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.

Currency processing systems, coin processing machines, and methods of imaging coins are presented herein. A currency processing system is disclosed which includes a housing with a coin input area for receiving coins and coin receptacles for stowing processed coins. A disk-type coin processing unit is coupled to the coin input area and coin receptacles. The disk-type coin processing unit includes a rotatable disk for imparting motion to the coins, and a sorting head having a lower surface adjacent the rotatable disk. The lower surface forms various shaped regions for guiding the coins, under the motion imparted by the rotatable disk, to exit channels through which the coins are discharged to the coin receptacles. A linear array of sensors is mounted to the sorting head and/or the rotatable disk. The sensors examine each coin on the rotatable disk and output a signal indicative of coin image information for processing the coin.

An inspection system inspects gaming chips each having a color or a display indicating a value on an outer surface in a state where the gaming chips are stored in a case in which a maximum of the number of gaming chips to be stored is limited, and a radio tag storing gaming chip information is embedded in each of the gaming chips. The gaming chips are stored in the case capable of containing a row of gaming chips stacked in a thickness direction, and the inspection system includes a reading device that reads the radio tag of the gaming chip in the case and acquires gaming chip information of the gaming chip and a determining unit that compares the gaming chip information with a maximum of the number of gaming chips storable in the case and determines an abnormality of the gaming chip in the case when the number of gaming chips obtained from the gaming chip information is different from a maximum of the number of storable gaming chips.

The present disclosure relates to a method for identifying a coin, and more particularly, to a coin identifying method capable of simultaneously identifying a type of coin and whether the coin is defective. In the coin identifying method of the present disclosure, since the type of coin and whether the coin is defective are simultaneously determined, there is an advantage that efficiency and reliability of identification can be improved.

The present disclosure is related to an inspection system capable of inspecting a plurality of gaming chips. A game chip of the plurality of game chips includes a wireless tag storing first chip information and to which the optically readable second chip information is on a side of the game chip. The inspection system includes an inspection device configured to inspect one or more game chips. The inspection device includes a wireless tag reader configured to read the wireless tag of the game chip and acquire the first chip information. The inspection device includes a camera configured to reading the side surface of the game chip to obtain the second chip information. The inspection device includes a unit configured to determine whether the game chip passes one or more rules based on the first chip information and the second chip information.
