading device 13 reads the relevant information, and the management control device determines whether the change information 4 is normal. For example, if the owner of game token 1 temporarily taken out of the casino is different from the owner at the time of departure from the casino, the system can track the receipt of game tokens outside the casino.

[0079] If the reading result from the reading device 13 indicates an anomaly, the management control device 15 can output an alarm to the counter 9 or the entrance / exit 10. When the owner of the game token 1 redeems it at the counter 9 or leaves through the entrance / exit 10, they can refuse redemption based on the alarm output by the management control device 15, or undergo individual checks upon leaving. Furthermore, if the judgment result is abnormal, the management control device 15 can issue a warning to the dealer at each game table to interrupt the game, or issue a warning to the game table manager, who can then determine whether to interrupt the game, continue the game, or replace the game token 1. Alternatively, the management control device 15 can be configured to connect to the overall management control device 18 of the casino and issue a warning to the overall management control device 18.

[0080] Similarly, when exchanging items at the counter, the management control device 15 can use the reading device 13 to read the change information 4 and determine if there is an anomaly. Specifically, an anomaly can be determined in the following situations: a certain amount of time has passed since the last written usage information on the game table or the date of the information exchanged at the counter, and the person attempting to exchange the item is different from the owner information 223 stored in the game coin 1. In the case of an anomaly, the management control device 15 can output a warning and refuse to exchange the game coin 1 that is deemed abnormal.

[0081] Furthermore, although the above description describes a method in which the reading device 13 reads and the writing device 14 writes after the management and control device makes a determination, it is also possible to have a structure in which reading and writing are performed simultaneously.

[0082] The following describes the details of application embodiments of the present invention.

[0083] At factory 6, RFID tags 2 are read and / or written upon completion of production and upon shipment. Production information and product information are written as fixed information 3, locked in a non-rewritable manner as needed, and change information 4 is written.

[0084] In the background 6, the game coin 1 shipped from the factory is received, and when it is activated as a usable game coin 1, the RFID tag 2 is read and / or written.

[0085] In warehouse 8, when game coin 1 is moved from warehouse 8 to counter 9, or from counter 9 to warehouse 8, RFID tag 2 is read and / or written. Alternatively, for game coin 1 stored in warehouse 8, RFID tag 2 can be read and / or written at regular intervals or at specified times.

[0086] At counter 9, RFID tags 2 are read and / or written during movement from or to warehouse 8, and during the exchange of game tokens 1. In the case of an exchange at counter 9, owner information 223, indicating the exchange location, event information 222, and player information, is written as change information 4. Owner information 223 can be obtained using the player's casino ID card, facial recognition system, credit card, etc.

[0087] When players enter and exit through entrance / exit 10, RFID tags 2 are read and / or written. For all game tokens 1 taken out of the casino by players upon exiting, the information indicating the location and event 222 taken out, and the owner information 223 of the player who took them out, are written as change information 4 and registered. Similarly, upon entering, the information indicating the location and event 222 taken in, and the owner information 223 of the player who took them in, are written as change information 4 and the game tokens 1 taken into the casino are registered.

[0088] In placement area 11, RFID tags 2 are read and / or written to game coins 1 placed by players in placement area 11 to participate in the game. Additionally, RFID tags 2 are read and / or written to game coins 1 placed by the dealer in placement area 11 as compensation to players.

[0089] In the game coin tray 12, the RFID tag 2 is read and / or written to the game coins 1 that are returned to the game coin tray and the game coins 1 stored in the game coin tray.

[0090] The game table also has a payment area, which can read and / or write RFID tags 2 to game coins 1 placed in the placement area 11 by the dealer as payment to the players.

[0091] The management and control device 15 has the following function: to determine whether there are any anomalies in the information 220 related to the location obtained from the reading results of the reading device 13 at each location. As a determination of whether it is an anomaly, it can determine whether either the information has not been used for more than a specified time since the last write, or the information related to the location that should have been written has not been written.

[0092] If the data has not been used for a specified period of time since the last write, it falls under any of the following categories.

[0093] 1) The latest relevant information is the information for counter 9, and the next information will be written after a specified period of time;

[0094] 2) The latest relevant information is the entry information at entrance / exit 10. The next information will be written after a specified period of time.

[0095] 3) The latest relevant information is the exit information at entrance / exit 10. The next information will be written after a specified time.

[0096] The failure to write the relevant information that should have been written occurs in any of the following situations:

[0097] 4) When entering the amusement park, the latest information related to the location in area 22, which is the data rewriteable area of ​​game coin 1, is not written, indicating that the player will leave through entrance / exit 10.

[0098] 5) When used at counter 9, information representing backend 7 was not written;

[0099] 6) When leaving the amusement park, information indicating counter 9 or backstage 7 was not written.

[0100] The management control device 15 is capable of determining whether an anomaly is present based on the owner-related information 223 obtained by the reading device 13, using any of the following conditions as a criterion:

[0101] 1) A person who is different from the final owner of the area 22 where the data can be rewritten exchanges game token 1 within the amusement park or leaves the amusement park;

[0102] 2) The game coin is brought into the amusement park by someone who is different from the owner at the time of departure from the area 22 where the data can be rewritten.

[0103] The management control device 15 determines whether an issue is abnormal based on information obtained by the reading device 13 indicating the location of the placement area 11, the location of the game coin tray 12, or the payment area, and makes a judgment on any one of the following conditions 1) to 4):

[0104] 1) The game coin 1 is used at the game table by someone different from the final owner of the area 22 where the data can be rewritten;

[0105] 2) For game token 1 that has no record of being used at the game table, it shall be exchanged at counter 9 by a different person than the one who purchased game token 1 at counter 9;

[0106] 3) Using game token 1 within the amusement park that does not contain information indicating counter 9 or backstage 7;

[0107] 4) The latest relevant information is the information of the placement area 11 or the payment area. After a specified period of time, it can be exchanged at counter 9 or used at the game table.

[0108] Figure 8The database involved in other embodiments of the present invention is shown. In addition to the game coin 1, the management system also includes a database 17 that records the same fixed information 3 and variable information 4. The management control device 15 can record information in the database 17 based on the reading results of the reading device 13, and compare the fixed information 3 and variable information 4 stored in the game coin 1 with the information in the database to determine anomalies.

