METHOD AND APPARATUS PERTAINING TO USE OF BOTH OPTICAL AND ELECTRONIC PRODUCT CODES

摘要

A control circuit accesses information regarding both scanned optical product codes as correspond to items being purchased in a given transaction as well as read electronic product codes as correspond to items being purchased in that same transaction. The control circuit then compares that information to identify discrepancies. An example of a discrepancy of likely interest includes noting items for which there is a read electronic product code but not a corresponding scanned optical product code and vice versa.
