Abstract
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. If the chip is not where it is supposed to be according to its recorded transactional history (for example, a vault chip shows up on a gaming table without having passed through the cashiers cage), it will be identified and may be invalidated by nullifying a special casino security code.