[0109] In the RFID tag 2 of this embodiment, the area 21 where data cannot be rewritten and cannot be functionally written can be a TID (tag number). After the necessary information is written to the area 21 where data cannot be rewritten, the area locked so that data cannot be rewritten can be an EPC (Electronic Product Code) or a user area. The area 22 where data can be rewritten can be an EPC (Electronic Product Code) or a user area.

[0110] The reading device 13 and the writing device 14 can change their form depending on the location. For example, in factory 6, they can be... Figure 6 The device on the platform shown has a box-shaped entrance / exit 10. The placement area 11 and the coin tray 12 can each function as a reading device 13 and a writing device 14. Furthermore, the coin 1 can be read while directly stacked or stored in a coin box, etc. Additionally, the reading device 13 and the writing device 14 can be integrated into one unit.

[0111] In the above embodiments, the case where the game coin has one RFID tag, and this single RFID tag has areas where data cannot be rewritten and areas where data can be rewritten, has been described. Alternatively, the following configuration can be considered: two RFID tags are placed in the game coin, one of which is locked based on stored fixed information and therefore cannot be rewritten, while the other RFID tag records change information and is therefore pre-set to be rewritable.

[0112] However, in this situation, the following problem arises: when reading multiple game coins together, such as... Figure 7A As shown, since it is possible to read the information group of fixed information 3 and the information group of variable information 4 respectively, it is not possible to determine the combination of fixed information and variable information of a specific game coin, and it is not possible to determine whether there is an abnormal game coin in the variable information.

[0113] In this case, if there is only one RFID tag, such as Figure 7B As shown, even when reading multiple game coins together, it is possible to grasp the correspondence between the fixed and variable information read by the reading device. Therefore, it is believed that it is better to implement this using a single RFID tag.

[0114] Furthermore, generally speaking, the larger the diameter of an RFID tag, the higher the reading accuracy. Therefore, when placing an RFID tag into a game coin, it is desirable for the RFID tag to have a diameter at least equal to the radius of the game coin. However, placing two RFID tags into a game coin results in a smaller diameter for each tag, which is not preferable. Additionally, placing two RFID tags increases the number of RFID tags to be read, thus reducing the reading speed when reading multiple game coins.

[0115] Based on the above, it can be argued that implementing this through a single RFID tag is more effective.

[0116] (Third implementation method)

[0117] The following is a general overview of the management system for tabletop games in an amusement park with multiple game tables according to an embodiment of the present invention. Figure 9 A diagram illustrating the overall structure of the same system shows a management system for tabletop games in an amusement park with multiple game tables 2004, comprising: a game recording device 2011 that records games played at the game tables 2004, including game coins 1, as images via multiple cameras 2002; an image analysis device 2012 that performs image analysis on the recorded images; a game coin reading device 25 that reads the RFID tag attached to the game coin 1; and a game result determination device 18 that determines and displays the game results for each game at the game tables 2004.

[0118] The game result determination device 18 is, for example, a card dealing device 2003, which is a so-called electronic card dealing shoe already used by those skilled in the art. Its construction involves pre-programming the game rules, reading the information of the dealt cards C, and determining the winner of the game. For example, in a certain card game, the win of player B, the win of player P, and a tie (T) are basically determined by the face value of 2-3 cards, and the determination result (win / loss result) is indicated by the result display light 2013.

[0119] In the same diagram, game table 2004 is a table for a card game, with five seats numbered 13 ("Seat No. 1" 131, "Seat No. 2" 132, "Seat No. 3" 133, "Seat No. 5" 134, and "Seat No. 6" 135), allowing five players to participate. Each seat number 13 has a placement area 44. Placement areas 44 for seat number 13 include areas for P (PLAYER) 441, B (BANKER) 442, T (TIE) 443, P.P 444, and B.P 445. Each player plays the game by placing a certain amount of game coins (1) in the corresponding positions. Figure 9For example, two game coins (1) are placed at seat number 5, T443, and two game coins (1) are placed at seat number 5, P441, to start the game. The game table 2004 also includes a P-family card area 45 for placing drawn P-family cards and a B-family card area 46 for placing drawn B-family cards.

[0120] The control device 2014, with the aid of the camera 2002 and the image analysis device 2012, can determine the location (P, B, T, PAIR) of each player 2006 in the placement area 2008, the type of game coin 1 placed (game coins 1 are divided into different values ​​according to each color), and the number of coins placed. That is, for example, it can determine that 2 coins were placed in seat 5, T443, and 2 coins were placed in P441.

[0121] like Figure 9 As shown, the game coin reading device 25 is configured to read the RFID tags of game coins 1 within each seat number, treating the entire placement area as a single reading area. The RFID tags attached to game coins 1 contain inherent ID information, the amount, type, manufacturing information, and owner information of the game coins 1. Alternatively, the ID information can be stored in a database in association with the amount, type, manufacturing information, and owner information of the game coins 1. By reading the RFID tags attached to the game coins 1, the game coin reading device 25 can identify game coins 1 for each seat number, thereby identifying the total amount or number of coins. For example, it can identify that four game coins are placed at seat number 5, along with their respective types, amounts, and IDs.

[0122] like Figure 10 As shown, the control device 2014, based on the image analysis results of the image analysis device 2012, determines the total amount or total number of game coins 1 for each seat number according to the type and quantity of game coins 1 placed in each placement area of ​​each seat number. This is compared with the total amount or total number of game coins 1 for each seat number obtained based on the RFID information of the game coins 1 read by the game coin reading device 25, to determine if they are consistent. Furthermore, it can output the seat numbers determined to be inconsistent, thus identifying problematic seat numbers.

[0123] If the total amount or number of game coins 1 for each seat number obtained from the reading results of the game coin reading device 25 is less than the total amount or number of game coins 1 for each seat number obtained from the image analysis results of the image analysis device, it is considered that there may be a situation where the RFID attached to the game coin 1 is damaged, is an unreadable RFID, or the game coin 1 is not attached to an RFID. Figure 10In the above scenario, for game coin 1 placed at seat number 1, the total number of reads obtained by the image analysis device 2012 is 4, while the total number of reads obtained by the RFID reader 25 is 3. Therefore, it is considered that the RFID of one of the four game coins 1 placed at seat number 1 cannot be read.

