[0002] Cross-referencing of related applications This application claims the benefit of Japanese Patent Application No. 2020-128081, filed on July 29, 2020, the contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to a management system for gaming supplies equipped with RFID tags. Background Technology

[0004] Gaming equipment used in casinos is known to include those equipped with RFID tags. These RFID tags store identification information, and a database stores the identification information of valid gaming equipment. In the casino, security is ensured by reading the RFID tag of the gaming equipment and referring to the database to determine whether the equipment is genuine.

[0005] RFID tags have a TID (Tag Identifier) ​​area and an EPC (Electronic Product Code) area as storage areas. Each area enables the RFID tag to store its inherent tag identification information, as well as the game items using the RFID tag to store their inherent item identification information.

[0006] When reading RFID tags, one can compare them using only the item identification information, or one can compare them using both the tag identification information and the item identification information. The former allows for reading and comparison in a shorter time, but the level of security is lower. On the other hand, the latter requires a longer time for reading and comparison, but the level of security is higher (e.g., International Application Publication No. WO2008 / 120749). Summary of the Invention

[0007] The problem that the invention aims to solve The purpose of this invention is to provide a new technology for achieving the security of gaming products by using tag identification information and product identification information.

The management system comprises: an RFID reader that reads the identification information from the RFID tags of the game items located within the reading range; and a control device that controls the RFID reader. The control device causes the RFID reader to repeatedly perform a first read that reads the product identification information without reading the tag identification information. If new product identification information is read in the first read, the RFID reader is then caused to perform a second read that reads the tag identification information.

[0009] According to this structure, when RFID tags are repeatedly read by an RFID reader, it is usually set to identify the information of newly read RFID tags while reading the identification information of the item. Therefore, it can shorten the reading time and ensure a high level of security.

[0010] In the aforementioned management system, the control device causes the RFID reader to perform a second read on the game item for which the item identification information was newly read in the first read.

[0011] In the aforementioned management system, the control device can determine, based on the number of item identification information read in the first reading and the number of newly read item identification information, whether to have the RFID reading device perform the second reading on all the game items or only on the game items for which the item identification information has been newly read.

[0012] In the aforementioned management system, during the second reading of a game item for which the item identification information was newly read in the first reading, the control device can specify the newly read item identification information and read the tag information of the game item.

Detailed Implementation

[0053] The management system of the present invention will now be described with reference to the accompanying drawings. However, the invention is not intended to be limited by the following embodiments, and the constituent elements in the following embodiments include elements that are readily conceived by those skilled in the art or are substantially the same.

[0054] The following explanation uses game currency as an example of game items, but game items can also be items other than game currency. For example, it can be a shuffled card pack containing multiple shuffled game cards. Furthermore, game items do not have to be items that circulate within the casino like game currency, nor do they have to be items that are consumed in large quantities and discarded in the casino like a shuffled card pack.

[0055] Figure 1 The diagram illustrates the manufacturing and use process of game supplies according to embodiments of the present invention. Figure 2 This is a perspective view showing game coins, which are game supplies used as embodiments of the present invention. For example... Figure 2 As shown, the side of the game coin 72 displays a pattern indicating its value, and a decal 723 is affixed to the center of its surface and back, the decal 723 indicating the price of the game coin 72. Furthermore, the game coin 72 has a built-in RFID tag 721.

[0056] like Figure 1 As shown, the game coin manufacturing plant 200, acting as the manufacturer of game coins, purchases RFID tags 721 from the RFID tag manufacturing plant 100, uses these RFID tags to manufacture game coins 72 with built-in RFID tags 721, and supplies them to the casino 300. In the casino 300, game coins 72 with built-in RFID tags 721 are purchased from the game coin manufacturing plant 200, and games using game coins 72 are operated in the game pool 302.

[0057] Figure 3 A diagram illustrating the information stored in the RFID tag of a game coin according to an embodiment of the present invention. (See diagram) Figure 3 As shown, the RFID tag 721 includes the following areas as storage areas: a TID area 211 storing tag identification information attached by the manufacturer of the RFID tag 721 (RFID tag factory 100), and an EPC area 212 storing item identification information attached by the manufacturer of the game coin 72, which has the RFID tag 721 embedded in it (game coin manufacturing factory 200). In the TID area 211, the tag identification information is stored by the RFID tag manufacturing factory 100 that manufactures the RFID tag 721, and in the EPC area 212, the item identification information is stored by the game coin manufacturing factory 200 that manufactures the game coin 72.

[0058] In TID area 211, the RFID tag 721 stores a unique tag ID as tag identification information. In EPC area 212, the game coin 72 stores a unique game coin ID as item identification information. Furthermore, in addition to the game coin ID, EPC area 212 stores the game coin's attributes and value (10 points, 100 points, 1000 points, etc.) as category information, the manufacturing plant ID used to identify the manufacturing plant of the game coin 72 and the manufacturing date of the game coin 72 as manufacturing information, the casino ID used to identify the casino using the game coin 72, and further, the activation status ("valid" or "invalid") and its update time and date as activation information. It should be noted that at the time the game coin manufacturing plant 200 manufactures the game coin 72, the activation status is "invalid".

[0059] It should be noted that the activation status can be represented by a conditional branch (Flag). In this case, it can be interpreted as "valid" when the condition is met, and "invalid" or "not valid" when the condition is not met. Furthermore, some or all of the category information, manufacturing information, casino ID, game coin ID (item identification information), and activation information may not be stored in EPC area 212, but rather in the unshown user area of ​​RFID tag 721.

[0060] In the game coin manufacturing plant 200, to manufacture game coins 72 with built-in RFID tags 721, firstly, RFID tags 721 are manufactured in the RFID tag manufacturing plant 100. At this time, tag identification information for identifying the RFID tag 721 is written into the TID area 211 of the RFID tag 72. The RFID tags 72 manufactured in the RFID tag manufacturing plant 100 are provided to the game coin manufacturing plant 200. In the game coin manufacturing plant 200, game coins 72 with built-in RFID tags 721 are manufactured. Furthermore, in the game coin manufacturing plant 200, the game coin ID and other information (see reference) are written into the EPC area 212 of the RFID tag 721. Figure 3 ).

[0061] In the coin manufacturing plant 200, parallel to the manufacturing of coin 72, a data file 73 is prepared that records a combination of tag ID and coin ID (hereinafter, tag ID and coin ID are collectively referred to as "identification information"). While providing the manufactured coin 72 to the casino 300, the coin manufacturing plant 200 also provides the data file 73 to the casino 300 through a different means. It should be noted that the data file 73 can be sent to the casino 300 by the coin manufacturer via email, or it can be recorded by the coin manufacturer on a removable storage medium and given to the casino 300, or it can be stored by the coin manufacturer in a cloud storage device and then downloaded by the casino 300. At this time, the data file 73 is provided to the casino 300 by the coin manufacturing plant 200 in an encrypted state using an appropriate method.

[0062] Casino 300 has a back office 301 that players 74 cannot access, and a game pool 302 for players 74 to play games. The back office 301 includes: a warehouse 31 for storing game items, including game coins 72; a processing room 32 for activating game coins 72; and a cashier's room 33 and a bank room 34 connected to the game pool 302.

[0063] The cashier's room 33 has a window that connects to the game pool 302. In the cashier's room 33, game coins 72 are given to players 74 in the game pool 302 in order to purchase game coins with cash. That is, players 74 can purchase game coins 72 with cash through the window of the cashier's room 33.

[0064] The bank room 34 and the game table 35 are used for replenishing and depositing game coins 72. Replenishment refers to supplying game coins 72 from the bank room 34 to the game table 35 when the supply of game coins 72 to the game table 36 is insufficient. Deposit refers to returning game coins 72 from the game table 35 to the bank room 34 when there are sufficient game coins 72. Therefore, the bank room 34 is equipped with a passage or window for depositing and retrieving game coins 72 between itself and the game pool 302.

[0065] Game coins 72 supplied from the game coin manufacturing plant 200 to the casino 300 are first stored in warehouse 31 of the back office 301. In the processing room 32, the game coins 72 stored in warehouse 31 undergo an activation procedure. After activation, the game coins 72 are taken to the game pool 302 via cashier's room 33 or bank room 34. It should be noted that once activated, the game coins 72 are stored in warehouse 31, they can be provided from warehouse 31 to cashier's room 33 or bank room 34.

[0066] Player 74 can purchase game coins 72 at the cashier's room 33 or at the game table 36. Player 74 places game coins 72 in the game at the game table 36. If the player wins the game, they receive a refund of game coins 72 from the dealer 75. If the player loses the game, the placed game coins 72 are taken back by the dealer 75. Thus, the number of game coins 72 held by the dealer 75 at the game table 36 increases or decreases with the games played. If there are insufficient game coins 72 on the game table 36, they are replenished from the game table 35. If there is a surplus of game coins 72 on the game table 36, they are moved from the game table 36 to the game table 35. Furthermore, player 74 can enter and exit the game pool 302 via entrance 38. Depending on the casino, it may be permitted to carry game coins 72 directly into and out of the game pool 302.

[0067] The warehouse 31, processing room 32, cashier's room 33, bank room 34, various game tables 35, various game desks 36, and entrance / exit 38 in the casino 300 are all places for processing game coins 72 as game supplies.

The electronic card shoe 36c is equipped with a sensor for detecting game cards drawn by the dealer and detecting information about at least the face value of the game card. The electronic card shoe 36c is connected to the game table comparison device 363 and notifies the game table comparison device 363 that the first game card in the game has been drawn.

[0076] Specifically, the electronic card shoe 36c has a button operated by the dealer 75 at the end or beginning of the game, which controls whether the game ends or begins. Furthermore, the electronic card shoe 36c determines the end of the game according to the game rules by reading the face value of the drawn cards. Additionally, when the electronic card shoe 36c detects that the initial game card has been drawn after the game has ended or begun, it outputs a signal to the game table matching device 363 notifying the game table of the end.

[0077] The game table system 360 includes: an antenna 361a and a coin tray reader / writer 362a, which is mounted on the coin tray 36a for reading the RFID tags 721 of the coins 72 stored in the coin tray; antennas 361b1 to 361b6 (collectively referred to as "antenna 361b") and coin reader / writers 362b, which are respectively disposed in the placement areas 36b1 to 36b6 of the game table 36 for reading the RFID tags 721 of the coins 72 placed in the placement areas of the game table 36.

[0078] The game table system 360 also includes: a game table matching device 363, which uses information read by the coin tray reader 362a and the coin placement reader 362b to match the game coin 72; and a game table storage device 364, which stores the information read by the coin tray reader 362a and the coin placement reader 362b. It should be noted that the entrance / exit 38 may also have the same entrance / exit system as the aforementioned subsystems.

[0079] (activation) The activation procedure performed in the processing room 32 is described below. Game coins 72 manufactured in the game coin manufacturing factory 200 are brought to the back office 301 of the casino 300 and stored in the warehouse 31. In the processing room 32, the game coins 72 stored in the warehouse 31 are retrieved, and the activation procedure for the game coins 72 is performed using the processing room system 320.

[0080] The processing room system 320 has a data file 73 containing identification information provided by the game coin manufacturing plant 200 (the manufacturer of game coins 72). The processing room system 320 receives this data file 73 using an input device 324. Since the data file 73 is encrypted, the input device 324 decrypts it. It should be noted that, in addition to identification information, the data file 73 may also record some or all of the other information stored in the RFID tag 721 of each game coin 72 (see reference). Figure 3 ).

[0081] Antenna 321 and Activation Reader 322 read the tag ID and game coin ID, which serve as identification information, from the RFID tag 721 of the game coin 72 to be activated. Registration device 325 determines whether the game coin 72 is a genuine game coin officially manufactured by game coin manufacturer 200, a counterfeit game coin not officially manufactured by game coin manufacturer 200, or a game coin with a malfunctioning RFID tag 721, by comparing the identification information stored in the RFID tag 721 of the game coin 72 with the identification information stored in the data file 73. In other words, registration device 325 determines the authenticity of game coin 72 based on whether the identification information stored in the RFID tag 721 of the game coin 72 matches the identification information stored in the data file 73.

[0082] If the registration device 325 determines that the game coin 72 is genuine during the authenticity check, it records its identification information (tag ID and game coin ID) in the database 326, thereby registering the game coin 72. At this time, if other information such as manufacturing information is recorded on the RFID tag 721 and / or data file 73 of the game coin 72, this information is also recorded in the database 326 in association with the identification information. Furthermore, the registration device 325 records the activation information of each game coin 72 in the database 326.

[0083] Figure 6 This diagram illustrates the data structure of the database recording information for each game coin in an embodiment of the present invention. In this embodiment, for each game coin 72, the database 326 records the following information: a tag ID as tag identification information 261, attributes and value as category information 262, a manufacturing factory ID and manufacturing date as manufacturing information 263, a game coin ID and game coin symbol ID as game coin identification information 264, activation status and update time and date as activation information 265, and a historical record of the combination of location and read time and date as location historical record information 266.

[0084] When the registration device 325 registers a game coin 72 that has been successfully matched and determined to be genuine into the database 326, it records the status of its activation information 265 as "valid" and records the time and date at that time as the update time and date, thereby activating (validating) the game coin 72 as a usable game coin. Thus, by referring to the database 326, it is possible to determine whether the activation status of each game coin 72 is "valid" or "invalid," and also to know when it was activated (when it was registered).

