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.Field of SearchSYSTEMS CONTROLLED BY DATA BEARING RECORDSWith vending RECORDS Particular code pattern Optical Conveyor or chute Having means to test physical characteristic of check CHECK, PER SE INCLUDING MEANS TO TEST VALIDITY OF CHECK Having means to test surface configuration INCLUDING SPECIFIC CHECK PASSAGEWAY (E.G., CHUTE DETAIL, ETC.)
