Abstract: A server device uses cameras to capture the images of cards dealt to players and a dealer. The server device automatically judges the game win/lose result of the players and the dealer and the dividends of the players through image recognition based on the card images from the cameras. The server device reads information from the wireless IC tags provided on game chips to judge the dividends of the players. The server device compares between the two dividends of a player to judge whether or not the dividends are inconsistent. If the dividends are inconsistent, the server device notifies the dealer and a casino hotel manager that the dividends are inconsistent.

Abstract: A gaming system is provided enabling real-time cash management to be performed, even while in the play of a game to be performed by employing game media rendering their items of recorded information readable. Having received a result of detection of game chips on a game betting board from a game betting device, a server device accumulates the result of the detection, and judges whether or not movement of game chips has occurred between a dealer and each player, in comparison with a past result. When movement of game chips has occurred between the dealer and such each player, data relevant to a game chip table, a player table, and a dealer table is updated so as to reflect a result of the movement.

Each wireless tag stores information to be read magnetically. The high magnetic permeability member is placed between the wireless tags, prevents a magnetic field from affecting the wireless tag on the black side at a time when the information stored in the wireless tag on the white side is magnetically read from the white side, and prevents a magnetic field from affecting the wireless tag on the white side at a time when the information stored in the wireless tag on the black side is magnetically read from the black side.

Abstract: When the same gaming chip is identified in betting regions, a betting apparatus identifies an intermediate position of the betting regions as a tentative position of the gaming chip. The betting apparatus determines whether or not gaming chips are placed on the same betting region based on a distance between tentative positions of the gaming chips. When a gaming chip is identified in one betting region, the betting apparatus determines that the gaming chip is placed on a center position of the betting region. When gaming chips are not placed on the same betting region, the betting apparatus determines that the gaming chips are placed on tentative positions of the gaming chips. When gaming chips are placed on the same betting region, the betting apparatus determines that the gaming chips are placed on an intermediation position on a line connecting tentative positions of the gaming chips.

Abstract: A betting apparatus for game includes a betting board, antennas and a control unit. The antennas are arranged to regions on the betting board and detect a gaming chip placed on the betting board. The control unit turns on or off an electric current to each of the antennas. When the control unit turns on an electric current to one antenna arranged to one region, the control unit shorts another antenna arranged to another region adjacent to the one region.

Abstract: Gaming chips 30 have an IC tag 34 which is embedded therein, and a special bar code 101 invisible to the naked eye, which is printed thereon. A server calculates the number of gaming chips 30 based on individual information of the IC tag 34 that was read out by a reader 38, based on individual information of the special bar codes 101 read out by a bar code scanner 102, based on weight data acquired at a weighing device 40 and based on image data processed in a camera 103. Further, the server checks a partial number or the total number of gaming chips 30 thus calculated, and outputs the check results from a display or speaker.

Abstract: A non-contact IC card can accept a frequency band different from the main receive frequency band of the non-contact IC card. The non-contact IC card has a main antenna supporting a first frequency band and an IC device connected to the main antenna for data transmission and reception. An attaching body, detachably attached to the non-contact IC card has a sub-antenna supporting a second frequency band different from the first frequency band.