[0085] In this embodiment, the EPC area 212 of the RFID 721 of the game coin 72 also records activation information. Therefore, the registration device 325, as the registration process for usable game coins 72, controls the writing function of the activation reader 322, thereby changing the activation status recorded in the RFID tag 721 of the game coin 72 that has been successfully matched and determined to be genuine from "invalid" to "valid" via the antenna 321. Thus, the systems 330-360 at each game item processing location can know whether the activation status of the game coin 72 is "valid" or "invalid" simply by reading the RFID tag 721 of the game coin 72.

[0086] As described above, game token 70 is invalid until it is activated by the processing room system 320 after being transported from the game token manufacturing plant 200 to the casino 300. Therefore, even if game token 72 is stolen during the transfer process, the stolen game token 72 cannot be used in the game pool 302 of the casino 300. The casino only needs to strictly manage the game token 72 after it has been activated, which improves security and reduces security costs compared to having to strictly manage it from the game token 72 manufacturing stage.

[0087] (Comparison of game item processing locations) In the cashier's room 33, bank room 34, game table 35, and game table 36, which serve as game item processing locations, the cashier system 330, bank system 340, game table system 350, and game table system 360, respectively, are used to verify the identification information and confirm the activation status of the game coins 72 to be processed at that location. The following is a description of each game item processing location.

[0088] In the cashier's room 33, the antenna 331 of the cashier system 330 and the cashier reader 332 read the RFID tag 721 of the game coin 72 stored in the cashier's room 33 to obtain the tag ID, game coin ID, and activation status. In addition to its comparison function, the cashier verification device 333 also functions as a control device to control the reading and writing of the cashier reader 332. First, if the cashier verification device 333 reads an "invalid" activation status from the RFID tag 721 of the game coin 72, it outputs an error signal indicating this status. Upon outputting an error signal, the cashier's room 33 stops processing the game coin 72.

[0089] The cashier verification device 333 also sends the identification information (tag ID and game coin ID) obtained by the cashier reader 332 to the processing room system 320. The central verification device 323 of the processing room 330 checks whether the identification information received from the cashier system 330 is stored in the database 326, and confirms whether the activation status associated with the identification information is valid.

[0090] When the corresponding identification information is stored in database 326 (i.e., it is a genuine game coin) and the activation state is valid, the central comparison device 323 sends a response signal indicating that the game coin 72 is a genuine game coin and is valid to the cashier system 330. On the other hand, if the game coin 72 being compared is not a genuine game coin, the central comparison device 323 sends an error signal indicating that it is not a genuine game coin to the cashier system 330 as a response signal. Even if the game coin 72 being compared is a genuine game coin, but the activation state is invalid, an error signal indicating that it is a genuine game coin but invalid will be sent to the cashier system 330 as a response signal.

[0091] It should be noted that if the activation status of a game coin 72 read from the RFID tag 721 of the game coin 72 is valid in the cashier comparison device 333, but the database 326 records the activation status as invalid, the cashier comparison device 333 determines that the game coin 72 is counterfeit and controls the writing function of the cashier reader 332 to rewrite the activation status of the RFID tag 721 of the game coin 72 to "invalid" via the antenna 331. Alternatively, the cashier comparison device 33 can rewrite the activation status to "unknown".

[0092] Furthermore, if a record in database 326 shows an activation status of "valid," but the activation status read from the RFID tag 721 of the game coin 72 in the cashier's comparison device 333 is "invalid," it is determined that the activation status of the RFID tag 721 of the game coin 72 has been overwritten for some reason. The activation status of the RFID tag 721 of the game coin 72 can be overwritten to "valid." Alternatively, the activation status of the game coin 72 can be overwritten to "invalid" or "unknown," and its processing can be terminated.

[0093] For game tokens 72 brought directly from the processing room 32 or via the warehouse 31 to the cashier's room 33, the possibility of counterfeit or illegitimate game tokens is low since they have already been activated in the processing room 32. However, for game tokens 72 brought in by users from the game pool 302 and exchanged between game tokens, counterfeit or illegitimate game tokens 72 may exist. Therefore, in particular, for game tokens 72 involved in game token exchanges, the cashier's verification device 333 can verify the identification information and confirm the activation status, and present the results to the player 74 and the cashier staff. Alternatively, when the player 74 purchases game tokens 72, the device can read the value information stored in the RFID tag 721 of the game token 72 and present this information to the player 74, while simultaneously verifying the identification information and confirming the activation status, and presenting the results along with the value information to the player 74.

[0094] For game coins 72 brought in by users from game pool 302 and exchanged between game coins (bringing in game coins, buying game coins), the cashier verification device 333 reads the tag ID and game coin ID from the RFID tag 721 of the game coin 72 and sends them to the central verification device 323 for verification. When player 74 purchases game coins 72, for game coins 72 handed over to player 74 (taking out game coins), the cashier verification device 333 reads only the game coin ID from its RFID tag 721 and sends it to the central verification device 323 for verification. Thus, the cashier verification device 333 determines whether to use only the game coin ID for verification or to verify both the tag ID and the game coin ID, depending on whether the processed game coin 72 is a game coin brought in or a game coin taken out.

[0095] It should be noted that in this embodiment, in the cashier system 330, the combination of one antenna 331 and the cashier reader 332 can read both incoming and outgoing game coins. The operator (the staff in the cashier room 33) specifies to the cashier comparison device 333 whether the game coin 72 to be read is an incoming game coin or an outgoing game coin. The cashier comparison device 333 receives this specification and controls the cashier reader 332 to determine whether to read only the game coin ID or to read both the tag ID and the game coin ID.

[0096] Antenna 331 is divided into antennas for bringing in game coins and antennas for taking out game coins. When a cashier reader 332 uses these antennas 331, the cashier reader 332 specifies which antenna 331 to use according to the instructions from the cashier matching device 333.

[0097] Alternatively, the combination of antenna 331 and cashier reader 332 can be used for both bringing in and taking out game coins. In this case, the cashier matching device 333 determines which combination of antenna 331 and cashier reader 332 to use based on instructions from the operator.

[0098] Furthermore, separate cashier systems 330 for taking in game currency and 330 for taking out game currency can be set up. In this case, the cashier system 330 for taking in game currency is configured to read the tag ID and the game currency ID, while the cashier system 330 for taking out game currency is configured to read the game currency ID without reading the tag ID.

[0099] The bank system 340 essentially performs the same operations as the teller system 330. The replenished game tokens 72 are moved from the bank room 34 to the game table 35 in the game pool 302. These game tokens 72 are activated in the processing room 32, making it difficult to consider them counterfeit or improperly funded. However, for game tokens 72 brought from the game pool 302 to the bank room 34 during deposit, including those temporarily given to players 74 and then collected by the dealer, counterfeit or improperly funded game tokens 72 may be mixed in. Therefore, in particular, the bank system 340 can verify the identification information and activation status of game tokens 72 brought from the game pool 302.

[0100] The bank system 340 can also function similarly to the teller system 330. Specifically, the bank verification device 343 reads the tag ID and game coin ID from the RFID tags 721 of the game coins 72 brought in from the game pool 302 (bringing in game coins, depositing game coins) and compares them. For game coins 72 brought out from the bank room 340 to the game pool (taking out game coins, replenishing game coins), it reads the game coin ID instead of the tag ID and only uses the game coin ID for comparison. In addition to its verification function, the bank verification device 343 also functions as a control device for reading and writing in the bank reader / writer 342.

[0101] Furthermore, the banking system 340 can also be divided into a banking system 340 for bringing in game currency and a banking system 340 for taking out game currency. In this case, the banking system 340 for bringing in game currency reads the tag ID and game currency ID from the brought-in game currency and compares them, while the banking system 340 for taking out game currency only reads the game currency ID from the taken-out game currency and does not read the tag ID for comparison.

[0102] The game table system 350 essentially performs the same operations as the cashier system 330. Game table 35 receives game coins 72 replenished from the bank 34, as well as excess game coins 72 on the game table 36. The game table system 350 compares the game coins 72 received into game table 35 in this manner. Furthermore, excess game coins 72 on game table 35 are moved to the bank 34 (deposited), or if game coins 72 are insufficient on game table 36, game coins 72 are replenished from game table 35 to game table 36. The game table system 350 also compares the game coins 72 removed from game table 35 in this manner.

[0103] The game table system 350 can be the same as the cashier system 330 and the bank system 340. That is, for game coins 72 brought in from the game table 36, the game table matching device 353 reads the tag ID and game coin ID from the RFID tags 721 of these game coins and compares them. For other game coins 72, it reads the game coin ID but not the tag ID, and only uses the game coin ID for comparison. In addition to the comparison function, the game table matching device 353 also functions as a control device to control the reading and writing of the game table reader 352.

[0104] The operation of the game table system 360 is as follows. In the game table 36, the dealer 75 returns game coins 72 from the game coin tray 36a to the winning player 74. An antenna 361a is mounted on the game coin tray 36a, and a game coin tray reader 362a reads identification information and activation status from the RFID tags 721 of the game coins 72 stored in the game coin tray 36a. The identification information read by the game coin tray reader 362a is compared with the game table comparison device 363 and stored in the game table storage device 364. When multiple game coins 72 are stored in the game coin tray, the game table storage device 364 stores multiple identification information corresponding to the multiple game coins 72.

[0105] In addition to its comparison function, the game table comparison device 363 also functions as a control device to read and write to the coin tray reader / writer 362a and the coin placement reader / writer 362b, and to store information in the game table storage device 364. The game table comparison device 363 first compares the latest past identification information stored in the game table storage device 364 with the current identification information read by the coin tray reader / writer 362a, and determines whether the two are consistent.

[0106] If the identification information read by the game coin tray reader 362a contains identification information that is not present in the latest identification information stored in the game table storage device 364, then for such game coin 72, the game table comparison device 363, like the aforementioned cashier comparison device 333, checks whether the identification information is stored in the database 326 and confirms whether the activation status corresponding to the identification information in the database is "valid".

[0107] (Reading the game coin tray) The following describes in detail the reading of game coins 72 stored in the game coin tray 36a. The game table comparison device 363 controls the game coin tray reader 362a to repeatedly read the game coins 72 in the game coin tray 36a at predetermined time intervals. The game table comparison device 363 typically instructs the game coin tray reader 362a to read the game coin ID from the RFID tag 721 of the game coin 72 without reading the tag ID. The game table comparison device 363 compares the read game coin ID with the latest game coin ID registered in the game table storage device 364 to determine whether a new game coin ID 72 with a new game coin ID that was not read at the previous reading exists; that is, it determines whether a new game coin 72 has been added to the game coin tray 36a.

[0108] If the new game coin 72 is not brought into the game coin tray 36a, that is, if the read game coin ID matches the latest game coin ID stored in the game table storage device 364, or if a portion of the latest game coin ID stored in the game table storage device 364 is not read, but no new game coin ID is read, the game table matching device 363 causes the game table storage device 364 to store the read game coin ID as the latest information. During the next read, it also controls the game coin tray reader 362a to read the game coin ID but not the tag ID.

[0109] On the other hand, new game coins 72 are added to the game coin tray 36a. As a result, when the game coin tray reader 362a reads a game coin ID that is not stored as the latest past game coin ID in the game table storage device 364, the game table comparison device 363 specifies the newly read game coin ID in the next read, and controls the game coin tray reader 362a to read the tag ID of the game coin 72 with that game coin ID based on the specified game coin ID. Furthermore, the game table comparison device 363 compares the tag ID read from the RFID tag 721 of the game coin 72 with the tag ID recorded in the database 326.

[0110] Figure 7This is a flowchart illustrating the RFID tag reading operation in the game table system according to an embodiment of the present invention. Antenna 361a and game coin tray reader 362a read game coin IDs from the RFID tags 721 of all game coins 72 within the game coin tray 36a (step S61). Game table comparison device 363 compares these read game coin ID combinations with the game coin ID combinations stored in the game table storage device 364 as the latest past game coin IDs, determining whether any new game coin IDs not stored in the game table storage device 364 exist among the read game coin IDs (step S62).

[0111] Upon receiving a new game coin ID ("Yes" in step S62), antenna 361a and game coin tray reader 362a designate the new game coin ID and, based on this new game coin ID, read the tag ID from the RFID tag 721 of the game coin 72 with the new game coin ID. The combination of the game coin ID and the tag ID is then sent to the processing room system 320 and compared with the information stored in the database 326 (step S63). Furthermore, the game table storage device 364 stores all combinations of the read game coin IDs as a new combination of past game coin IDs (step S64).

[0112] It should be noted that if the game table comparison device 363 does not read a new game coin ID ("No" in step S62), that is, if no new game coin 72 has been added to the game coin tray 36a since the last read, it determines whether there is a game coin ID that was read in the previous read but not read in this read by comparing the combination of game coin IDs read with the combination of the latest game coin IDs stored in the past by the game table storage device 364 (step S65).

