FIELD

The present disclosure relates to a management system for a game token coin that avoids the use of fraud game token coins in a gaming house, such as casinos and other game facilities where game token coins are used.

BACKGROUND AND SUMMARY

In many table games played in gaming houses, such as casinos, there are baccara and blackjack. In the casinos, game token coins are used for such games.

The use of fraud game token coins must not happen in casinos. In order to avoid the use of fake game token coins in the casino, there is a technique in the casino that determines whether a game token coin is a fake or not with an RFID tag attached to the game token coin and avoids the use of fakes. RFID-attached game token coins are publicly known, and an RFID-attached game token coin is disclosed in WO2008/120749 A. It is generally known that the RFID tag has a memory region in which the manufacture unique information of the RFID tag itself and a memory region in which a user can write necessary information. In the RFID-attached game token coin, information indicating the value of the game token coin, a serial number, and any other information are written.

Conventionally in the RFID-attached game token coin, the operation is performed in which after necessary information is written in a memory region, in which the user can write information, the memory region is locked, and unauthorized rewrite is avoided. In the game token coin based on such a previously existing technique, it is possible to determine whether the game token coin itself is fake or not by reading RFID to specify the information written in the memory region. However, RFID fails to store information obtained on casino sites during use. Therefore, reading RFID fails to determine the presence of game token coins having unusual history on the point of use situations, such as game token coins that are genuine but are not used for a longtime and game token coins that are used or exchanged by an owner who is different from its right owner, and the avoidance of the use of such game token coins having unusual use history in the casino fails. There is a concern that taking advantage of such game token coins having unknown history (the history of location relating information), game token coins in the casino may be used for crimes, including money-laundering, for example, and the solution to the concern is asked for.

Therefore, an object of the present disclosure is to provide a game token coin and a management system that enable additional write of information on an RFID tag, allow the RFID tag of the game token coin to retain the use history of the game token coin, and enable the finding of a fraud game token coin having unusual use history based on the written use history.

In order to solve the previously existing problem, in a management system for a game token coin according to the present disclosure, one RFID tag having a data non-rewritable region and a data rewritable region is imparted to a game token coin, the data non-rewritable region of the RFID tag is configured to store, as constant information, at least one of production information, product information, casino information, value information, and a serial number of the game token coin, and the data rewritable region is configured to store, as variable information, location relating information (or formation about the whereabouts) of the game token coin, in which from the constant information (or fixed information) stored in the data non-rewritable region of an RFID tag, the variable information stored in the data rewritable region of the same RFID tag is extractable. The system further includes a writer configured to additionally write the location relating information of the game token coin in the data rewritable region, a reader configured to collectively read the constant information stored in the data non-rewritable region of a plurality of the game token coins and to read the location relating information stored in the data rewritable region that is paired with each of the constant information based on the read constant information, and a management controller configured to examine the location relating information obtained from the reader. The data rewritable region stores information relating to a plurality of locations including at least latest location relating information of all sets of the location relating information written by the writer, and the management controller includes a function that determines whether a history of the location relating information obtained from the reader has no abnormality, in which the management controller is configured to generate an error signal when an abnormality is found, and the management controller is configured to identify the constant information of a game token coin that is determined that an abnormality is found.

The data rewritable region is configured to store the location relating information and information on time at which the writer makes a write on the game token coin, and the management controller is configured to determine, from the location relating information obtained from the reader, as determination whether the abnormality or not, whether there is any event that the game token coin is not used for a predetermined period or more from a previous write, or that the location relating information which has to be written is not written.

In the management controller, the location relating information may include at least one of information indicating a cage, information indicating entering or leaving, and information indicating a backyard, and the event that the game token coin is not used for a predetermined period or more from a previous write is any situation in which 1) latest location relating information is information indicating a cage, and a subsequent information write is made after an elapse of a predetermined time or more, 2) latest location relating information is information indicating entering, and a subsequent information write is made after an elapse of a predetermined time or more, and 3) latest location relating information is information indicating leaving, and a subsequent information write is made after an elapse of a predetermined time or more. The event that the location relating information that has to be written is not written is any situation in which 4) when a player enters gaming house, as latest location relating information of the data rewritable region of the game token coin, information indicating leaving is not written, 5) when a game token coin is used at a cage, information indicating a backyard is not written, and 6) when a player leaves gaming house, information indicating a cage or a backyard is not written.

The location relating information may include information relating to an owner who owns the game token coin.

The management controller may include a function that determines any situation 1) or 2) as the event that is determined whether an abnormality or not based on the owner relating information obtained from the reader in which 1) a person who is different from a final owner stored in the data rewritable region converts the game token coin into money or makes exchange of game token coins in a gaming house, or leaves gaming house, and 2) a person different from an owner in leaving stored in the data rewritable region brings in the game token coin in the gaming house.

The information relating to an owner who owns the game token coin may be identified by face recognition or reading an ID card.

The location relating information may further include information indicating a place of a chip tray of a specific game table, or information indicating a place of a bet area, or information indicating a payment area.

The management controller may include a function that determines any of situations 1) to 4) as the event that is determined whether an abnormality or not based on information indicating the place of the chip tray of the game table, or information indicating the place of the bet area or a payment area obtained from the reader in which 1) a person who is different from a final owner stored in the data rewritable region uses the game token coin at a game table, 2) a person who is different from a person who purchases a game token coin at a cage converts the game token coin into money at the cage, and the game token coin does not have use record at a game table, 3) a game token coin having no information indicating a cage or a backyard is used in a gaming house, and 4) latest location relating information is information indicating a bet area or a payment area, and a game token coin is converted into money at the cage or used at game table after a lapse of a predetermined period or more.

Information that the RFID tag has may be encrypted.

The data non-rewritable region may be configured to functionally write no data or is locked so as to allow no data write.

The reader may be configured to collectively read the constant information stored in the data non-rewritable region and location relating information stored in the data rewritable region of an RFID tag, and the management controller may be configured to extract the location relating information stored in the data rewritable region of the same RFID tag from a plurality of sets of the constant information of a plurality of the game token coins read by the reader and determine the location relating information.

In order to solve the previously existing problem, a game token coin according to the present disclosure includes one RFID tag having a data non-rewritable region and a data rewritable region.