[0124] If the total amount or number of game coins 1 for each seat number obtained from the reading results of the game coin reading device 25 is greater than the total amount or number of game coins 1 for each seat number obtained from the image analysis results of the image analysis device, it is considered that there may be a situation where the image analysis device 2012 cannot read the game coin 1 due to reasons such as the game coin 1 entering the blind spot of the camera. Figure 10 In the example, for game token 1 placed at seat number 3, the total number of reads obtained by the image analysis device 2012 is 1, while the total number of reads obtained by the RFID reader 25 is 2. Therefore, it is possible that there are 2 game tokens 1 placed at seat number 3, but the image analysis device can only identify 1.

[0125] The RFID ID information attached to game token 1 is registered in the casino's database, which also records information on production and shipment at the factory, as well as receipt, verification, and activation at the casino. Control device 2014 compares the RFID information read by game token reader 25 with the information in the database to determine the authenticity of the game token registered as a token to be used in the casino.

[0126] According to this structure, the type and number of game coins 1 placed in each placement area can be determined by the camera, and the game coin reading device 25 can determine whether the game coin 1 is fake or defective for each seat number based on the RFID information of the game coin 1.

[0127] In addition, the tabletop game management system also includes a participant identification mechanism using a facial recognition system or player ID cards. The control device 2014 can associate the participant information identified by the participant identification mechanism with the seat number. The control device 2014 can store, for each participant and seat number, the amount placed, the amount repaid or recovered, and win / loss information. Furthermore, it can simultaneously store information about multiple games played by participants at multiple game tables.

[0128] The control device 2014 can use the coin tray determining device 12 to determine the total amount of game coins 1 in the coin tray 17 of the dealer 2005 at the game table 2004. After the game ends and settlement is completed, the control device 2014 can compare and calculate whether the total amount of game coins 1 in the coin tray 17 has been increased or decreased based on the amount of game coins 1 lost by each player 2006 and the amount of game coins 90,000 won by the winning player 2006. The coin tray determining device can be configured to use the camera 2002 to photograph the game coins 1 stored in the coin tray 17 and analyze the image to determine the total amount of game coins 1 in the coin tray 17. Alternatively, it can be configured to use an RFID reader installed in the coin tray 17 to detect the total amount of game coins 1 stored in the coin tray 17.

[0129] In this example, since cheating and errors can be detected based on the outcome of the game, the information on which type and number of game coins 1 were placed in the placement area 2008 (P, B, T, or PAIR), and the increase or decrease in the amount of game coins 1 in the game coin tray 17 after the recovery of lost game coins and the repayment of won game coins 1, cheating and errors can be detected even without knowing the movement of game coins 1 after the game ends, i.e., whether the placed game coins 1 moved to the player's side or to the dealer's side.

[0130] For example, in the case of a card game, the card dispensing device 2003 reads the face value of the card C drawn in the game, and the winner can be determined according to the rules of the card game. Alternatively, the camera 2002 captures an image of the game table 2004, the image analysis device 2012 analyzes the image, and the control device 2014 compares the analysis results with the game rules to determine the winner. In this case, the camera 2002, the image analysis device 2012, and the control device 2014 constitute the game result determination device. Information about which position (P, B, T, PP, BP) and what type of game coin 1 each player at seat number 7 placed in the placement area 2008 can be obtained by using the camera 2002 to capture an image of the game coin 1 placed in the placement area 2008, and then analyzing the image by the image analysis device 2012 for each playing position 7.

[0131] Furthermore, the increase or decrease in the amount of game coins 1 in the game coin tray 17 before and after the recycling of lost game coins 1 and the repayment of won game coins 1 can be calculated as follows: the total amount of game coins 1 in the game coin tray 17 before the recycling of lost game coins 1 and the repayment of won game coins 1 is compared with the total amount of game coins 1 in the game coin tray 17 after the recycling of lost game coins 1 and the repayment of won game coins 1.

[0132] For example, the total amount of game coins 1 in the game coin tray 17 before the game starts is set as Bb, and the total amount of game coins 1 in the game coin tray 17 after the game ends, including the recovery of lost game coins 1 and the repayment of won game coins 1, is set as Ba. Furthermore, in this game, the total amount of all play positions 7 of game coins 1 placed in area P is set as bp, the total amount of all play positions 7 of game coins 1 placed in area B is set as bb, and the total amount of all play positions 7 of game coins 1 placed in area T is set as bt. For example, if the game results in a win for player B, Ba - Bb = bp - bb + bt should hold true. Alternatively, the total amount Ba of game coins 1 in the game coin tray 17 after the game ends should be (Bb + bp - bb + bt). If the above conditions are not met, it can be determined that there is cheating or error in the recovery or repayment of game coins.

[0133] exist Figure 14A The middle section is a detailed diagram showing the game coin tray of this embodiment. Figure 14B This diagram illustrates another example of a game coin tray. The game coin tray 17 includes: a recycling tray 171, which recycles and temporarily holds the game coins 1L placed by the losing player 2006L; and a return tray 172, which holds the returned game coins 1W. The image analysis device 2012 and the control device 2014 determine the location, type, and number of game coins 1L placed by the losing player 2006L, and calculate the increase in game coins 1L during the game (the expected amount of game coins 1L in the recycling tray 171). Furthermore, the image analysis device 2012 and the control device 2014 determine the actual total amount of game coins 1L in the recycled tray 171, compare the expected total amount with the actual total amount, and determine if there is a discrepancy.

[0134] Furthermore, the control device 2014 is able to repay the corresponding game coins 1, and at the end of the repayment, compare the total amount due on the game coin tray based on the amount due on the game coins in the game with the actual total amount on the game coin tray, and determine whether there is a difference between the total amount due and the actual total amount. The amount due on the game coins in the game is calculated based on the position, type and number of game coins placed by each game participant on the game table, and the game result.

[0135] Furthermore, by repaying the winning player's 2006W game coins 1W, sufficient time is ensured that the image analysis device 2012 and the control device 2014 have sufficient time to grasp the actual total amount of game coins 1L in the recovered game coin tray 171 by using the game coin 1W in the recovery game coin tray 172.

[0136] As described above, in this embodiment, the control device 2014 calculates the income and expenditure of game coins based on the amount of game coins placed on the game table 2004 and the winning or losing result of the game, and verifies the increase in the balance in the game coin tray 17 after the game. If a discrepancy is detected in this verification, the control device 2014 issues a warning or adds a record indicating the detected discrepancy to the recording of the video captured by the camera 2002. The casino operator can investigate the cause of the discrepancy by reviewing the video.