[0113] If there are unread game coin IDs, that is, when game coin 72 is removed from game coin tray 36a ("Yes" in step S65), the game table storage device 364 stores the combination of all read game coin IDs as the combination of the latest past game coin IDs (step S64). On the other hand, if there are no unread game coin IDs ("No" in step S65), that is, if there is no addition, removal or change of game coin 72 in game coin tray 36a, the game table storage device 364 is not updated.

[0114] In this embodiment, the game coin tray 36a of the game table 36 typically reads the game coin IDs stored in the EPC area 212 at predetermined time intervals, monitors their changes, and when a game coin ID changes, particularly when a new game coin ID is read, the game coin 72 with the new game coin ID is compared with the database 326, and the activation status of the database 326 is confirmed. This reduces the processing burden and shortens the processing time required for one cycle (improving processing speed).

[0115] It should be noted that regardless of whether a newly read game coin ID exists, the game table comparison device 363 can perform a comparison with the database 326 and confirm the activation status of the database 326 at a specified time and / or under specified conditions. For example, the game table comparison device 363 may, upon receiving a notification indicating that the initial game card has been drawn from the electronic card shoe 36c, cause the game coin tray reader 362a to read the game coin ID, tag ID, and activation status from the game coins 72 in the game coin tray 36a, and perform a comparison with the database 326 and confirm the activation status. Furthermore, if there is a button operation for ending or starting the game in the electronic card shoe 36c, the game table comparison device 363 can control the game coin tray reader 362a to read the game coin ID and tag ID.

[0116] Figure 8 This is a flowchart illustrating a variation of the RFID tag reading operation in the game table system according to an embodiment of the present invention. In this example, antenna 361a and game coin tray reader 362a read game coin IDs from the RFID tags 721 of all game coins 72 in the game coin tray 36a (step S81). The game table comparison device 363 compares these combinations of read game coin IDs with the combinations of game coin IDs stored in the game table storage device 364 as the latest past game coin IDs, and determines whether there are any new game coin IDs among the read game coin IDs that are not stored in the game table storage device 364 (step S82).

[0117] Upon receiving a new game coin ID ("Yes" in step S82), antenna 361a and game coin tray reader 362a read the game coin ID and tag ID from RFID tag 721 for all game coins 72, send the combination of game coin ID and tag ID to the processing room system 320, and compare it with the information stored in database 326 (step S83). Furthermore, the game table storage device 364 stores the combination of all read game coin IDs as a new combination of past game coin IDs (step S84).

[0118] It should be noted that when the game table comparison device 363 does not read a new game coin ID ("No" in step S82), that is, when no new game coin 72 has been added to the game coin tray 36a since the last read, it compares the combination of game coin IDs read with the combination of the latest game coin IDs stored in the past by the game table storage device 364 to determine whether there is a game coin ID that was read in the previous read but not in the current read (step S85).

[0119] If an unread game coin ID exists, i.e., when a game coin 72 is removed from the game coin tray 36a ("Yes" in step S85), the game table storage device 364 stores the combination of all read game coin IDs as the combination of the latest past game coin IDs (step S84). On the other hand, if no unread game coin ID exists ("No" in step S85), i.e., if no game coin 72 is added, removed, or changed in the game coin tray 36a, the game table storage device 364 is not updated. It should be noted that, in the case of an unread game coin ID, in order to confirm, the game table matching device 363 controls the game coin tray reader 362a to read the unread game coin ID again. In this case, a game coin ID can be specified and the tag ID can be read.

[0120] Figure 9 This is a flowchart illustrating another variation of the RFID tag reading operation in the game table system according to an embodiment of the present invention. In this example, antenna 361a and game coin tray reader 362a read game coin IDs from the RFID tags 721 of all game coins 72 in the game coin tray 36a (step S91). The game table comparison device 363 compares these read game coin ID combinations with the game coin ID combinations stored in the game table storage device 364 as the latest past game coin IDs, and determines whether there are any new game coin IDs among the read game coin IDs that are not stored in the game table storage device 364 (step S92).

[0121] Upon reading a new game coin ID ("Yes" in step S92), the game table comparison device 363, based on the number of game coins 72 currently stored in the game coin tray 36a and the number of newly read game coin IDs, decides whether to read the game coin IDs and tag IDs of all game coins simultaneously (full reading) or to specify the newly read game coin ID and read the tag ID based on that game coin ID (specified reading) (step S93). In this variant, when the ratio of the number of newly read game coin IDs to the number of game coins 72 stored in the game coin tray 36a is greater than a predetermined threshold, the game table comparison device 363 decides to perform a full reading ("All" in step S93), thus controlling the game coin tray reader 362a. For all game coins 72, the antenna 361a and the game coin tray reader 362a read the game coin ID and tag ID from the RFID tag 721, send the combination of the game coin ID and tag ID to the processing room system 320, and compare it with the information stored in the database 326 (step S94).

[0122] On the other hand, when the ratio of the number of newly read game coin IDs to the number of game coins 72 stored in the game coin tray 36a is less than a predetermined threshold, the game table matching device 363 decides to perform a designated read ("designated" in step S93) and controls the game coin tray reader 362a in this way. The antenna 361a and the game coin tray reader 362a designate a new game coin ID and read the tag ID from the RFID tag 721 based on the game coin ID, send the combination of the game coin ID and the tag ID to the processing room system 320, and compare it with the information stored in the database 326 (step S95).

[0123] After the game table comparison device 363 reads the tag ID using either step S94 or step S95, the game table storage device 364 stores the combination of all read game coin IDs as the latest past game coin ID (step S96).

[0124] It should be noted that in this modified example, if the game table comparison device 363 does not read a new game coin ID ("No" in step S92), that is, if no new game coin 72 has been added to the game coin tray 36a since the last read, in the comparison between the combination of read game coin IDs and the combination of the latest game coin IDs stored in the game table storage device 364, regardless of whether there are game coin IDs that were read in the last read but not read in this read, the game table storage device 364 is updated by storing all read game coin IDs (step S96).

[0125] In the case of a specified read, game coin IDs must be searched one by one. Searching for game coins 72 with a single specified game coin ID takes time, and the process takes a considerable amount of time until the necessary tag ID is retrieved. On the other hand, in a full read, retrieving both the game coin ID and tag ID from all game coins 72 takes a considerable amount of time. Therefore, when the number of newly retrieved game coin IDs is relatively small, a specified read can be completed quickly. However, when the number of newly retrieved game coin IDs is large, a full read without searching for game coins 72 can be completed quickly. Therefore, in this modified example, as described above, the game table comparison device 363 determines whether to perform a full read or a specified read based on the total number of game coins 72 and the number of newly retrieved game coin IDs (the number of game coins 72 newly added to the game coin tray 36a). For example, a full read can be performed at a specified time, such as when the game coin tray 36a is powered on or when the game table 36 is started, to retrieve and compare both the game coin ID and tag ID.

[0126] (Reading the placement area) When player 74 places a game coin 72 in a designated area on the game table, antennas 361b1-361b6 are positioned below the placement area on the game table surface. A game coin reader 362b reads identification information from the RFID tag 721 of each placed game coin 72 in each placement area 36b1-36b6. The identification information read by the game coin reader 362b is compared with the information by the game table matching device 363 and stored in the game table storage device 364. When multiple game coins 72 are placed in placement areas 36b1-36b6, the game table storage device 364 stores multiple identification information corresponding to the multiple game coins 72.

[0127] Antennas 361b1~361b6 and the coin reader 362b not only read the coins 72 placed by the player 74 in the placement areas 36b1~36b6, but also read the RFID tags 721 of the coins 72 dispensed by the dealer 75 from the coin tray 36a. The game table storage device 374 also reads the RFID tags 721 of the coins 72 dispensed in this way.

[0128] The game table comparison device 363, for the identification information read from the RFID tag 721 by the game coin reader 362b, also performs activation status confirmation and comparison of the identification information with the game coins 72 stored in the game coin tray 36a. Specifically, for the identification information read by the game coin reader 362b, the game table comparison device 363 does not frequently compare it with the database 326. Instead, when new identification information not present in the latest past identification information stored in the game table storage device 364 as information read by the game coin reader 362b is read by the antenna 361b and the game coin reader 362b, the central comparison device 323 compares it with the identification information stored in the database 326 and confirms the activation status stored in the database 326.

[0129] The following describes in detail the reading of game coins 72 placed in placement areas 36b1 to 36b6. As described above, the electronic card shoe 36c outputs a signal to the game table comparison device 363 indicating that placement is complete. If the game table comparison device 363 receives this signal, it first controls the game coin reader / writer 362b to read the game coin IDs and tag IDs of all game coins 72 placed in placement areas 36b1 to 36b6. Furthermore, the game table comparison device 363 sends the read game coin IDs and tag IDs to the central comparison device 323, which compares the game coin IDs and tag IDs with the database 326. Additionally, the game table storage device 364 stores the game coin IDs read at this time.

[0130] Subsequently, the game table comparison device 363 controls the game coin reader 362b to repeatedly read the placement areas 362b1 to 36b6 at predetermined time intervals. During this time, the game table comparison device 363 instructs the game coin reader 362b to read the game coin ID but not the tag ID of the game coin 72. The game table comparison device 363 then determines whether the read game coin ID matches the game coin ID stored in the game table storage device 364 as the game coin ID at the end of placement.

[0131] Adding 72 coins to placement areas 36b1-36b6 after placement is complete and the initial game cards have been drawn is a violation of the rules (adding to placement or raising). Furthermore, removing 72 coins from placement areas 36b1-36b6 after placement is complete and the initial game cards have been drawn is also a violation of the rules (reducing bets). After the initial game cards have been drawn, a reduction in the 72 coins read from placement areas 36b1-36b6 is permitted when the dealer reclaims lost coins, and an increase in the 72 coins is permitted when the dealer reimburses won coins.

[0132] Therefore, if the game coin ID stored in the game table storage device 364 and read when the initial game card is drawn is not read in the placement areas 36b1-36b6, the game table comparison device 363 controls the game coin tray reader 362a to read the RFID tag 721 of the game coin 72 in the game coin tray 36a, monitoring whether the game coin ID that was not read in the placement areas 36b1-36b6 has been read by the game coin tray 36a. If, within a specified time, the game coin ID that was not read in the placement areas 36b1-36b6 is not read by the game coin tray 36a, the game table comparison device 363 outputs an error signal. In this case, it is suspected that there is improper behavior such as reducing the bet, or that the dealer has stolen the game coin 72 when collecting the lost game coins.

[0133] Furthermore, if a game coin ID (excluding the one read when the initial game card is drawn) is read in placement areas 36b1-36b6, the game table comparison device 363 determines whether the newly read game coin ID was stored in the game table storage device 364 as the game coin ID of the previous game coin tray 36a. If the newly read game coin ID was not stored in the game table storage device 364 as the game coin ID of the previous game coin tray 36a, the game table comparison device 363 outputs an error signal. In this case, improper placement or betting is suspected.

[0134] In this embodiment, at the end of placement, the game coin reader 362b reads the game coin ID and tag ID from the game coins 72 placed in placement areas 36b1 to 36b6, compares them, and then reads the game coin ID but not the tag ID, while monitoring its changes. Therefore, since the reading for monitoring changes is completed within a short comparison time, the reading interval can be shortened.

[0135] Furthermore, in this embodiment, whether to read only the game currency ID or both the game currency ID and the tag ID can be changed according to the game progress, thus ensuring both security and shortening the reading interval.

[0136] The electronic card shoe 36c can determine the time when placement ends, and the time for collection or payment. For example, the time when placement ends can be detected by drawing the first card from the electronic card shoe 36c, and the time for collection or payment can be detected by pressing the win / loss determination button equipped on the electronic card shoe 36c or by determining the win / loss based on the hand of the drawn card. Alternatively, based on the hand of the drawn card, if it is determined to be a P or B, it can be detected that payment or collection of the PAIR is possible.

[0137] (Registration invalidated) As described above, the registration device 325 registers the game coin 72 in the database 326 by storing the identification information of the new game coin 72 obtained from the factory in the database 326. On the other hand, for malfunctioning game coins 72 and old game coins 72, the registration device 325 can temporarily invalidate the activated state.

[0138] At each game item processing location, game coins 72 for which no information is read from the RFID tag 721 (i.e., game coins 72 with damaged RFID tags 721) are immediately excluded from usable game coins 72. Furthermore, game coins 72 for which the matching of identification information read from the RFID tag 721 fails are also immediately excluded from usable game coins 72. Further, game coins 72 with an invalid activation status are also excluded. The registration device 325 performs invalidation or activation procedures on these problematic game coins 72. Further, for game coins 72 that are not problematic but have been in use for a specified period (e.g., 1 year) since their initial activation time and date, invalidation procedures are performed to discard these game coins 72.

[0139] In the invalidation process, the registration device 325 updates the activation status of the game coin 72 recorded in the database 326 to "invalid," recording the update time and date. Alternatively, the registration device 325 can remove the information of the invalidated game coin 72 from the database 326. In the event of a malfunction in the RFID tag 721 of the game coin 72, the identification information that should be invalidated cannot be read from such a game coin 72. Therefore, the registration device 325 invalidates such a game coin 72 as described below.

