When an unfair gaming currency is delivered to a dealer from a player, the currency is detected as unfair. The inspection system for inspecting the gaming currency, in which an RF tag is built, comprises: a gaming currency tray for housing the gaming currencies of the dealer in a casino game; an RF reader for reading the RF tags of the plural gaming currencies housed in the gaming currency tray; plural photosensors for detecting at least the number of the plural gaming currencies housed in the gaming currency tray at a constant time interval or always in a method other than RFID; and an inspection/alarm part for generating alarms when the number of the gaming currencies whose RF tags are read by the RF reader is not equal to the number of the gaming currencies detected by the plural photosensors.

A gaming chip in which it is not easy to remove an RFID tag and difficult to damage the RFID tag through use is provided. A gaming chip that incorporates a sticker-type RFID tag including an enclosing member having a predetermined shape for enclosing the RFID tag; a body member that is injection-molded to encapsulate the enclosing member with the RFID tag; and a gaming chip for amusement. The enclosing member consists of a first part and a second part, and at least the first part or the second part has a flat surface to which a sticker-type RFID tag can adhere, and the first part and the second part are combined to form an enclosing member, in which the sticker-type RFID tag is covered by the first part and the second part.

A game token money includes a plurality of plastic layers laminated through thermocompression bonding including at least a colored layer in the middle to specify a value of the game token money and a pair of pale color layers laminated on both sides of the colored layer. An RFID is embedded in a layer other than the outermost layer of the plurality of plastic layers; and a classification part is filled in at least one of the pale color layers to indicate a classification of the game token money. The classification part is recognizable from a side face and a front face of the game token money. The RFID contains information regarding a value of the game token money and a classification of the game token money indicated by the classification part.

A management system includes a recording device recording an image of a gaming chip and an inspection device determining a type and authenticity of the gaming chip. The gaming chip has a multilayer structure in which both sides of a colored layer are sandwiched between light color layers, surface printing representing a type of the gaming chip is performed on outer sides of the light color layers, and an authenticity recognition mark is printed on the colored layer of an inside of the light color layers by an infrared absorbing material. A visible light camera photographs a visible light image of the surface printing, and an infrared light camera photographs an infrared image of the internal printing. The inspection device determines the type and authenticity of the gaming chip using the visible light image and the infrared image.

A detection system according to the present invention includes a control device that detects fraud conducted on a game table by using the image analysis result obtained by an image analysis device. In addition, each game token used in this detection system has a multilayer structure having plastic layers with a plurality of different colors stacked on each other, with a colored layer being provided at least intermediately, and white layers or light-colored layers (not illustrated, but may be any layers lighter in color than the colored layer) being stacked on two sides of the intermediate colored layer. As described above, this game token has a multi-layer structure including the colored layer, with the white layers or light-colored layers (not illustrated, but may be any layers lighter in color than the colored layer) being stacked on the two sides of the intermediate colored layer.

A detection system including a control device detecting fraud performed in a game table by using a result of an image analysis performed by an image analyzing device is included. A substitute currency for gaming used for this detection system has a multi-layer structure in which a plurality of plastic layers having different colors are stacked, a coloring layer is included at least in the middle, and white layers or thin-color layers (may be layers having a color thinner than that of the coloring layer; not illustrated in the drawing) are stacked on both sides of the coloring layer disposed in the middle.

The management and control device uses the information acquired from the measurement device to detect a total bet amount of the chips placed on the bet area of the game table by the game participants, and uses the information acquired from the card shoe and the measurement device to detect a winning or losing amount for the game organizer. A sales balance management part compares a sales profit ratio that is a ratio of the winning or losing amount for the game organizer to the total bet amount with a theoretical profit ratio or a previous average profit ratio, and outputs a comparison result.

There is provided a game management system that can manage games using RFID tags built into chips even when multiple types of chips are housed in a chip tray, and a double chip tray used for the system. A chip tray is a double chip tray equipped with a chip tray reader capable of reading two types of chips of different shapes and/or sizes that incorporate RFID tags, namely round chips and plaque chips, an upper chip holder that can hold chips, and a lower chip holder that can hold chips. The chip tray reader is configured to read the RFID tags of the two types of chips held in the chip tray, and is capable of determining the respective amounts.

An apparatus and method directed to a coin-type digital currency device that provides for a portable smart coin that has a universal and variable value with enhanced security features. The coin-type digital currency device is activated for a transaction and placed in a position proximate to a communications device and the communications device is altered that a transaction is awaiting execution. A secure communications link is established between the coin-type digital currency device and the communications device using a combination of RF and optical communications. Once the secure communications is established, the transaction is approved, executed, and registered together with updating the currency balance associated with the coin-type digital currency device.

In accordance with some embodiments there is provided an electronic gaming table system (e.g., a smart table operable to facilitate a card game, such as baccarat, blackjack or poker) which includes (i) at least one detecting mechanism for detecting a plurality of game elements (e.g., wagering chips) placed on, or removed from, a particular physical position of a physical table of the gaming table system to represent at least one wager for a particular game event; and (ii) a game controller operable to identify, based at least on data received from the at least one detecting mechanism, whether the plurality of game elements represent a single wager or multiple distinct wagers placed on the particular physical position and for the particular game event. In some embodiments, the detecting mechanism is an RFID antenna.
