Abstract
A shelf tag verifying apparatus having a portable terminal unit in radio communication with a base station and in acoustic wave communication with a nearby bar code reader. The bar code reader reads a bar code printed upon a product which rests upon shelving marked by a tag requiring verification. A decoder mounted within the bar code reader generates a binary product code corresponding to the bar code and appends a check code. A SAWR transmitter then transmits the binary product code and the check code to an ASH receiver mounted in the terminal unit. A microprocessor mounted in the terminal unit verifies the check code and generates a query for radio transmission to the base station, whereupon the base station responds with information for verification of the shelf tag.
