Abstract
A gaming chip that has a circular bar code imprinted thereon so as to convey information about the issuer of the chip, the chip's denomination, and a serial number which can be utilized to verify the authenticity of the chip. A chip validating device rotates the chip while being maintained in a stationary linear position, such that the encoded information is repeatedly passed before a stationary bar code reader. The validator then uses this information to determine the authenticity of the chip, to indicate the denomination of the chip being wagered, and to accept or reject the chip.