[0137] In the tabletop game management system of this embodiment, the total amount of game coins 1 in the game coin tray 17 before each game settlement is added to or subtracted from the amount of increase or decrease in game coins in the game calculated based on the position, type, and number of game coins 1 placed by all players 2006 in the game and the win or loss result of the game obtained by the win or loss result determination device. The system then compares the expected total amount of game coins 1 in the game coin tray 17 after the settlement at the end of the game with the actual total amount of game coins 1 in the game coin tray 17 at the end of the game obtained by means of the image analysis device 2012, and determines whether there is a difference between the expected total amount and the actual total amount.

[0138] The control device 2014, with the aid of the image analysis device 2012, grasps the position, type, and number of game coins placed by each player. After all the lost game coins placed by each player are collected, the control device 2014 grasps the actual total amount of game coins in the game coin tray. The control device 2014 compares the expected total amount of game coins 1 in the game coin tray 17 with the actual total amount of game coins 1 in the game coin tray 17 and determines whether there is a difference between the expected total amount and the actual total amount. The expected total amount of game coins 1 in the game coin tray 17 is obtained by adding the total amount in the game coin tray before the settlement of each game to the increase in the game coin tray 17 in the game based on the position, type, and number of game coins placed by the losing players.

[0139] The control device 2014 compares the total amount of game coins 1 in the game coin tray 17 before each game settlement with the additional amount of game coins 1 in the game coin tray 17 obtained by adding the amount of game coins 1 placed by the losing player according to the position, type and number of game coins 1 in the game. If it is determined that there is no difference between the total amount and the actual amount, the control device 2014 compares the total amount of game coins 1 in the game coin tray 17 after the game ends with the actual amount of game coins 1 in the game coin tray 17 obtained by means of the image analysis device 2012. If it is determined that there is a difference between the total amount and the actual amount, it determines that there is a payment error and generates a payment error signal to notify of the payment error.

[0140] The game coin tray 17 is equipped with a game coin recycling tray 171, which collects and temporarily stores the game coins 1L placed by the losing player. The image analysis device 2012 compares the expected total amount of game coins 1L in the game coin recycling tray 171 with the actual total amount of game coins 1L in the game coin recycling tray 171, and determines whether there is a difference between the expected total amount and the actual total amount. The expected total amount of game coins 1L in the game coin recycling tray 171 is obtained by adding the increase of game coins 1 in the game based on the position, type and number of game coins 1L placed by the losing player. When the control device 2014 determines that there is a discrepancy between the actual total amount of game coins 1 held in the game coin tray 17 of the dealer 2005 at the game table 2004 and the increase or decrease of game coins calculated based on the amount of game coins placed by all players and the winning or losing result of the game, in order to analyze the game record that caused the above discrepancy in the game recording device 2011, the game recording device 2011 can assign an index or time to the obtained image, or determine and recreate the recycling scene or payment scene of game coins 1.

[0141] Thus, the control device 2014 obtains the total amount of game coins in the game coin tray 17 after the game ends, using the image analysis device 2012. However, the determination of "after settlement" in this case refers to the moment when any of the following 1) to 4) occurs:

[0142] 1) The repayment of the won game coins 1 ends;

[0143] 2) When the card C used in the game is recycled and discarded in the discard area 41 or discard slit 42 of the table;

[0144] 3) When the designated button attached to the win / loss result determination device is pressed;

[0145] 4) The symbol indicating win or loss 43 is restored.

[0146] Furthermore, the control device 2014 is constructed using artificial intelligence or deep learning: it can grasp the position (position of P, B, or PAIR) and amount (type and number) of game coins placed at each play position 7 of the game table 2004, and compare the win / loss history and the amount of game coins won by each player 2006 obtained from the win / loss results of each game with the statistical data of a large number of past (big data) games to extract anomalies (set by the casino). Typically, the device 2014 is constructed using artificial intelligence or deep learning: if a winning amount of more than a certain amount (1 million points) occurs, or if the amount of game coins placed when losing is less than the amount placed when winning is more in a certain play position 7 of the game table 2004 continues in multiple games, this situation can be compared with the statistical data of past games (big data, etc.) to extract this as an anomaly.

[0147] Furthermore, the control device 2014 (integrated with the image analysis device 2012) of the management system for this tabletop game is configured to identify individual players 2006 at playing positions 7 where abnormal situations have been detected, or at playing positions 7 where a player has won a specified amount or more. For the identification of such players 2006, the image analysis device 2012 obtains a facial image through feature point extraction, etc., and assigns it an identification number (ID, etc.). Moreover, the control device 2014 has a warning function that notifies the other table of the presence of a specific player 2006 when the player leaves and sits at another table. Specifically, it notifies the game table manager or the person in charge of each table (or the dealer) of the game tables 2004 to prevent further abnormalities.

[0148] The control device 2014 can determine the number of game coins 1 collected per seat number based on the RFID ID information of the collected game coin 1 determined by the game coin tray determination device and the RFID ID information of the game coin 1 read by the game coin reading device 25.

[0149] exist Figure 11 In, such as Figure 12 as well as Figure 13 As shown in the detailed table, game token 1 is placed. Based on the analysis of the image analysis device 2012, the location (P, B, etc.) and number (and amount) of game token 1 can be determined. On the other hand, based on the reading of the game token reader 25, the RFID ID attached to the game token 1 for each seat number can be determined. Furthermore, since the game token tray determining device 25 can determine the ID of the game token 1 within the game token tray 17, it can determine the IDs added before and after recycling, thereby determining the recycled game token 1. Figures 11-13In the case where B wins the game, according to the analysis results of the image analysis device 2012, it can be determined that the two game coins placed on BP should be recycled. It can also be determined that the two game coins ID6 and ID18 placed on seat number 5 are recycled according to the ID of the game coin tray determination device and the game coin reading device 25.

[0150] Furthermore, the control device 2014 can determine the total amount or number of game coins 1 to be recovered for each seat number, based on the game results obtained by the game result determination device and the detection results of the position, amount, and number of game coins 1 obtained based on the image analysis results obtained by the image analysis device. Therefore, the control device 2014 can compare the total amount or number of game coins 1 recovered for each seat number determined based on RFID with the total amount or number of game coins 1 to be recovered based on the image analysis results, and determine whether they are consistent.