[0140] Figure 10 This is a perspective view of a game coin in a decal-peeled state according to an embodiment of the present invention. The game coin 72 carries information for identifying the game coin 72 by a method other than an RFID tag 721. The game coin 72 has a circular recess in the center, and a decal 723 is attached to the bottom surface 722 of the recess. The decal 723 displays a number indicating the value of the game coin 72. If the decal 723 peels off, its bottom surface (decal attachment surface) 722 displays a game coin identification ID, serving as inherent identification information for the game coin 72. The game coin identification ID can be laser-engraved on the bottom surface 722 of the recess of the game coin 72, or it can be printed on the decal attachment surface 722 using a certain ink.

[0141] For game coins 72 whose identification information cannot be read from RFID tag 721, registration device 325 uses the game coin mark ID used to determine the game coin 72 to determine the identification information that should be invalidated and invalidates the registration. For game coins 72 whose identification information cannot be read due to RFID tag 721 malfunction, when invalidating them, the operator removes sticker 723, visually confirms the game coin mark ID marked on sticker affix 722, and inputs it into registration device 325 via input device 324. Registration device 325 refers to database 326 to determine the identification information corresponding to the input game coin mark ID (refer to...). Figure 5 Therefore, even if the game coin 72 with the RFID tag 721 is faulty, the game coin 72 can be identified in the database 326 and invalidated.

[0142] As described above, the game coins 72 given to player 74 circulate among multiple players 74 or game tables 36 due to being placed by player 74 or spent by dealer 75, and finally return to bank room 34 via game table 35. At this time, as described above, the game coins 72 excluded from the various game item processing positions are invalidated by registration device 325.

[0143] Furthermore, for game coins 72 that are problematic, not excluded, and returned to the bank 34, the bank system 34 performs a check on the identification information and confirms the activation status, further determining whether the prescribed period has elapsed since the initial activation. At this point, if game coins 72 are detected as having failed identification information checks, not being in a "valid" activation status, or having elapsed the prescribed period since initial activation, the invalidation procedure is performed on these game coins 72.

[0144] It should be noted that, at each game item processing location, after comparing the read identification information with the database 326, if the result is that game coins 72 not registered in the database 326 or game coins 72 whose activation status is not "valid", the registration device 325 can immediately invalidate the game coin 72 without waiting for it to be returned to the background 301. Furthermore, if the activation status of such a game coin 72 is "valid", the reader / writer at each game item processing location can rewrite its activation status to "invalid".

[0145] (Tracking game currency) As described above, the information for each game coin 72 in database 326 includes location history information 266. Each time the central comparison device 323 receives a comparison of identification information from each game item processing location, it updates the location history information 266 corresponding to that identification information. Specifically, when the central comparison device 323 receives a comparison of identification information from each game item processing location, it records the information determining the game item processing location as location information in the location history information 266 corresponding to that identification information, and records the time and date at that time as the reading time and date. In database 326, a predetermined number of information entries can be recorded as location history information; after recording this predetermined number of location history entries, the old information is overwritten.

[0146] As described above, the location information is used to determine the processing location of game supplies. For example, if there are multiple windows in the cashier's room 33, the window ID that identifies that window can be recorded as the location information. Since there are multiple game tables 35 and game desks 36, the game table ID and game desk ID used to identify which game table 35 and which game desk are recorded as the location information.

[0147] Furthermore, when game coin 72 is given to player 74, player ID of player 74 is recorded as location information. For example, if antenna 361b is set up for each player position on game table 36, player ID of each player position can be determined by the membership card held by player 74 or by facial recognition of the image of the player playing the game on game table 36.

[0148] Furthermore, by detecting which player's location the game currency 72 paid to was, it is possible to determine which player ID the game currency 72 was paid to. In addition, when player 74 purchases game currency 72 in the cashier's room 33, the player ID of player 74 is determined and recorded as part of the location information.

[0149] In this way, by recording the historical information of its location and the time and date of its reading in the database 326, it is possible to know how the game coin 72 was moved simply by referring to the database 326.

[0150] (A variation of the game table comparison device) As described above, the game table comparison device 363 instructs the game coin tray reader 362a to read the game coin ID from the RFID tag 721 of the game coin 72 without reading the tag ID. The read game coin ID is compared with the latest game coin ID registered in the past in the game table storage device 364 to determine whether there is a game coin 72 with a new game coin ID that was not read in the previous reading, that is, to determine whether a new game coin 72 has been brought into the game coin tray 36a.

[0151] Furthermore, when a new game coin 72 is added to the game coin tray 36a, and the game coin tray reader 362a reads a game coin ID that is not stored as the latest game coin ID in the game table storage device 364, the game table comparison device 363 controls the game coin tray reader 362a to specify the newly read game coin ID in the next read, and read the tag ID of the game coin 72 with that game coin ID based on the specified game coin ID. The game table comparison device 363 then compares the tag ID read from the RFID tag 721 of the game coin 72 with the tag IDs recorded in the database 326.

[0152] In this case, when the game coin tray reader 362a reads a tag ID corresponding to a game coin 72 with that game coin ID, the reading process may be unstable, and it may fail to read the tag ID corresponding to the specified game coin ID. In this situation, the game table matching device 363 temporarily determines that the game coin is compatible (temporarily OK) and stores this information along with the game coin ID. The next time the game table matching device 363 reads the tag ID again, using the game coin tray reader 362a with the game coin ID that was temporarily OK.

[0153] It should be noted that if the tag ID corresponding to the specified game coin ID is not read, the game table comparison device 363 first compares the game coin ID with the game coin ID recorded in the database 326. If a comparison is possible, it can be determined that it is temporarily OK.

[0154] When the game coin tray reader 362a can obtain the tag ID corresponding to the specified game coin ID, the game table comparison device 363 compares the read tag ID with the tag ID recorded in the database 326.

[0155] In this way, for newly added game currency IDs, if the corresponding tag ID cannot be obtained, it is temporarily considered "OK" and recorded as game currency that can be correctly read. This allows for a comparison of the game currency 72 that should be in the game currency tray 36a at that moment with the actual game currency 72 in the game currency tray 36a, and a determination of whether the liquidation process, such as the recovery of lost game currency, has been performed correctly. If game currency 72 for which the corresponding tag ID cannot be obtained is recorded as a read error or NG, then when determining whether the above-mentioned liquidation has been performed correctly, it will be judged as not having been performed correctly. Therefore, as described above, even if the tag ID cannot be read, it is recorded as "OK" temporarily, and the amount of game currency 72 is obtained based on the game currency ID, thereby enabling a determination of the correctness of the liquidation.

[0156] (A variation of the antenna on the game coin tray) exist Figure 5 In the example, the antenna 361a located on the coin tray 36a can be configured as a single antenna covering the entire coin tray 36a, or alternatively, multiple antennas can be used to distribute the coverage across different areas of the coin tray 36a. For example, eight antennas can be used to distribute the coverage across multiple areas and read the entire area of ​​the coin tray 36a. In this case, one coin tray reader 362a can be configured corresponding to one antenna, or one coin tray reader 362a can be configured corresponding to multiple antennas.

[0157] Furthermore, when the game coin ID of a newly added game coin 72 is read through a certain antenna, the game table matching device 363 controls the game coin tray reader 362a to specify the game coin ID and read the tag ID through that antenna and other antennas adjacent to it. In this way, if a reading is performed through the antenna that reads the game coin ID and other antennas adjacent to it, but no tag ID is read, it can be assumed that the antenna that read the game coin ID has read the game coin ID of the game coin 72 located in a more distant area.

[0158] Therefore, if the corresponding tag ID cannot be read even after reading the tag ID specified by the game coin ID a specified number of times using the antenna that reads the game coin ID and other antennas adjacent to the antenna, the game table matching device 363 controls the game coin tray reader 362a to read the tag ID specified by the game coin ID using all antennas.

[0159] It should be noted that even when multiple antennas are used to share the reading of a portion of the coin tray 36a, as long as each antenna can correctly read the coin ID of the coin 72 in its assigned area, it will not read the coin ID of the coin 72 in a distant area as described above, and therefore the aforementioned control is not required. This method of sharing the reading of the coin tray 36 with multiple antennas also applies to situations where the coin tray 36 is a double-layered coin tray, with each layer read separately by its own antenna. Furthermore, it is also applicable to separate reading of each placement area.

[0160] (Modified example) In the above embodiments Figure 3 and Figure 5 In the example, although the location history information is stored in database 326, the location history information can also be recorded in the RFID tag 721 of the game coin 72.

[0161] In existing gaming tokens, RFID reading can capture information written to the storage area and determine the token's authenticity. However, it cannot record and verify information acquired during actual use in the casino, particularly information related to the token's owner. Therefore, even genuine tokens with unusual usage histories, such as being used by owners different from the original owner or being exchanged between tokens, cannot be identified through RFID reading, making it impossible to prevent the use of such tokens with questionable usage histories in casinos.

[0162] Therefore, the purpose of this invention is to provide a system in which, in order to monitor and manage the owner information of each game coin in real time and improve security, the system can monitor and record which player the game coin has been transferred to when the dealer pays game coins to the player and the owner of the game coin changes from the casino to the player.

[0163] (first example) use Figure 11 This section will provide an overview of the first example of the desktop game management system. Figure 11 This diagram illustrates the overall structure of the system. A game table 1004 for a card game has placement areas for PLAYER 1441, BANKER 1442, TIE 1443, P 1444, and B 1445 at each player position 1131-1135. Furthermore, a coin storage area 1025 is provided for each player position, and an RFID coin reader 1002 is provided for reading coins 1001 placed in this coin storage area.

[0164] Furthermore, each game coin configuration area 1025 has a payment area 1026, which is used by the dealer to place the game coin 1001 taken from the game coin tray 1009 when the winning player pays the game coin 1001 from the game coin tray 1009 of the game table 1004.

[0165] 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.

[0166] Players starting the game place game coins 1001 in the designated placement area within the game coin configuration zone. Game coin reading device 1002 reads the RFID tag of the placed game coin 1001, thereby enabling control device 1003 to access information about the owner of the game coin 1001, which is associated with the ID information of the RFID tag, in the database.

[0167] 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 detects the RFID of the game coin 1001 in the game coin tray 1009, and the control device 1003 records in the database that the casino owns the game coin 1001 collected from the casino side.

[0168] Based on the game's outcome, the dealer, in accordance with the game rules, pays the winning player an amount of game coins, 1001, from the game coin tray, corresponding to the amount of game coins placed there.

[0169] When making a payment, the game currency can be placed in the payment area 1026 mentioned above, or it can be placed in the game currency configuration area outside the payment area.

[0170] Among them, utilizing Figure 12 This section explains the method for recording the owner information of the game currency used for payment. Figure 12 The document illustrates a method for recording information related to the owner of game coin 1001 when the winning player pays game coins.

[0171] When multiple players place game coins at the same player's position, creating more than two stacks, the game coin reading device 1002 reads all game coins 1001 placed in the game coin placement area 1025. Therefore, during the game, it doesn't know which game coin 1001 belongs to which player, but rather obtains the ID 1010 of the placed game coin. After the game's outcome is determined, when paying the winning player, the dealer pays each player (per stack) from the game coin tray 1009. The game coin 1001 taken from the game coin tray 1009 is 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.

[0172] The paid game coin 1001, along with the initially placed game coin 1001, is received by the winning player. At this time, the placed and paid game coins move outside the game coin configuration area 1025, and therefore, the IDs of the placed and paid game coins disappear from the reading results of the game coin reading device 1002. Thus, the control device 1003, by associating with information related to the owner of the placed game coin, determines which player the paid game coin was given to.

[0173] The control device 1003 stores information about the owners of the game coins it possesses in a database, associating the game coin's ID with that information.

[0174] As mentioned above, it is possible to track the owner of game currency 1001, and in cases of improper delivery of game currency 1001, it is possible to discover that the owner information stored in the database is different from the actual owner.

[0175] It should be noted that the actual owner can be identified using facial recognition technology or ID such as a membership card.

[0176] Furthermore, while the above description mentions managing the IDs of each game coin in a database, it could also be configured to store the owner information within the game coin 1001 itself.

[0177] In addition, the aforementioned payment area 1026 can exist at each player's location, or it can be formed independently of each player's location, or it can be read independently by the game coin reading device 1002.

[0178] Furthermore, it can be configured to select whether to use the payment area 1026 or not, depending on the reading performance of the game coin reading device 1002.

[0179] Furthermore, this desktop game management system can also be configured to be combined with 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 shoe that determines the outcome of the game, etc., so as to mutually utilize information.

[0180] (Second example) First, the game currency used in the management system of the game currency in the second variant example will be explained. Figure 13 A game coin 1 used in the same system is shown. In the same figure, the game coin 1 is embedded with an RFID tag 2 capable of storing various information. The RFID tag 2 has a non-rewritable data area 21 and a rewritable data area 22.

[0181] The non-modifiable data area 21 stores information that remains unchanged or unaltered during the use of game coin 1, or information that cannot be changed, as fixed information 3. Specifically, as fixed information 3, it stores information such as the production information, product information, casino information, amount information, and serial number of game coin 1. The production information includes the time and date of production of the game coin, the manufacturing machine, etc., and the product information includes, for example, information indicating that the game coin is used in the VIP area of ​​the casino, information indicating the type of game coin (e.g., information indicating that it is a transcoded coin), etc.

