An electronic price label (EPL) promotional information verification system (10) which ensures that promotional information for an item obtained from a promotional information file (46) is equal to other promotional information displayed by an electronic price label (EPL) (22) for the item. The system includes a computer system coupled to the EPL (22), which includes a computer terminal (24) and a storage medium (26, 44) coupled thereto containing an EPL data file (32), containing EPL identification information and an EPL promotional information verifier. The computer terminal (24) executes a verification program which compares promotional information or verifiers, possibly in the form of checksums, associated therewith, held by the EPL data file (32) and the promotional information file (46) and changes displayed promotional information to that held by the promotional information file (46) if they are different. <IMAGE> |