[0151] For example, if the reading result of the game coin reading device 25 for seat number 1 is "A, B, C, D, E", the analysis result of the image analysis device 2012 is "T 2 coins, B 2 coins", the game result is "B wins", and the reading result of the game coin tray determination device 18 is "A, B", it can be known that the game coins A and B placed in T have been correctly collected.

[0152] Furthermore, the control device 2014 can determine whether the RFID ID information of the game coin 1 recovered by the game coin tray determining device matches the RFID ID information of the game coin 1 placed by the game coin reading device 25. Based on this determination, it can be determined whether the game coin 1 recovered by the game coin tray is the game coin placed on the game table, or whether it is the game coin 1 improperly recovered from other locations.

[0153] Furthermore, the control device 2014 can determine the type of game currency, such as transcoded or promotional codes, based on the RFID information read by the game currency reader 25, and can store the amount placed, the amount redeemed, or the amount refunded for each determined type of game currency.

[0154] Transcodes are special game tokens that specific members can purchase but cannot exchange. Transcodes are managed according to the amount purchased by each member. By storing the amount of transcodes placed or retrieved based on RFID information read by the game token reader 25, it is possible to know the amount of transcodes that a specific member should hold.

[0155] The game coin reader 25 also has a region verification function and can read the game coins 1 placed for repayment. For example... Figure 15As shown, when repaying the debt to family B at seat number 2, game coin 1 for repayment is placed in the game coin reading device 25 and read. Figure 15 In the middle, the winning game coin 1 is placed next to the one placed at seat number 2 (B). The control device 2014 can compare the repayment amount determined based on the game results obtained from the game result determination device and the image analysis results obtained from the image analysis device (based on the measurement results of the position, amount, and number of game coins 1), with the amount of game coins 1 placed for each seat number obtained based on the reading results of the game coin reading device 25, and determine and output whether the repayment amount is consistent. Figure 16 In the case of seat number 1, the total number of game coins 1 payable is 4, while the game coin reading device 25 reads 3, indicating a discrepancy. In the event of a discrepancy in the repayment amount, a discrepancy signal is output, allowing the dealer to reposition the game coins 1 used for repayment based on the output signal. Upon repositioning the game coins 1, a second judgment is made, and the judgment result is output. The area where the game coins 1 used for repayment are placed can be any location within the game coin reading device 25. Additionally, as... Figure 15 As shown, the payment confirmation area 26 can be configured separately from the placement area on the dealer's side of the placement area. Figure 15 In the process, the game coin 1 used for repayment is placed in the payment confirmation area 26 of seat number 6. The game coin reading device 25 reads the coin, and the control device 2014 makes a judgment. The repayment game coin is then placed next to the winning game coin 1 placed in B's house.

[0156] In addition, the image analysis device 2012 also performs image analysis on the confirmed area, and the control device 2014 compares it with the reading result of the game coin reading device 25 to determine whether the total number of coins is consistent.

[0157] The control device 2014 can output signals based on the implemented decision. The signals can be output by displaying them on the display unit of the coin tray 17 or the display unit of the card dispensing device 13, or by the game table manager or the casino's back office.

[0158] Game coin reader 25 can be like Figure 17 As shown, all placement areas are treated as one read area for each seat number, or as follows: Figure 18 As shown, for each seat, the placement area for P and the placement area for B are combined into one reading area, and the placement area for T, the placement area for P, and the placement area for B are combined into another reading area. Additionally, as... Figure 19 and Figure 22As shown, the side placement areas of the TP, PP, and BP placement areas can also be used as a single reading area.

[0159] Next, the game coin 1 used in the embodiments of the present invention will be described. Figure 20 This is the appearance image of the game coin 1 used in this system. Figure 21 This is a front sectional view. The game coin 1 is formed with the following multi-layered structure: multiple plastic layers of different colors are stacked, with a colored layer 101 at least in the middle. White layers 102 or light-colored layers (not shown, but any layer lighter than the colored layer 101) are stacked on both sides of the colored layer 101. This multi-layered structure, with a colored layer 101 and white layers 102 or light-colored layers (not shown, but any layer lighter than the colored layer 101) stacked on both sides of the colored layer 101, thus... Figure 20 As shown, a striped pattern with overlapping direction is formed on the side. By changing the color of the coloring layer 101 (red, green, yellow, blue, etc.), the type of game coin 1 (10 points, 20 points, 100 points, 1000 points, etc.) can be determined.

[0160] Shading layer 101 can also be like Figure 21 As shown, through multiple colored layers (in) Figure 21 It is formed by three layers. Due to the multiple layers that are colored (in... Figure 21 The middle layer consists of 3 layers that are heat-pressed together, therefore, as Figure 21 As shown, the three-layer structure is not visually perceptible. Figure 21 The description indicates three layers. Furthermore, a portion of the cutout B is provided in the middle layer of the three colored layers 101, where an RFID tag is concealed.

[0161] In addition, the game coin 1 is not limited to the structure of the laminated plastic layer, but can also be a structure with the same appearance as the coloring layer 101.

[0162] The method by which the image analysis device 2012 analyzes the game coin 1 is described in detail below. The image analysis device 2012 performs image analysis on the image recorded by the recording device 11, identifying at least two colors: a specific color 121 at least partially attached to the game coin 1, and a reference color R present in the image that is different from the specific color 121. Furthermore, the specific color 121 is attached to a predetermined location on the game coin 1 or at least partially attached to the game coin 1 in a predetermined shape. For example, it can be attached as a coloring layer 101, attached circumferentially to the side of the game coin 1, or attached as a predetermined mark to the surface of the game coin 1. In addition, the reference color R can be, for example, the color of a specific area of ​​the game table 2004, or a color attached to the game coin 1 at a different location than the specific color 121.

[0163] Image analysis device 2012 includes, for example, an artificial intelligence device 12a that determines specific colors using deep learning technology, and determines the number and type of game coins 1 arranged on the game table 2004. Image analysis device 2012 can also determine the position of game coins 1 on the game table 2004.

[0164] The image analysis device 2012 acquires multiple images of the game coin 1 and the reference color R illuminated under different illumination levels. Through manual instruction, it uses the acquired images and the correct colors of the game coin 1's specific color 121 and the reference color R in each image as teacher data to learn and create a learning model 13a (recognition program). Furthermore, for images of the game coin 1 and the reference color R illuminated under the same illumination conditions, it can obtain the relative relationship between the specific color 121 and the reference color R by illuminating them under the same illumination. For example, this relative relationship can be used for the recognition of the specific color 121.

