A management system for managing gaming chips, wherein at least one gaming chip of the gaming chips includes a radio frequency identification (RFID) tag that stores a first information, and each gaming chip of the gaming chips has a second information represented on a side surface of the gaming chip, the second information is readable when the gaming chips are stacked on top of each other, the management system comprising:
- an image capture device configured to capture an image of a portion of the side surface of each gaming chip of a stack of one or more gaming chips;
- a reader configured to read a set of RFID tags associated with the one or more gaming chips included in the stack to obtain the first information for each read RFID tag;
- an image analysis device configured to, based on the image and for each gaming chip included in the stack, identify the second information;
- a database in which the first information and the second information for each gaming chip of the gaming chips is associated and recorded;
- and
- a controller configured to inspect, by referring to the database, an association between the first information obtained by the reader and the second information obtained by the image analysis device.
A gaming chip used in a management system, the gaming chip comprising:
- an RFID tag configured to store first information;
- and