[0182] The unwritable data area 21 can be an area of ​​the RFID tag that is not rewritable in terms of specifications or functions, or it can be an area that is locked as unwritable after the necessary information is written in the writable area.

[0183] The rewritable data area 22 stores information that changes continuously during the use of game currency 1, referred to as change information 4. For example, as change information 4, such as... Figure 13 As shown, it stores location-related information 220, including information 221 related to time and date, information 222 related to location and event, or information 223 related to owner.

[0184] Fixed information 3 and variable information 4 can be encrypted to prevent unauthorized reading or writing of the information. Furthermore, fixed information 3 and variable information 4 can be stored as metadata.

[0185] Figure 14 This illustrates an example of a method for recording data related to the change information 4 of game coin 1. For example... Figure 14 As shown, the configuration is as follows: information 220 related to the location, including time and date, time information 221, location, event information 222, and owner information 223, is treated as a block, and this block of information is linked together to obtain the historical record of the information 220 related to the location of the game coin 1.

[0186] exist Figure 14 The following example illustrates the movement information 4 stored in Game Coin 1, allowing you to track its activity as shown below. At 16:02 on January 28, 2019, Mr. A purchased Game Coin 1 with cash at counter 5. At 16:15 on the same day, Mr. A placed Game Coin 1 at game table No. 325. At 16:43 on the same day, Mr. B received Game Coin 1 at game table No. 325 as payment for a winning placement. At 17:01 on the same day, Mr. B left the casino with Game Coin 1.

[0187] like Figure 14 As shown, the change information 4 can be configured to store only the latest information, or it can store all the relevant information that has been written. Furthermore, several pieces of relevant information can be selected for storage. When several pieces are selected for storage, multiple pieces of relevant information 220, including at least the latest relevant information 220, can be stored. Based on the above structure, the usage or movement history of a game coin 1 can be known based on the change information 4 of that game coin 1. That is, the tracking information of the game coin 1 can be written into the game coin 1 itself and is thus controlled.

[0188] Next, we will explain the management system for game currency 1 in this example. Figure 15 An overall overview of the same system is shown.

[0189] In game coin 1, firstly, at factory 6, the change information 4 containing information about manufacturing completion or factory shipment is written as information 220 related to the location into the rewritable data area 22 of RFID tag 2 by writing device 14.

[0190] In the casino's back office 7, the process of receiving game tokens 1 shipped from factory 6 is implemented. In back office 7, reading device 13 reads the change information 4 stored in the rewritable data area 22 of game token 1. Based on the reading result, management control device 15 determines whether the relevant information 220, which indicates information to be written and was written in factory 6, has been written as the latest change information 4. If there is no write record in factory 6, an error signal is generated as the game token is suspected of being fraudulent. Therefore, the casino can refuse to accept the game token and request the factory to investigate. If there is no problem with the write record, the relevant information 220 indicating the back office is written into the rewritable data area 22 of RFID tag 2 via writing device 14. During writing, information indicating the factory's location can be added and recorded along with information indicating the back office's location, or information indicating the factory's location can be deleted and recorded along with information indicating the back office's location. Furthermore, the reading or writing of game tokens in back office 7 can be performed simultaneously with the normal verification or activation of game tokens.

[0191] The game token 1, received and inspected in the background 7, is transported 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 token 1. Based on the reading result, the management control device 15 determines whether the relevant information 220, which should be written in the background 7, has been written as the latest change information 4. Furthermore, it can also check whether information representing factory 6 has been written into the history of change information 4. Similar to the checks performed in the background 7, the management control device 15 determines whether there are any anomalies in the history of the relevant information. If the reading result is correct, the writing device 14 writes the relevant information 22 representing warehouse 8 or counter 9 into the rewritable data area 22.

[0192] 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. This can be configured to identify and record the player using facial recognition technology or an ID card such as a casino membership card or identity verification card.

[0193] Players use game token 1, which is used for exchanging game coins, to place game token 1 in placement area 11 on the game table. Reading device 13 reads information 220 related to the game token 1 from its RFID tag 2, including time and date, time information 221, location and event information 222, or owner information 223. Management and control device 15 then determines if there are any anomalies. For example, if a certain period has passed since the last written usage information on the game table or the exchange information at the counter, and the owner information 223 stored in game token 1 differs from the owner information 223 determined through facial recognition or ID card, an anomaly can be identified.

[0194] If there are no issues with reading, the writing device 14 adds associated information 220 to the writable data area 22 for the placed game coin 1. The associated information 220 includes time and date, time information 221, location, event information 222, and owner information 223. On the game table, for example, the writing device 14 writes change information 4 containing the player's location number and player information. The player's information can be identified via ID card or facial recognition. Typically, several game coins 1 are stacked in the placement area 11; therefore, they are written together in a stacked state.

[0195] When a player takes game token 1 out of the casino's game pool, an exit process is initiated at entrance / exit 10. During exit, the reading device 14 reads the relevant information 220, and the management control device 15 determines whether there are any anomalies in the change information 4. Furthermore, at entrance / exit 10, the writing device 14 writes change information 4, which includes information indicating the exit location, event information 222, and owner information 223.

[0196] When a player enters the casino's gaming pool, if they bring in game tokens 1 that they previously took out, the reading device 13 reads the relevant information, and the management control device determines whether there are any anomalies in the change information 4. For example, if the owner of game tokens 1 that has been taken out of the casino is different from the owner at the time of entry, it can be determined that there was an act of delivering game tokens outside the casino.

[0197] If the reading result from the reading device 13 indicates an anomaly, the aforementioned 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 exchanges game tokens at the counter 9 or leaves through the entrance / exit 10, they can refuse the exchange based on the alarm output by the management control device 15, or undergo individual checks upon leaving. Furthermore, if the determination result is abnormal, the management control device 15 can make the following judgments: issue a warning to the dealer of each game table to interrupt the game, or issue a warning to the game table manager, who then decides whether to interrupt or continue the game; or process the exchange for game token 1, etc. 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 all management control devices 18.

[0198] Similar to the management control device 15, when exchanging game coins at the counter, the reading device 13 can read the change information 4 and determine if there is an anomaly. Specifically, an anomaly can be determined if a certain period has passed since the last written information, the usage information on the game table, or the exchange information at the counter, or if an exchange is to be made between game coins by someone 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 the exchange of the game coin 1.

[0199] Furthermore, in the above description, the writing device 14 performs writing after the reading and management control device of the reading device 13 makes a determination, but it can also be configured to perform reading and writing simultaneously.

[0200] The following shows the details of an application example of this example.

[0201] In factory 6, RFID tags 2 are read and / or written when production is completed or when shipment is made. Production information and product information are written as fixed information 3, locked so that they cannot be rewritten as needed, and change information 4 is written.

[0202] In the background 6, when receiving game coin 1 shipped from the factory as usable game coin 1 for activation, the RFID tag 2 is read and / or written.

[0203] In warehouse 8, when game token 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 token 1 stored in warehouse 8, RFID tag 2 can be read and / or written at fixed intervals or at specified times.

[0204] At counter 9, RFID tags 2 are read and / or written when the device moves from or to warehouse 8, or when a customer purchases game tokens 1 with cash. In the case of a purchase at counter 9, change information 4 is written as owner information 223, indicating the location of the purchase, event information 222, and the player information. Owner information 223 can be obtained from the player's casino ID card, facial recognition system, credit card, etc.

[0205] At entrance / exit 10, RFID tags 2 are read and / or written when players enter or leave. When a player leaves, all game tokens 1 taken out of the casino are registered by writing information indicating the location and event 222 to indicate the location, the player's ownership information 223 to indicate the location, the player's ownership information 223 as change information 4. When a player enters, the game tokens 1 brought into the casino are also registered by writing information indicating the location and event 222 to indicate the location, the player's ownership information 223 ...

[0206] In placement area 11, RFID tags 2 are read and / or written to game coins 1 placed by players in placement area 11 for the purpose of participating in placement. In addition, RFID tags 2 are read and / or written to game coins 1 placed by the dealer in placement area 11 as compensation to players.

[0207] In the game coin tray 12, the RFID tag 2 is read and / or written to the game coins 1 that have been returned to the game coin tray and the game coins 1 that are stored.

[0208] The game table also has a payment area 2007 and a payment area 1026. The game coins 1 placed in the placement area 11 by the dealer as compensation to the players can be read and / or written to by RFID tags 2.

[0209] The management control device 15 has the function of determining whether the information 220 related to the location obtained from the reading results of the reading device 13 at each location is normal. As a determination of whether there is an anomaly, it can determine whether there is any event such as not using the information for a specified period of time since the last writing, or the failure to write the information related to the location that should have been written.

[0210] The event that has not been used for more than the specified period since the last write includes any of the following conditions: 1) The latest information related to the location is the information for counter 9, and the next information will be written after a specified period of time; 2) The latest information related to the location is the entry information at entrance / exit 10. The next information will be written after a specified period of time. 3) The latest information related to the location is the information indicating that the person left through entrance / exit 10. The next information will be written after a specified period of time.

[0211] An event in which the information that should have been written but was not written includes any of the following situations: 4) When entering the amusement park, the information related to the latest location of the rewritable data area 22 of the game coin 1 is not written, indicating that the player will leave through entrance / exit 10. 5) When used at counter 9, information representing backend 7 was not written; 6) When leaving the amusement park, information indicating counter 9 or backstage 7 was not written.

[0212] Based on the owner-related information 223 obtained from the reading device 13, the management control device 15 can determine any one of the following situations as an event for judging whether an anomaly is occurring: 1) People who are different from the final owner stored in the rewritable data area 22 can exchange game coins in the amusement park or leave the amusement park; 2) A person who is different from the owner at the time of departure stored in the rewritable data area 22 brings the game coin into the amusement park.

[0213] The management control device 15, based on information obtained from the reading device 13 indicating the location of the placement area 11, or the location of the game coin tray 12, or the payment area, determines, as an event of abnormality, any one of the following conditions 1) to 4): 1) A person different from the final owner stored in the rewritable data area 22 uses the game coin 1 on the game table; 2) Game Coin 1, which has no usage record at the game table, is exchanged between game coins at counter 9 by a different person than the one who purchased Game Coin 1 at counter 9; 3) Use game token 1 within the amusement park that does not indicate counter 9 or backstage 7; 4) The latest information related to the location is the information of the placement area 11 or the payment area. After a specified period, game coins can be exchanged at counter 9 or used at the game table.

[0214] Figure 18 The database is shown as another example of a variant. The management system also includes a database 17 that records the same fixed information 3 and variable information 4, in addition to game coin 1. 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 game coin 1 with the information in the database to determine anomalies.

[0215] In the RFID tag 2 in this example, the non-functionally writable data area 21 can be a TID. The area locked after necessary information is written to the non-rewritable data area 21, preventing further data writing, can be an EPC or a user area. The rewritable data area 22 can be an EPC or a user area.

[0216] The reading device 13 and the writing device 14 can change their form depending on the location. For example, in factory 6, for Figure 16 The device on the platform shown is box-shaped at the entrance / exit 10, and in the placement area 11 or the coin tray 12, the placement area 11 or the coin tray 12 itself can have the functions of a reading device 13 and a writing device 14. Furthermore, the coins 1 can be directly stacked, and reading and / or writing can be performed while they are stored in the coin box, etc. Moreover, the reading device 13 and the writing device 14 can be integrated into one unit.

[0217] In the above variation, the case where the game coin has a single RFID tag with both a non-writable and a writable data area was described. Conversely, another approach could be considered: embedding two RFID tags into the game coin. One tag is locked to store fixed information, preventing data from being written to it, while the other tag is configured to record changing information and is set to writable data.

[0218] However, in this case, when reading multiple game coins together, such as Figure 17A As shown, the information groups of fixed information 3 and variable information 4 are read respectively. Therefore, it is impossible to determine the combination of fixed information and variable information of a specific game currency, and it is impossible to determine the game currency with abnormal variable information.

[0219] In this case, if there is only one RFID tag, such as Figure 17B As shown, even when reading multiple game coins together, it is believed that implementing a single RFID tag is better because the reading device can grasp the correspondence between the fixed and variable information read.

[0220] Furthermore, generally speaking, the larger the diameter of the RFID tag, the higher the reading accuracy. Therefore, when RFID tags are inserted into game coins, the RFID tags are preferably sized with a diameter at least equal to the radius of the game coin. However, since two RFID tags are inserted into the game coin, the smaller the diameter of each RFID tag, the better. Additionally, inserting two RFID tags increases the number of RFID tags to be read, thus reducing the reading speed when reading multiple game coins.

[0221] Based on the above points, it is believed that implementing this through a single RFID tag will yield better results.

[0222] (Third case) The following is an overview of the management system for tabletop games in an amusement park with multiple game tables, as described in the third variation. Figure 19 As shown in the diagram illustrating the overall structure of the same system, the management system for tabletop games in an amusement park with multiple game tables 2004 includes: a game recording device 2011 that records the games played on the game tables 2004, including game coins 1, as images using 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 of each game on the game tables 2004.

