Game token tray, table game management system, game token tray system, and game token management method
A game token tray system includes a game token tray having a dual tray structure in which a game token is stored. The game token tray system includes a double tray including a lower tray and an upper tray stacked on the lower tray to store a game token provided with an RF tag in which tag information is stored, a camera that acquires tray image data by imaging the game token stored in the upper tray, an RIFD reading device that reads the tag information from the RF tag of the game token stored in the lower tray, and a game recording device that records the tray image data and/or an image analysis result of the tray image data about the game token stored in the upper tray and records the tag information read by the RFID reading device about the game token stored in the upper tray.
1. A management system configured to manage game tokens, each game token of the game tokens including a radio-frequency (RF) tag storing tag information and a side code associated with the tag information marked on a side of the game token, the management system comprising:
an image capturing device configured to capture an image of a plurality of the game tokens stored in a chip tray;
an image analyzer configured to, based on the image and for each game token of the plurality of the game tokens, obtain a position of the game token and the side code;
a reader configured to read, for each game token of the plurality of the game tokens stored in the chip tray, the RF tag of the game token to obtain the tag information of the game token; and
a fraud detection device configured to:
determine that a first game token of the plurality of the game tokens for which the side code obtained by the image analyzer does not correspond to the tag information of the plurality of the game tokens obtained by the reader, is a fraudulent game token or a potentially fraudulent game token, and
identify the position of the fraudulent game token or the potentially fraudulent game token.
2. The management system according to claim 1 , further comprising:
a database configured to store, for each game token of the game tokens, the tag information in association with the side code of the game token,
wherein, to determine the fraudulent game token or potentially fraudulent game token, the fraud detection device is further configured to:
refer to the database and determine whether the tag information corresponds to the side code the first game token, and
identify the position of the fraudulent game token or potentially fraudulent game token.
3. A management system according to claim 2 , wherein the fraud detection device is further configured to record the position of the fraudulent game token or the potentially fraudulent game token and a time associated with detection of the fraudulent game token or the potentially fraudulent game token.
4. The management system according to claim 1 , further comprising:
a database configured to store, for each game token of the plurality of the game tokens, the side code of the game token,
wherein the fraud detection device is further configured to determine, for each game token of the plurality of the game tokens, whether or not the side code identified by the image analyzer is stored in the database.
5. The management system according to claim 4 , wherein the fraud detection device is further configured to determine that a second game token having a side code that is not stored in the database is the fraudulent game token or the potentially fraudulent game token.
6. The management system according to claim 1 , wherein the fraud detection device is further configured to detect, when two or more game tokens of the plurality of the game tokens with the same side codes are obtained, that the two or more game tokens of the plurality of the game tokens are the fraudulent game token or the potentially fraudulent game token.
7. The management system according to claim 5 , wherein the fraud detection device is further configured to identify the position of the fraudulent game token for which the side code identified by the image analyzer is not stored in the database.
8. The management system according to claim 1 , wherein:
the chip tray is located on a gaming table,
the image capturing device is further configured to capture a table surface of the gaming table to obtain table image data, and
the fraud detection device is further configured to identify where on the table surface the fraudulent game token or the potentially fraudulent game token was collected from based on the position of the fraudulent game token or the potentially fraudulent game token and the table image data.
9. The management system according to claim 1 , wherein the fraud detection device is further configured to identify, for each game token of the plurality of the game token, a position of the side code of the game token.
10. The management system according to claim 1 , wherein the fraud detection device is further configured to detect one or more game tokens of the plurality of the game tokens that has a damaged RF tag or does not have an RF tag.
11. The management system according to claim 1 , wherein the fraud detection device is further configured to determine from which player or from which player position the first game token collected in the chip tray came from.
