Abstract: A fully automated accounting system accurately and automatically monitors and records all gaming chip transactions in a casino. The system employs a gaming chip having a transponder embedded therein and has an ongoing and "on-command" ability to provide an instantaneous inventory of all of the gaming chips in the casino, including those in storage in the vault as well as the chips in the cashiers cage and at each gaming table on the casino floor. The system is capable of reporting the total value of the gaming chips at any location, as well as the value of any particular transaction at any gaming table or at the cashiers cage. Optionally, the transaction history of each chip may be maintained in a data base embedded in the chip (or alternatively in a central computer), and read each time the gaming chip is scanned by a special antenna.

Abstract: A method of tracking movement of gaming chips in casino comprising gaming chips each having an electronic circuit which transmits information, and antennas located at gaming chip placement areas. When gaming chips are placed on a first gaming chip placement area within the casino, the antenna at that first gaming chip placement area transmits a radio beam which in effect scans the electronic circuits of the gaming chips. The electronic circuits identify the gaming chips by electronically broadcasting information. Upon moving a first of the gaming chips to a second gaming chip placement area, the antenna at the second gaming chip location transmits a radio beam which scans the electronic circuit of the first gaming chip. The electronic circuit in the first gaming chip identifies the first gaming chip on the second gaming chip placement area so that the location of the first gaming chip is tracked. The gaming chip placement areas may be at various places such as on a gaming table or a gaming chip tray.