[0165] Furthermore, the image analysis device 2012 can also extract the center line C of the game coin 1 by taking pictures and recording them as images using the camera 2002, without using artificial intelligence, and by using the results of image analysis to detect features on the image such as shape, brightness, color saturation, and hue.

[0166] The artificial intelligence device 12a also has the following structure: by performing image analysis on a peripheral image of a predetermined range around the extracted center line C (e.g., a range of 8 pixels orthogonal to the center line), it identifies at least two colors in the peripheral image, namely the specific color 121 and the reference color R, which is different from the specific color 121. Furthermore, when performing image analysis on the peripheral image of the predetermined range around the extracted center line C, the image can be analyzed directly, or it can be analyzed after image processing such as color enhancement and noise removal, to more easily identify the specific color 121.

[0167] In summary, the artificial intelligence device 12a of the image analysis device 2012 has the following features: extracting the center line C from the image of the game coin 1; performing image analysis on the surrounding images within a predetermined range centered on the center line C; identifying the structure of at least two colors in the surrounding images, namely a specific color 121 and a reference color R different from the specific color 121; and teaching multiple surrounding images of the game coin 1 and the reference color R illuminated under different illuminations as teacher data.

[0168] In other embodiments of the present invention, the control device 2014 further includes the function of determining at least one of the following:

[0169] 1) In each game, from the time the starting cards are drawn or from the start of the dealer's game until the game's outcome is displayed by the card-distributing device, are there any changes in the game currency?

[0170] 2) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, were there any changes in the game coins caused by anyone other than the dealer?

[0171] 3) After each game ends, during the period when the dealer is collecting the game coins placed by the losers among the game participants, are additional game coins added?

[0172] 4) After each game, did the dealer pay out the winning coins placed by the participants?

[0173] 5) After each game, did the winner among the game participants take the game coins that were placed and the game coins that were paid out?

[0174] Furthermore, the control device 2014 can also be configured to detect the movement of the dealer's and game participants' hands, the movement of game coins, or the movement of the hands and the movement of game coins by using the analysis results of the image analysis device, thereby determining at least one of 1) to 5).

[0175] The control device 2014, according to the rules of a certain card game, has the functions shown in 1) to 5) below, which are characteristic functions of this invention, determining whether cheating that violates the rules has not occurred. That is,

[0176] 1) In each game, the image analysis device 2012 uses information obtained from the camera 2002 to monitor whether there is any change in game coin 1 from the signal of drawing the starting card obtained from the card dispensing device 2003, or from the start operation of the game initiated by the dealer 2005 pressing the start button for 4 seconds, until the game result is displayed by the card dispensing device 2003.

[0177] 2) After each game ends, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the loser 6 has taken the game coin 1 without cheating during the period when the dealer 2005 is collecting the game coin 1 placed by the loser among the game participants 2006.

[0178] 3) After each game ends, the image analysis device 2012 uses the information obtained from the camera 2002 to monitor whether anyone other than the dealer 2005 (winner or loser) added the won game coin 1W, or whether they did not replace the game coin 1 on the winning side that was not placed, during the period when the dealer 2005 was collecting the game coin 1 placed by the loser among the game participants.

[0179] 4) After each game, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the dealer 2005 placed the game coin 1 in the position of the winner among the game participants 2006, and correctly placed the game coin 1W to be paid.

[0180] 5) After each game ends (the dealer 2005 operates the card dispensing device 2003 and displays the winning and losing results on the indicator light 13), the image analysis device 2012 uses the information obtained from the camera 2002 to monitor whether the winner 6W among the game participants 2006 has taken the placed game coin 1 and the game coin 1W that has been paid out.

[0181] Furthermore, in the above embodiments, the image analysis device 2012 and the control device 2014 are devices with artificial intelligence-efficient or deep learning structures. Specifically, the image analysis device 2012 and the control device 2014 can be scale-invariant feature transform (SIFT) algorithms, convolutional neural networks (CNNs), deep learning, machine learning, or perform image analysis and control using the same methods. These techniques are for image recognition of camera images to identify objects contained within the images. In particular, in recent years, deep learning techniques that utilize multi-layered neural networks have been used to identify objects with high accuracy. This deep learning technique generally achieves high-accuracy object recognition by overlapping layers across multiple stages in the intermediate layers between the input and output layers of the neural network. Among these deep learning techniques, convolutional neural networks, in particular, have attracted attention because they have higher performance than object recognition based on existing image feature quantities.

[0182] In convolutional neural networks (CNNs), labeled images of target objects are learned, and the main objects included in these images are identified. When multiple main objects exist within the learning image, they are designated using rectangular regions, and labels are added to the images corresponding to these designated regions for learning. Furthermore, the CNN can then determine the main objects within the image and their locations.

[0183] To further explain convolutional neural networks, in the object recognition process, edge extraction and other processing are performed on the image of the object to be recognized. Based on local features, candidate regions are extracted. These candidate regions are then input into the convolutional neural network, and classification is performed based on the extracted feature vectors. The candidate region with the highest confidence level is obtained as the recognition result. Confidence level refers to how much higher the similarity between a given image region and the main body of the image learned along with the label is compared to other levels of similarity.

[0184] The above describes various embodiments of the present invention. However, those skilled in the art can certainly modify the above embodiments within the scope of the present invention, and the device of this embodiment can be appropriately modified according to the needs of the applicable game.

[0219] Furthermore, the information contained in the RFID tag can be encrypted.

[0220] Furthermore, the area where data cannot be rewritten can be a structure that cannot functionally rewrite data, or a structure that is locked to prevent data rewriting.

[0221] Furthermore, the reading device is configured to simultaneously read the fixed information stored in the area where the data cannot be modified, and the related information stored in the area where the data can be modified;

[0222] The management and control device can be configured to extract and grasp the relevant information of the area where the data can be rewritten in the same RFID tag from the fixed information of the multiple game coins read by the reading device.

[0223] To address the aforementioned problems, the game coin of the present invention comprises a single RFID tag having both a region where data cannot be rewritten and a region where data can be rewritten.