[0223] The game result determination device 18 is, for example, a card dispensing device 2003, which is a so-called electronic card shoe already used by those skilled in the art. It can be configured such that the game rules are pre-programmed, the information of the dispensed cards C is read, and the winner of the game is determined. For example, in a certain card game, the winner of the BANKER, the winner of the PLAYER, and the TIE are basically determined by the face value of 2-3 cards, and the determination result (win / loss result) is displayed by the result display light 2013.

[0224] In the same attached diagram, game table 2004 is a card game table with 5 seats 13 ("Seat No. 1" 131, "Seat No. 2" 132, "Seat No. 3" 133, "Seat No. 5" 134, and "Seat No. 6" 135), allowing 5 players to participate. Each seat 13 has a placement area 44. Placement areas 44 for seat 13 include PLAYER 441, BANKER 442, TIE 443, P 444, and B 445. Each player places a game coin 1 in the position corresponding to the placed object, thus initiating the game. Figure 19 For example, two game coins 1 are placed on TIE443 at seat number 5, and two game coins 1 are placed on PLAYER441. Game table 2004 has a PLAYER card area 45 for placing drawn PLAYER cards and a BANKER card area 46 for placing drawn BANKER cards.

[0225] The control device 2014, through the camera 2002 and the image analysis device 2012, can determine the location (PLAYER, BANKER, TIE, or PAIR) of each player 2006 in the placement area 2008, the type (each color of the coin has a different monetary value), and the number of coins placed. For example, it can determine that two coins were placed in TIE 443 at seat number 5, and two coins were placed in PLAYER 441.

[0226] like Figure 19 As shown, the game coin reading device 25 is configured to treat the entire placement area as a reading area for each seat number, and read the RFID tags of the game coins 1 present within the reading area. The RFID tags attached to the 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 grasp the game coins 1 for each seat number, and can grasp the total amount or number of coins. That is, for example, if 4 game coins are placed at seat number 5, it can grasp the type, amount, and ID of each game coin.

[0227] like Figure 20 As shown, the control device 2014 obtains the type and number of game coins 1 placed in each seating area based on the image analysis results from the image analysis device 2012, and determines the total amount or total number of game coins 1 for each seating number. This is then compared with the total amount or total number of game coins 1 for each seating number obtained from the RFID information of the game coins 1 read by the game coin reading device 25 to determine if they match. Furthermore, the control device can output the seating numbers determined to be inconsistent, thus identifying problematic seating numbers.

[0228] If the total amount or number of game coins 1 for each seat number obtained from image analysis based on the image analysis device is less than 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, it is possible that the RFID tag attached to the game coin 1 is damaged, is unreadable, or that the game coin 1 does not have an RFID tag attached. Figure 20 Regarding game coin 1 placed at seat number 1, the total number of reads obtained from image analysis by image analysis device 2012 is 4, while the total number of reads obtained from RFID reading by game coin reading device 25 is 3. Therefore, for game coin 1 placed at seat number 1, it can be considered that RFID cannot be read for 1 out of 4 coins.

[0229] Compared to the total amount or number of game coins 1 per seat number obtained from the image analysis results of the image analysis device, if the total amount or number of game coins 1 per seat number obtained from the reading results of the game coin reading device 25 is larger, it can be considered that there may be situations where game coins 1 are not read by the image analysis device 2012 due to reasons such as entering the blind spot of the camera. Figure 20 Regarding the game coin 1 placed at seat number 3, the total number of reads obtained from image analysis by image analysis device 2012 is 1, while the total number of reads obtained from RFID reading by game coin reading device 25 is 2. Therefore, it is possible that there are 2 game coins 1 placed at seat number 3, but the image analysis device only identifies 1 coin.

[0230] The RFID ID information attached to game token 1 is registered in the casino's database, recording information on its production and shipment at the factory, or its receipt, verification, and activation at the casino. Control device 2014 can compare the RFID information read by game token reader 25 with the information in the database to determine the authenticity of the game token registered for use in the casino.

[0231] According to this structure, the type and number of game coins 1 placed in each placement area are monitored by the camera, and the authenticity of the game coins 1 is determined based on the RFID information of the game coins 1 read by the game coin reading device 25, and the game coins 1 are determined to be illegitimate or defective for each seat number.

[0232] In addition, the system also includes a participant identification mechanism using facial recognition or player ID cards. The control device 2014 can associate the participant information identified through this mechanism with their seat number. The control device 2014 can store the placement amount, repayment or recovery amount, and win / loss information for each seat number for each participant. Furthermore, it can aggregate and store data from multiple games played by participants at multiple game tables.

[0233] The control device 2014 uses 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 is settled, it can compare and calculate whether the total amount of game coins 1 in the coin tray 17 has increased or decreased based on the game's outcome, including the recovery of lost game coins 1 by each player 2006 and the payout of 90,000 game coins to the winning player 2006W. The coin tray determining device uses a camera 2002 to photograph the game coins 1 stored in the coin tray 17. Based on the analysis of the image, it determines the total amount of game coins 1 in the coin tray 17. An RFID reader is installed in the coin tray 17 to detect the total amount of game coins 1 stored therein.

[0234] In this example, based on the game's outcome, the information of which type of game coin 1 was placed in which position (PLAYER, BANKER, TIE, PAIR) in the placement area 2008 and how many were placed, as well as the increase or decrease in the amount of game coin 1 in the game coin tray 17 after the loss of game coins and the repayment of the winning game coins 1, cheating or errors can be detected. Therefore, even without knowing the movement of the game coin 1 after the game ends, i.e., whether the placed game coin 1 moved to the player's side or to the dealer's side, cheating or errors can be detected.

[0235] In the case of a card game, for example, the card dispensing device 2003 reads the face value of the card C drawn in the game, thereby determining the winner according to the rules of the card game. Alternatively, the game table 2004 can be filmed by a camera 2002, the image analysis device 2012 can analyze the image, and the control device 2014 can compare 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 (PLAYER, BANKER, TIE, P, B) and what type of game coin 1 each player at seat number 7 placed in the placement area 2008 is obtained by filming the game coin 1 placed in the placement area 2008 with the camera 2002, and then analyzing the image for each player's position 7 with the image analysis device 2012.

[0236] Furthermore, by comparing the total amount of game coins 1 in the game coin tray 17 before the recovery of lost game coins 1 and the repayment of winning game coins 1, and the total amount of game coins 1 in the game coin tray 17 after the recovery of lost game coins 1 and the repayment of winning game coins 1, the increase or decrease in the amount of game coins 1 in the game coin tray 17 before and after the recovery of lost game coins 1 and the repayment of winning game coins 1 can be calculated.

[0237] For example, let's define the total amount of Game Coin 1 in Game Coin Tray 17 before the game starts as Bb, and the total amount of Game Coin 1 in Game Coin Tray 17 after the game ends, including the recovery of lost Game Coins and the repayment of won Game Coins, as Ba. Furthermore, in this game, the total amount of Game Coin 1 placed in the PLAYER area across all player positions 7 is bp, the total amount of Game Coin 1 placed in the BANKER area across all player positions 7 is bb, and the total amount of Game Coin 1 placed in the TIE area across all positions 7 is bt. For example, if the BANKER wins the game, Ba - Bb = bp - bb + bt should hold true. Alternatively, the total amount of Game Coin 1 in Game Coin Tray 17, Ba, after the game ends should be (Bb + bp - bb + bt). If this is not the case, it can be determined that there was cheating or error in the recovery or repayment of Game Coins.

[0238] Figure 24A A diagram illustrating the details of the game coin tray in this example. Figure 24B The diagram illustrates another example of a game coin tray. The game coin tray 17 includes a return game coin tray 171 for temporarily storing and collecting game coins 1L placed by the losing player 2006L, and a repayment game coin tray 172 for storing game coins 1W used for repayment. The image analysis device 2012 and control device 2014 determine the location, type, and number of game coins 1L placed by the losing player 2006L, and calculate the increase in the amount of game coins 1L in the game (the expected amount of game coins 1 in the return game coin tray 171). Furthermore, the image analysis device 2012 and control device 2014 determine the actual total amount of game coins 1 in the returned game coin tray 171, compare the expected total amount with the actual total amount, and determine if there is a discrepancy.

[0239] The control device 2014 can also compare the total amount due in the game coin tray obtained based on the amount due in the game coin 1 and the actual total amount in the game coin tray after the repayment is completed, and determine whether there is a difference between the total amount due and the actual total amount. The amount due in the game coin is calculated based on the position, type and number of game coins placed by each game participant in the game table and the game result.

[0240] Furthermore, by using the game coin 1 in the game coin tray 172 to repay the game coin 1W of the winning player 2006W, it is possible to ensure that the image analysis device 2012 and the control device 2014 have sufficient time to grasp the actual total amount of game coins 1 in the recycled game coin tray 171.

[0241] As described above, in the third example, the control device 2014 calculates the inflow and outflow of game coins in each game based on the amount of game coins placed on the game table 2004 and the game's outcome, and detects any increase in the balance of game coins in the game coin tray 17 after the game. If a discrepancy is detected in this detection, the control device 2014 issues an alarm or adds a record indicating the situation to the video recording taken by the camera 2002. The casino operator can determine the cause of the discrepancy by reviewing the video.

[0242] In the third example, the tabletop game management system adds or subtracts the total amount of game coins 1 in the game coin tray 17 before each game's settlement, based on the position, type, and number of game coins 1 placed by all players 2006 in the game and the game's win / loss result obtained by the win / loss result determination device. It then compares the expected total amount of game coins 1 in the game coin tray 17 after the game's settlement with the actual total amount of game coins 1 in the game coin tray 17 at the end of the game, obtained by the image analysis device 2012, to determine whether there is a difference between the expected total amount and the actual total amount.

[0243] The control device 2014 uses the image analysis device 2012 to grasp 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. It 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 of game coins 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.

[0244] The control device 2014 compares the total amount of game coins 1 in the game coin tray 17 before each game settlement with the increased amount of game coin tray 17 in the game, calculated by adding the amount of game coin tray 17 based on the position, type, and number of game coins 1 placed by the losing player, to the actual total amount of game coins 1 in the game coin tray 17. If there is no difference between the expected total amount and the actual total amount, and the control device 2014 compares the expected total amount in the game coin tray 17 after the game ends with the actual total amount of game coins 1 in the game coin tray 17 obtained by the image analysis device 2012 at the end of the game, and determines that there is a difference between the expected total amount and the actual total amount, a payment error is determined, and a payment error signal is issued to notify of the payment error.

[0245] The game coin tray 17 is equipped with a game coin collection tray 171 for collecting and temporarily storing the game coins 1 placed by the losing player. The image analysis device 2012 compares the expected total amount of game coins 1 in the game collection tray 171, which is calculated by adding the amount of game coins 1 in the game based on the position, type and number of game coins 1L placed by the losing player, with the actual total amount of game coins 1 in the game collection tray 171, and determines whether there is a difference between the expected total amount and the actual total amount.

[0246] 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, the game recording device 2011 adds an index or time to the acquired image, or determines and recreates the recycling scene or payment scene of game coins 1, so that the game recording device 2011 can analyze the game record that caused the above discrepancy.

[0247] In this way, the control device 2014 obtains the total amount of game coins in the game coin tray 17 after the game ends by means of the image analysis device 2012. The determination after the settlement in this case can be made under any of the following 1) to 4).

[0248] 1) When the winning game coin 1 is repaid at the end; 2) When card C used in the game is recycled and discarded to the discard area 41 or discard slit 42 of the game table; 3) When the designated button attached to the win / loss result determination device is pressed; 4) Restore the marker 43 indicating win or loss.

[0249] Furthermore, the control device 2014 employs an AI-efficient or deep learning structure that: it grasps the position (placed in PLAYER, BANKER, PAIR positions) and amount (type and number of coins) of game coins placed on each player's position 7 at the game table 2004; it compares the win / loss history of each player 2006 obtained from the win / loss results of each game with the statistical data of a large number of past games (big data), and extracts it as an anomaly (set by the casino). Typically, the control device 2014, possessing an AI-efficient or deep learning structure, can compare the following with past game statistics (big data, etc.): if a certain amount of winnings (1 million points) or more occurs, or if a player's position 7 at the game table 2004 experiences a situation where the amount of game coins placed when losing is small and the amount of game coins placed when winning is large for several consecutive games, it can extract this anomaly by comparing it with past game statistics (big data, etc.).

[0250] Furthermore, the control device 2014 of this tabletop game management system is configured (integrated with the image analysis device 2012) to extract abnormal situations or identify individual players 2006 at position 7 who have won a specified amount or more. Such players 2006 can be pre-determined in the image analysis device 2012 by extracting feature points from facial images and attaching an identification number (ID, etc.). Moreover, the control device 2014 has a warning function that notifies the other game table of the presence of the identified player when the identified player 2006 leaves to sit at another game table. Specifically, it notifies the game table manager or the person in charge of each game table (which could be the dealer) to prevent further abnormalities.

[0251] The control device 2014 can determine the game coin 1 that has been recycled for each seat number based on the RFID ID information of the recycled 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.

