The administrating system is configured to recognize whether there is a lost package by comparing the information of all ID codes registered in registering steps with the ID codes at places of packages obtained at the calculating step from the loading step and the unloading step.

A fraud detection system which detects fraud in a game of performing collection and redemption of chips in accordance with a win or lose result includes a camera which captures an image of chips contained in a chip tray of a dealer, an image analyzing apparatus which analyses the image captured by the camera to detect an amount of the chips contained in the chip tray, a card distribution device which determines a win or lose result of a game, and a control device which compares the win or lose result of the game and the amount of the chips contained in the chip tray before and after collection and redemption of the chips to detect fraud.

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.

There is provided a shuffled playing card, wherein a suit and a rank are printed on one surface of a card base sheet, and a back pattern is printed on another surface, different sheet IDs for one card base sheet or each of a plurality of card base sheets are printed on the card base sheet, one deck or a plurality of decks are formed by individual cards cut by a cutting machine from the card base sheet, the one deck or the plurality of decks are shuffled by a shuffle machine to form a set of shuffled playing cards, different shuffled playing card IDs for each set are assigned to the shuffled playing card as ID codes, and the sheet ID of the playing card constituting the shuffled playing card and the shuffled playing card ID are associated with each other in a database.

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 table game system is provided capable of identifying shuffled playing cards used at the time of the occurrence of a problem in a card shoe apparatus, thereby enabling an investigation of the cause thereof or the taking of countermeasures therefor. A card shoe apparatus of the table game system of the present invention includes a barcode reader and RFID that reads a barcode or RFID provided in a shuffled playing card set, thereby reading a shuffled card ID that uniquely identifies the shuffled playing card set. The control unit has further a function of identifying an exposition of the cut card by the card reading unit and memorizing this information as that the shuffled playing card set now being used will have or be changed to the new one. The information of the exposition of the cut card is at least used for identifying an end of the current game using the shuffled playing cards set is currently set in the card shoe apparatus. A control unit further includes a function of identifying specified events that occur during the use of set of the shuffled playing cards at a game table, and of reporting these occurrences of the specified event in connection with a shuffled card ID.