[0224] The area where data cannot be rewritten stores at least one of the following as fixed information: the game coin's production information, product information, casino information, amount information, and serial number.

[0225] The area capable of rewriting data is configured to store the information related to the location of the game coin, written by the writing device, as change information.

[0226] It is possible to extract, from the fixed information stored in the area where the data can be rewritten, the change information stored in the same RFID tag.

[0227] Furthermore, the game coin can be structured as follows: a reading device can read the fixed information stored in the area of ​​the non-rewritable data of multiple game coins, and based on the read fixed information, can read the related information stored in the area of ​​the rewritable data.

[0228] To address the aforementioned problems, the desktop game management system of the present invention includes:

[0229] Game tokens, each with an attached RFID tag that can be individually identified;

[0230] A game table used for playing games using the game coins;

[0231] A game recording device that uses a camera to record images of game coins placed by each player during a game at the arcade table;

[0232] An image analysis device that performs image analysis on the recorded image of the game coin;

[0233] A game coin reading device that reads the RFID tags attached to the game coins placed by each game participant; and

[0234] The control device monitors the image analysis results from the image analysis device and the reading results from the game coin reading device.

[0235] The game table has multiple placement areas, and each seat number includes at least a placement area for seat P and a placement area for seat B.

[0236] The game coin reading device reads the game coins by treating all placement areas as a single reading area for each seat number, or by dividing the entire area into fewer reading areas than the number of placement areas, and reading the game coins for each of the aforementioned reading areas.

[0237] The control device has the following structure: based on the image analysis results of the image analysis device, it can independently determine the type and number of game coins placed in each placement area, including at least the P placement area and the B placement area; it can determine whether the total amount or total number of game coins for each seat number or each reading area obtained based on the image analysis results of the image analysis device is consistent with the total amount or total number of game coins for each seat number or each reading area obtained based on the reading results of the game coin reading device; and it outputs the determination result.

[0238] Furthermore, the control device can be a structure capable of outputting seat numbers that do not conform to the determination results.

[0239] The control device may also have the following structure: when the total amount or number of game coins for each seat number obtained based on the reading result of the game coin reading device is less than the total amount or number of game coins for each seat number obtained based on the image analysis result of the image analysis device, a signal can be generated indicating that the RFID attached to the game coin may be damaged, or that the game coin may not have an RFID attached.

[0240] Furthermore, the control device may also have the following structure: if the total amount or number of game coins for each seat number obtained based on the reading result of the game coin reading device is greater than the total amount or number of game coins for each seat number obtained based on the image analysis result of the image analysis device, a signal may be generated indicating that the image analysis device may have made an error in reading the game coins.

[0241] In addition, it has a database that stores the IDs of the RFID tags attached to the game tokens.

[0242] The control device can have the following structure: it can compare the RFID ID obtained from the reading result of the game coin reading device with the ID stored in the database to determine the authenticity of the game coin and output the determination result.

[0243] In addition, it also has,

[0244] A coin tray that holds the coins used by the dealer at the game table;

[0245] A game coin tray detection device, capable of determining the type and quantity of game coins stored in the game coin tray; and

[0246] The game result determination device determines the game results of each game on each game table.

[0247] The control device has the following calculation function: using the game results obtained by the game result determination device and the determination results of the position, amount and number of game coins obtained based on the image analysis results of the image analysis device, the income and expenditure of the entertainment side of the game table are calculated according to the recycling and repayment of each game.

[0248] It can also have:

[0249] The coin recycling judgment function compares the amount of coins to be recycled with the actual amount recycled from the coin tray at the end of the recycling process for each player. It determines if there is a discrepancy between the expected and actual amount recycled, thereby identifying any cheating or error in the coin recycling process. The expected amount of coins to be recycled is calculated based on the position, type, and number of coins placed by each player on the game table, and the game results.

[0250] The repayment determination function repays the corresponding game coins. At the end of the repayment, it compares the total amount due to be repaid based on the game coins in the game with the actual total amount of the game coin tray. If there is a difference between the total amount due and the actual total, it is determined that there is cheating or error in the repayment. The amount due to be repaid for the game coins in the game is calculated based on the position, type, and number of game coins placed by each game participant on the game table and the game result.

[0251] Furthermore, the control device can have the following structure:

[0252] The system can determine the ID information of the recovered game coin based on the RFID of the game coin determined by the game coin tray determination device, and the RFID of the game coin read by the game coin reading device.

[0253] The system uses ID information to determine the game coins to be recycled for each seat number. It compares the determined ID, amount, or number of game coins with the ID, amount, or number of game coins to be recycled for each seat number, and determines whether they match for each seat number. The ID, amount, or number of game coins to be recycled for each seat number is determined using the measurement results of the position, amount, and number of game coins obtained based on the game results obtained by the game result determination device and the image analysis results obtained by the image analysis device.

[0254] Furthermore, the control device can be structured as follows: in each game, it can determine the type of game coin based on the RFID ID information of the game coin read by the game coin reading device, according to the purpose or use of the game coin, and store the amount, or the amount to be recovered or the amount to be repaid for each type of game coin according to each seat number.

[0255] Furthermore, the control device can be structured such that, in multiple games, it can store, for each seat number, the cumulative amount placed, the cumulative amount recovered, or the cumulative amount repaid for each type of game coin.

[0256] In addition, the game currency can be at least a transcode or a promotional code.

[0257] In addition, the control device can be structured as follows: it can determine the owner based on the ID information of the transcoded data, and store the cumulative amount of the transcoded data, or the cumulative amount of the recovered data, or the cumulative amount of the repaid data for each owner.

[0258] In addition, the game coin reading device reads the game coins placed in the device for repayment according to each seat number.

[0259] The control device may have the following structure: it compares the repayment amount determined based on the game result obtained by the game result determination device and the image analysis result obtained by the image analysis device, which determines the position, amount and number of game coins, with the amount of game coins placed according to each seat number obtained based on the reading result of the game coin reading device, and determines and outputs whether the repayment amount is consistent or inconsistent.

[0260] Furthermore, the control device can be structured as follows: if the determination result of the repayment amount is inconsistent, it can display inconsistency; and if the amount of game coins placed in the game coin reading device for each seat number changes, it can make a determination again and output consistency or inconsistency again.