[0252] exist Figure 21 In, such as Figure 22 and Figure 23 As shown in the detailed table, game token 1 was placed. The image analysis device 2012 can determine the location (PLAYER, BANKER, etc.) where game token 1 was placed, the number of tokens (and their value). On the other hand, the game token reader 25 can determine the RFID ID of the game token 1 attached to each seat number. Furthermore, the game token tray determining device can determine the ID of the game token 1 within the game token tray 9, thus determining the ID added before and after recycling, thereby identifying the recycled game token 1. Figures 23-25 If the game result is that BANKER wins, the analysis results from the image analysis device 2012 show that the two game coins placed at B should be recycled. It can be seen that among the IDs of the game coins to be recycled determined by the game coin tray determination device, the two coins ID6 and ID18 placed at seat number 5, which were read by the game coin reading device 25, are recycled.

[0253] The control device 2014 also knows the total amount or total number of game coins 1 to be recovered for each seat number, determined by the game results obtained from the game result determination device and the image analysis results based on the image analysis device, based on the determination results of the position, amount, and number of game coins 1. Therefore, the control device 2014 can compare the total amount or total number of game coins 1 recovered for each seat number determined based on RFID with the total amount or total number of game coins 1 to be recovered based on the image analysis results, and determine whether they are consistent.

[0254] 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 "2 coins placed in TIE, 2 coins placed in BANKER", the game result is "BANKER wins", and the reading result of the game coin tray determination device 18 is "A, B", then it can be known that the A and B game coins placed in TIE have been correctly recovered.

[0255] The control device 2014 can also determine whether the RFID ID information of the game coin 1 recovered by the game coin tray determination device is consistent with the RFID ID information of the game coin 1 placed on the table read 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 1 placed on the game table, or the game coin 1 improperly recovered from other places.

[0256] The control device 2014 can also determine the type of game coins such as transcoded and promotional codes based on the RFID information read by the game coin reader 25, and can store the amount placed, the amount of recycling or repayment according to the determined type of game coin.

[0257] Transcodes are special game tokens that can be purchased by specific members and cannot be exchanged for cash. The management of each member's purchase amount for transcodes ensures they are held for consumption. By storing the amount of transcodes placed or retrieved based on RFID information read by the game token reader 25, the management can track the amount of transcodes a specific member should possess.

[0258] The game coin reader 25 also has a confirmation area function, capable of reading game coins 1 placed for repayment. For example... Figure 25 As shown, when repaying the BANKER for seat number 2, game coin 1 for repayment is placed in the game coin reading device 25, and the coin is read. Figure 25 The winning game coin 1 is placed next to the BANKER at seat number 2. The control device 2014 compares the repayment amount determined based on the game results from the game result determination device and the image analysis results from the image analysis device, using the determination results of the position, amount, and number of game coins 1, with the amount of game coins 1 placed at each seat number based on the reading results of the game coin reading device 25, determines whether the repayment amounts are consistent or inconsistent, and outputs the result. Figure 26In 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, and the dealer can reposition the game coins 1 used for repayment based on the output signal. After repositioning the game coins 1, a second judgment can be made, and the judgment result is output. The area where the game coins 1 used for repayment are placed can be any position within the game coin reading device 25. Furthermore, as... Figure 25 As shown, a payment confirmation area 26 can be configured separately from the placement area, on the dealer's side of the placement area. Figure 25 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 placed next to the winning game coin 1 placed in the BANKER.

[0259] In addition, the image analysis device 2012 also performs image analysis on the confirmed area, and the control device 2014 can compare the reading results with those of the game coin reading device 25 to determine whether the total number of coins is consistent.

[0260] Based on the determination made by the control device 2014, the system can output a signal. The signal can be displayed on the display unit of the coin tray 9 or the display unit of the card dispensing device 13, and can be output to the game table manager or the casino's back office.

[0261] Game coin reader 25 can be like Figure 27 As shown, the entire placement area can be treated as a single reading area for each seat number, or as follows: Figure 28 As shown, according to each seat number, the PLAYER and BANKER placement areas are used as one retrieval area, and the TIE, P, and B placement areas are used as one read area. Furthermore, as... Figure 29 , 32 As shown, the side placement areas of the TIE placement area, P placement area, and B placement area can also be used as a reading area respectively.

[0262] The following is an explanation of the game coin 1 used in this example. Figure 30 This is the appearance image of game currency 1 used in this system. Figure 31This is a front sectional view. It is formed by stacking multiple plastic layers of different colors, with a colored layer 101 at least in the middle, and white layers 102 or light-colored layers (although not shown, any layer lighter than the colored layer 101) stacked on both sides of the colored layer 101. By forming a multi-layer structure with a colored layer 101 and white layers 102 or light-colored layers (although not shown, any layer lighter than the colored layer 101) stacked on both sides of the colored layer 101, it achieves the desired effect. Figure 31 The striped pattern formed on the side has a stacked direction, which can change the color of the coloring layer 101 (red, green, yellow or blue, etc.) to determine the type of game coin 1 (10 points, 20 points, 100 points, 1000 points, etc.).

[0263] Shading layer 101 as Figure 31 The diagram shows that multiple layers can be colored (in...) Figure 31 The middle three layers are formed. Due to the multiple layers of coloring ( Figure 31 The middle layer consists of 3 layers that are heat-pressed together, therefore, as Figure 31 As shown, the three-layer structure is not in a visually confirmable state. Figure 31 The diagram shows three layers. Further, a portion of the central layer within the three layers of the colored layer 101 has a cutout B, in which an RFID tag is embedded.

[0264] Furthermore, the game coin 1 is not limited to a structure of plastic layers, but may also have a structure that does not have the same appearance as the coloring layer 101.

[0265] The following describes in detail the method by which the image analysis device 2012 analyzes the game coin 1. 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. It should be noted that the specific color 121 is at least partially attached to a predetermined location on the game coin 1 or at least partially attached in a predetermined shape. For example, it may be attached as a coloring layer 101, attached circumferentially to the side of the game coin 1, or attached as a predetermined mark on the surface of the game coin 1. Furthermore, the reference color R may be, for example, the color of a specific area of ​​the game table 2004, or the color of a location on the game coin 1 that is different from the specific color 121.

[0266] The image analysis device 2012 includes an artificial intelligence device 12a that determines specific colors, for example, through deep learning technology, and determines the number and type of game coins 1 placed on the game table 2004. The recognition device 12 can also determine the position of the game coins 1 on the game table 2004.

[0267] The image analysis device 2012 acquires multiple images of the game coin 1 and the reference color R under different illumination levels. The acquired images, along with the correct colors of the specific color 121 of the game coin 1 and the reference color R in each image, are used as teacher data for instruction, thereby creating a learning mode 13a (recognition program). It should be noted that for images of the game coin 1 and the reference color R under the same illumination conditions, by illuminating the specific color 121 and the reference color R with the same illumination, the relative relationship between the specific color 121 and the reference color R can be obtained. For example, this relative relationship can be used for the recognition of the specific color 121.

[0268] Furthermore, the game coin recognition device 12 can extract the center line C of the game coin 1 by taking and recording images with the camera 200212, and then using the results of image analysis to measure features on the image such as shape, brightness, saturation, and hue.

[0269] The artificial intelligence device 12a also includes the following structure: it performs image analysis on a defined range of surrounding images (e.g., a range of 8 pixels perpendicular to the center line, centered on the center line) around the extracted center line C, thereby identifying at least two colors in the surrounding images: the specific color 121 and the reference color R, which is different from the specific color 121. It should be noted that when performing image analysis on the defined range of surrounding images 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 facilitate the identification of the specific color 121.

[0270] In summary, the artificial intelligence device 12a of the recognition device 12 is an artificial intelligence device that is capable of extracting the center line C from the image of the game coin 1, performing image analysis on the surrounding image within a specified range centered on the center line C, thereby identifying the structure of at least two colors in the surrounding image, namely a specific color 121 and a reference color R different from the specific color 121, and using multiple surrounding images of the game coin 1 and the reference color R obtained by illuminating them with different illuminances as teacher data for teaching.

[0271] In other examples, the control device 2014 also has the function of determining at least one of the following conditions: 1) In each game, from the time the cards are drawn or from the start of the dealer's game until the game's outcome is displayed by the card-distributing device, is there any movement of game coins? 2) During the period after each game ends, when the dealer collects the game coins placed by the losers among the game participants, is there any movement of game coins by anyone other than the dealer? 3) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, are additional game coins added? 4) After each game, did the dealer pay out the winning coins placed by the players? 5) After each game ends, did the winners among the game participants take away the placed game coins and the game coins that were paid out?

[0272] Furthermore, the control device 2014 may be configured to use the analysis results of the image analysis device to detect the hand movements of the dealer and the game participants, the movement of game coins, or the hand movements and the movement of game coins, thereby determining at least one of 1) to 5).

[0273] The control device 2014, according to the rules of a certain card game, has the functions shown in 1) to 5) below. As a characteristic function of this invention, it determines whether cheating that violates the rules has occurred. That is, 1) In each game, from the time the card drawing starts signal received by the free card dispensing device 2003 or the dealer 2005 presses the start button for 4 seconds to start the game until the card dispensing device 2003 displays the game's winning or losing result, the image analysis device 2012 uses information obtained by the camera 2002 to monitor whether there is any movement of game coin 1. 2) After each game ends, during the period when the dealer 2005 collects the game coins 1 placed by the losers among the game participants 2006, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the loser 6 has improperly taken away the game coins 1. 3) After each game ends, during the period when the dealer 2005 collects the game coins 1 placed by the losers among the game participants, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether anyone other than the dealer 2005 (winner or loser) adds the winning game coins 10,000 or replaces new game coins 1 on the winning side where no coins were placed. 4) After each game, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the dealer 2005 has correctly placed the game coin 1W to the winner among the game participants 2006; 5) After each game ends (the dealer 2005 operates the card distribution device 2003 to display the win / loss results on the display light 13), the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the winner 6W among the game participants 2006 has taken away the placed game coin 1 and the game coin 1W that was paid out.

[0274] It should be noted that in the above example, 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 use Scale-Invariant Feature Transform (SIFT) algorithms, Convolutional Neural Networks (CNNs), deep learning, mechanical learning, or similar devices to perform image analysis or the various controls described above. These technologies are techniques for image recognition of captured images and for identifying 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 involves stacking multiple layers in the intermediate layers between the input and output layers of the neural network to identify objects with high accuracy. Among these deep learning techniques, convolutional neural networks, in particular, have attracted attention due to their higher performance compared to object recognition based on conventional image feature quantities.

[0275] In a convolutional neural network, labels are learned on the image to identify the main objects within that image. When multiple main objects exist within the image, they are designated as rectangular regions, and labels are added to the images corresponding to these regions for learning. Furthermore, the convolutional neural network can determine the main objects within the image and their locations.

[0276] To further explain the convolutional neural network, in the object recognition step, edge extraction and other processing are performed on the image of the object to be recognized, thereby extracting a supplementary region based on local features. This supplementary region is then input into the convolutional neural network, and classification is performed based on the extracted feature vectors. The supplementary region with the highest certainty factor is selected as the recognition result. The certainty factor refers to the measure of how much higher the similarity of the subject in an image region and its label is compared to other levels of similarity.

[0277] The above examples illustrate various embodiments. However, it is natural that those skilled in the art can make modifications within the scope of this invention, and can appropriately change the apparatus of this embodiment according to the needs of the game to which it is applied.

[0278] (Fu Ji) To solve the aforementioned problems, the game currency management system of the present invention is configured as follows: The game tokens are attached to a single RFID tag with both non-rewritable and rewritable data areas. The non-tamperable data area of ​​the RFID tag stores at least one of the following as fixed information: production information, product information, casino information, amount information, and serial number of the game coin. The rewritable data area stores information related to the location of the game currency, serving as change information. It is possible to extract the variable information stored in the rewritable data area of ​​the same RFID tag from the fixed information stored in the non-rewritable data area. The system also has: A writing device that writes information about the location of the game coin to the area of ​​the rewritable data; A reading device that simultaneously reads the fixed information stored in the immutable data areas of multiple game coins, and based on the read fixed information, can read information related to the location stored in the immutable data areas in pairs with each piece of fixed information; and A management and control device that reviews information related to the location obtained from the reading device. The rewritable data area stores multiple pieces of information related to a location in such a manner that it includes at least the most recent information related to the location from all information related to the location written by the writing device. The management and control device is configured to determine whether there are any anomalies in the historical records of information related to the location obtained from the reading device. If an anomaly is found, an error signal is generated to determine the fixed information of the game currency that is determined to be abnormal.

[0279] Furthermore, the rewritable data area is configured to store information related to the location and information about the time when the writing device writes the game coin. The management and control device is configured to determine, based on the information related to the location obtained from the reading device, whether there is any of the following situations: either the information that has not been used since the last specified writing period has not been written, or the information related to the location that should have been written has not been written, as a determination of whether it is the abnormality.

[0280] Furthermore, in the management and control device, the information related to the location includes at least one of the following: information indicating the counter, information indicating entry or exit, or information indicating the back office. The situation where the data has not been used since the last write can be any of the following: 1) The latest information related to the location is the counter information, and the next information will be written after a specified period of time; 2) The latest information related to the location indicates entry information; the next information will be written after a specified period of time. 3) The latest information related to the location indicates the exit information, and the next information will be written after a specified time.