[0261] Furthermore, the control device can be structured as follows: capable of comparing the amount of game coins placed for repayment according to each seat number, and the increase or decrease in the amount of game coins in the tray before and after repayment, to determine whether there is a difference.

[0262] In addition, the game coin reading device may have a payment confirmation area located on the dealer's side of the placement area for placing the game coins used for repayment.

[0263] In addition, it can also be equipped with a system for identifying game participants using facial recognition or player ID cards.

[0264] The control device may be a structure capable of associating the seat number with information about the game participants determined by the game participant determination agency.

[0265] In addition, it also includes a display device that displays the output of the control device.

[0266] In addition, the game table also has a side-mounted placement area.

[0267] The side placement area is arranged adjacent to each placement area for each seat number.

[0268] The game coin reading device can read at least one of the side placement areas simultaneously.

[0269] The control device can have the following structure: based on the image analysis results of the image analysis device, it can determine the type and number of game coins placed in the at least one side placement area, and determine whether the total amount or total number of game coins in the at least one side placement area obtained based on the image analysis results of the image analysis device is consistent with the total amount or total number of game coins in the side placement area obtained based on the reading results of the game coin reading device, and output a signal of the determination result.

[0270] Furthermore, other embodiments of the present invention include a desktop game management system, as follows.

[0271] It has the following characteristics:

[0272] Game tokens, each with an attached RFID tag that can be individually identified;

[0273] A game table used for playing games using the game coins;

[0274] A game recording device that uses a camera to record images of game coins placed by each player during a game at the arcade table;

[0275] An image analysis device that performs image analysis on the recorded image of the game coin;

[0276] A game coin reading device that reads the RFID tags attached to the game coins placed by each game participant; and

[0277] The control device monitors the image analysis results from the image analysis device and the reading results from the game coin reading device.

[0278] The game table has a placement area consisting of a P-placement area, a B-placement area, and a side-placement area.

[0279] The side placement area is arranged adjacent to each placement area for each seat number.

[0280] The game coin reading device can read at least one of the side placement areas simultaneously.

[0281] The control device has the following structure: based on the image analysis results of the image analysis device, it can independently determine the type and number of game coins placed in the at least one side placement area, determine whether the total amount or total number of game coins in the at least one side placement area obtained based on the image analysis results of the image analysis device is consistent with the total amount or total number of game coins placed on that side obtained based on the reading results of the game coin reading device, and output the determination result signal.

[0282] Furthermore, the control device can be a side-mounted structure capable of outputting inconsistent determination results.

[0283] Furthermore, the control device may also have the following structure: when the total amount or number of game coins placed on each side obtained based on the reading result of the game coin reading device is less than the total amount or number of game coins placed on each side obtained based on the image analysis result of the image analysis device, a signal may be generated indicating that the RFID attached to the game coin may be damaged, or that the game coin may not have an RFID attached.

[0284] Furthermore, the control device may also have the following structure: if the total amount or number of game coins in each of the side placement areas obtained based on the reading result of the game coin reading device is greater than the total amount or number of game coins in each of the side placement areas obtained based on the image analysis result of the image analysis device, a signal may be generated indicating that there may be a reading error of the game coins by the image analysis device.

[0285] In addition, it also has a database that stores the IDs of the RFID tags attached to the game tokens.

[0286] The control device can have the following structure: it can compare the RFID ID obtained from the reading result of the game coin reading device with the ID stored in the database to determine the authenticity of the game coin.

[0287] Furthermore, the control device can be structured as follows: it can determine the number of game coins collected in each side-placed area based on the RFID ID information of the collected game coins determined by the game coin tray determination device and the RFID ID information of the game coins read by the game coin reading device; it compares the ID, amount, or number of game coins to be collected in each side-placed area with the ID, amount, or number of game coins collected in each side-placed area, and determines whether the collected amount is consistent or inconsistent for each side-placed area. The determination of the ID, amount, or number of game coins to be collected in each side-placed area is obtained by using the measurement results of the game coin position, amount, and number of game coins obtained based on the game result obtained by the game result determination device and the image analysis result obtained by the image analysis device.

[0288] If a single coin or a stack of coins is to be paid within the area of ​​a coin reader 25, the placed coin and the paid coin can be paired and associated with owner information without detecting that the coin has been moved out of the area of ​​the coin reader 25. That is, even if a single coin or a stack of multiple coins 1001 exists within the area of ​​the coin reader 25, the owner information can be linked to the paid coin based on information that the paid coin has disappeared from the coin tray or information that the coin has been read by the coin reader 25 on the table. Alternatively, the placed coin can be identified based on information that it has been moved out of the area of ​​the coin reader 25, and the placed coin and the paid coin can be paired using information from the coin removed from the coin tray, the coin placed in the placement area, and the coin moved out of the area of ​​the coin reader 25, thereby associating the owner information of the paid coin with the owner information based on the owner information of the placed coin. Alternatively, the ID of the game tokens can be read via RFID, and the type, quantity, and stack of game tokens can be identified by a camera.

[0289] In a coin reader 25, the presence of a coin or stack of coins to be paid for in an area includes not only cases where a coin or stack of coins was already present in the area when the coin was placed, but also cases where multiple stacks of coins were present when the coin was placed, but only one stack remained during the payment process. The remaining stack of coins can be paired with the payment coin to be associated with the owner's information. In this case, by treating the remaining stack of coins as coins placed by a member, tracking the member's coins can be ensured. Preferably, for each coin reader (e.g., each player position), only one member player is allowed to place coins, while multiple non-member players are allowed to place coins. With one member player at each player position, since the coins and owners are linked, the information of the member player assigned to each player position can be determined based on the information of the placed coins. Furthermore, if there are rules stipulating that member players should place coins before non-member players, the first placed coin can be associated with the information of the member player assigned to the player position (e.g., sitting in player position 1), or this association can be confirmed. Membership cards can be used to assign member players to player positions.

[0290] The coin reader 25 can be set up for each area such as P, B, T, PAIR, etc., or a larger coin reader 25 can be set up for each player position, for each divided area, or for the entire table. The divided area is formed by dividing the entire table into multiple areas, such as an area including player positions 1 to 3 and an area including player positions 4 to 6. In any case, the owner information can be updated by matching placed and paid coins based on information such as the area where coins have been removed from the coin reader 25 (no longer read by the coin reader 25), the ID of paid coins that have disappeared from the coin tray, and the ID of paid coins placed in the placement area.