[0281] The situation where the relevant information that should have been written has not been written can be any of the following: 4) Upon entering the amusement park, the latest information related to the location of the rewritable data area of ​​the game coin was not written with information indicating exit; 5) When used at the counter, no information indicating the backend was written; 6) When leaving the amusement park, no information indicating the counter or backstage was written.

[0282] Furthermore, the information related to the location may include information related to the owner of the game currency.

[0283] Furthermore, as a means of determining whether an anomaly exists based on information related to the owner obtained from the reading device, the management device may be configured to have the function of determining either 1) or 2) below. 1) A person who is different from the final owner stored in the rewritable data area exchanges game coins or leaves the amusement park; 2) A person who is different from the owner at the time of departure stored in the rewritable data area brings the game coin into the amusement park.

[0284] Furthermore, information related to the owner of the game currency can be determined through facial recognition or ID card reading.

[0285] In addition, the information related to the location may also include information indicating the location of the coin tray of the specific game table, or information indicating the location of the placement area, or information indicating the payment area.

[0286] Furthermore, as a means to determine whether an abnormal situation exists based on information indicating the location of the game coin tray on the game table, the location of the placement area, or the payment area obtained from the reading device, the control device may have the function of determining any one of the following conditions 1) to 4). 1) A person different from the final owner stored in the rewritable data area uses the game coin at the game table; 2) Game tokens without a usage record at the game table were exchanged between game tokens at the counter by a different person than the one who purchased the game tokens at the counter; 3) Using game tokens in amusement parks that do not indicate a counter or back office; 4) The latest information related to the location indicates the placement area or payment area. After a specified period, game coins can be exchanged at the counter or used at the game table.

[0287] Furthermore, the information contained in the RFID tag can be encrypted.

[0288] Furthermore, the unwritable data region can be a structure that cannot be functionally written to or a structure that is locked to prevent data from being written to.

[0289] Furthermore, the reading device is configured to read together the fixed information stored in the non-writable data area and the related information stored in the writable data area. The management and control device can be configured to extract and grasp the information related to the location stored in the rewritable data area of ​​the same RFID tag from the fixed information of the multiple game coins read by the reading device.

[0290] To address the aforementioned problems, the game coin of the present invention possesses a single RFID tag having a non-rewritable data area and a rewritable data area. The non-rewritable data area stores at least one of the following as fixed information: production information, product information, casino information, amount information, and serial number of the game coin. The rewritable data area is configured to store information related to the location of the game coin, written by the writing device, as change information. The configuration is such that the variable information stored in the same RFID tag in the same RFID tag can be extracted from the fixed information stored in the non-rewritable data area.

[0291] Furthermore, the game coin can be configured such that a reading device can read the fixed information stored in the non-rewritable data area of ​​multiple game coins, and based on the read fixed information, it can read the information related to the location stored in the rewritable data area.

[0292] To address the aforementioned problems, the desktop game management system of the present invention has the following features: Game tokens, each with an attached RFID tag that can be individually identified; A game table for playing games using the game coins; A game recording device that records images of game coins placed by each player at the game table via a camera. An image analysis device that performs image analysis on the recorded image of the game coin; A game coin reading device that reads the RFID tags attached to the game coins placed by each game participant; and The control device monitors the image analysis results from the image analysis device and the reading results from the game coin reading device. The game table has multiple placement areas, each including at least a placement area for the player and a placement area for the banker for each seat number. The game coin reading device is configured to read the game coins by treating the entire placement area as a single reading area for each seat number, or to divide the entire placement area into multiple reading areas (less than the number of placement areas) and read the game coins for each reading area. Based on the image analysis results of the image analysis device, the control device independently determines the type and number of game coins placed in each placement area, which includes at least the PLAYER placement area and the BANKER placement area. It then determines whether the total amount or number of game coins for each seat number or each reading area, based on the image analysis results of the image analysis device, and the total amount or number of game coins for each seat number or each reading area, based on the reading results of the game coin reading device, are consistent, and outputs the determination result.

[0293] Furthermore, the control device may be configured to output seat numbers where the determination results are inconsistent.

[0294] Furthermore, the control device may also be configured to generate a signal indicating that the RFID tag attached to the game coin may be damaged or that the game coin is not attached to the RFID tag when the total amount or number of game coins for each seat number is less than the total amount or number of game coins for each seat number based on the reading result of the game coin reading device, compared to the total amount or number of game coins for each seat number based on the image analysis result of the image analysis device.

[0295] Furthermore, the control device may also be configured to generate a signal indicating the possibility that the image analysis device has made a reading error on the game coins when the total number of game coins for each seat number is greater than the total number of game coins for each seat number based on the image analysis results of the image analysis device.

[0296] In addition, it has a database that stores the IDs of the RFID tags attached to the game tokens. The control device can be configured to 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.

[0297] In addition, it also has: A coin tray that holds coins for the dealer to use on the game table; A game coin tray detection device, capable of determining the type and quantity of game coins stored in the game coin tray; and The game result determination device determines the game results of each game on the game table. The control device has the following calculation function: using the game results obtained from the game result determination device and the image analysis results from the image analysis device, as well as the determination results of the position, amount, and number of game coins, it calculates the income and expenditure on the casino side of the game table according to each round of collection and repayment in each game. It can also have: The coin recycling judgment function, at the end of the recycling of game coins placed by each game participant, compares the amount of game coins to be recycled (calculated based on the position, type, and number of game coins placed by each player on the game table and the game results) with the actual amount recycled from the coin tray to determine if there is a discrepancy between the amount to be recycled and the actual amount recycled, thereby determining whether there was cheating or error in the recycling of game coins; and The repayment determination function performs the repayment of corresponding game coins. At the end of the repayment, it compares the total amount of game coins due to be repaid with the actual total amount in the game coin tray. If there is a difference between the total amount due and the actual total amount, it is determined that there is cheating or error in the repayment. The amount of game coins due to be repaid is calculated based on the position, type, and number of game coins placed by each player on the game table and the game result.

[0298] Furthermore, the control device determines the number of game coins collected for each seat number 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. The ID, amount, or number of game coins determined by the game coin's location, amount, and number of game coins used are compared with the ID, amount, or number of game coins to be recovered for each seat number, and it is determined whether they are consistent for each seat number. The determination results of the game coin's location, amount, and number of game coins are based on the game results obtained from the game result determination device and the image analysis results from the image analysis device.

[0299] Furthermore, the control device can be configured such that, in each game, the game coin reading device reads the RFID ID information of the game coin, determines the category of the game coin's usage purpose or purpose, and can store the amount placed, the amount recovered, or the amount repaid for each game coin of the category for each seat number.

[0300] Furthermore, the control device can be configured to, in multiple games, store, redeem, or repay the accumulated amount of each type of game coin for each seat number.

[0301] Furthermore, the type of game currency can be at least transcoding or promotional codes.

[0302] Furthermore, the control device may be configured to determine the owner based on the ID information of the transcode, and for each owner, store the cumulative amount of the transcode placed, or the cumulative amount of recovery or repayment.

[0303] Furthermore, the game coin reading device reads the game coins placed in the device for repayment for each seat number. The control device may be configured to compare the repayment amount determined by measuring the position, amount, and number of game coins with the amount of game coins placed at each of the seat numbers based on the reading results of the game coin reading device, and determine and output whether the repayment amount is consistent or inconsistent, wherein the measurement results of the position, amount, and number of game coins are obtained based on the game results obtained from the game result determination device and the image analysis results of the image analysis device.

[0304] Furthermore, the control device may be configured to display an inconsistency when the determination result of the repayment amount is inconsistent; furthermore, if the amount of game coins read by the game coin reading device and placed in the game coin reading device of each seat number changes, a determination may be made here, and the consistent or inconsistent result may be output again.

[0305] Furthermore, the control device may be configured to compare the amount of game coins placed at each of the seat numbers for repayment with the increase or decrease in the amount of game coins in the tray before and after repayment, and determine whether there is a difference.

[0306] In addition, the game coin reading device may have a payment confirmation area, which is configured on the dealer side of the placement area for placing the game coins for repayment.

[0307] In addition, it also has the capability to identify game participants using facial recognition systems or player ID cards. The control device may be configured to associate the seat number with the information of the game participant determined by the game participant determination agency.

[0308] In addition, a display device may be provided, which displays the output of the control device.

[0309] In addition, the game table also has a side-mounted placement area. The side placement area is arranged adjacent to the placement area for each seat number. The game coin reading device is capable of reading at least one of the side-placed placement areas in a comprehensive manner. The control device may be configured to, based on the image analysis results of the image analysis device, determine the type and number of game coins placed in at least one of the side placement areas, and output a signal indicating whether the total amount or total number of game coins in the at least one side placement area 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 based on the reading results of the game coin reading device.

[0310] Furthermore, another aspect of the present invention is a management system for desktop games, wherein, The management system for this desktop game includes: Game tokens, each with an attached RFID tag that can be individually identified; A game table used for playing games using the game coins; A game recording device that records images of game coins placed by each player during a game on the game table via a camera. An image analysis device that performs image analysis on the recorded image of the game coin; A game coin reading device that reads the RFID tags attached to the game coins placed by each game participant; and The control device monitors the image analysis results from the image analysis device and the reading results from the game coin reading device. The game table has a placement area, which includes a placement area for the player, a placement area for the banker, and a placement area for side play. The side placement area is arranged adjacent to the placement area for each seat number. The game coin reading device is capable of reading at least one of the side-placed placement areas in a comprehensive manner. The control device is configured to, based on the image analysis results of the image analysis device, independently 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 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 based on the reading results of the game coin reading device, and output a signal of the determination result.

[0311] Furthermore, the control device may be configured to output the side placement as inconsistent with the determination result.

[0312] Furthermore, the control device may also be configured to generate a signal indicating that the RFID tag attached to the game coin may be damaged or that the game coin is not attached to the RFID tag when the total number of game coins placed on each side is less than the total number of game coins placed on each side based on the image analysis results of the image analysis device.

[0313] Furthermore, the control device may also be configured to generate a signal indicating the possibility of a reading error of the game coins by the image analysis device when the total number or total number of game coins placed on each side is greater than the total number or total number of game coins placed on each side based on the reading results of the game coin reading device.

[0314] In addition, it has a database that stores the IDs of the RFID tags attached to the game tokens. The control device can be configured to 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.

[0315] Furthermore, the control device can be configured to determine the game coins placed on each side based on the RFID ID information of the game coins recovered as 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 can compare the ID, amount, or number of game coins to be recovered on each side, determined by the measurement results of the position, amount, and number of game coins, with the ID, amount, or number of game coins recovered on each side, and determine whether the amount of recovered game coins is consistent or inconsistent for each side. The measurement results of the position, amount, and number of game coins are based on the game results obtained from the game result determination device and the image analysis results from the image analysis device.

[0316] When a game coin or a stack of game coins that should be accepted for payment is present in a game coin reader 25, the placed game coin can be paired with the payment game coin and associated with the owner information even without detecting whether the game coin has moved outside the area of ​​the game coin reader 25. That is, when a game coin 1001 or a stack of several game coins 1001 is present in a game coin reader 25, the placed game coin and the payment game coin can be paired based on information that the payment game coin has disappeared from the game coin tray or information about the payment game coin read by the game coin reader 25 on the game table, and thus associated with the owner information. Of course, it can be configured such that, based on information that the game coin has moved outside the area of ​​the game coin reader 25, the placed game coin is identified, and using several pieces of information—including information about the game coin removed from the game coin tray, information about the game coin placed in the placement area, and information about the game coin moved outside the area of ​​the game coin reader 25—the payment game coin and the placed game coin are paired, thereby associating the owner information of the placed game coin with information related to the owner of the payment game coin. Alternatively, it can be configured such that the ID of the game coin is read via RFID, and the type and quantity of game coins, including stack identification, are performed using a camera.

[0317] In a coin reader 25, the presence of a single stack of coins or game coins that are to be paid includes situations where, at the time of placement, there is only one stack of coins or game coins in the area, or where, at the time of placement, there are several stacks, but during payment, the stack becomes the last one. It can be configured to pair only the last stack of placed game coins with the payment coin and associate it with the owner information. In this case, the remaining last stack is designated as the coin placed by a member, thereby enabling reliable tracking of the member's game coins. Preferably, one member places coins at each coin reader (e.g., each player position), while several non-members may place coins. With one member at each player position, since the game coins are associated with the owner, information about the member assigned to each player position can be obtained from the information on the placed game coins. Furthermore, in cases where there is a rule that members place game coins before non-members, within a player position, the first placed game coin can be associated with the member information assigned to that player position (e.g., sitting in player position 1), or it can be confirmed that the first placed game coin is associated with the member information assigned to that player position. Membership cards can be used when assigning members to player positions.

[0318] The coin reader 25 can be installed in each area of ​​the PLAYER, BANKER, TIE, PAIR, etc., or the entire game table can be divided into multiple sections based on player positions, such as player positions 1-3 and player positions 4-6, with each section serving as a single large reader 25. In either case, it can match placed coins with paid coins and update owner information based on information such as coins moving outside the area of ​​the coin reader 25 (coins not read by the coin reader 25), the ID of paid coins disappearing from the coin tray, and the ID information of paid coins placed in the placement area.
