ABSTRACT:
An electronic price label (EPL) price synchronization system and method which increase price reliability while conserving system bandwidth. A storage medium contains an audit file containing scheduled price change messages. The storage medium may additionally contain an EPL data file containing correct price information or a price file containing correct price information. A computer terminal reads the audit file to obtain an item identification number for an item associated with the EPL from a price change message addressed to the EPL, determines the correct price of the item from either the EPL data file or the price file, sends the correct price information to the EPL, receives a comparison result from the EPL following comparison of the correct price information to displayed price information by the EPL, determines from the comparison result whether the displayed price equals the correct price, and if the correct price is not equal to the displayed price sends another price change message containing the correct price to the EPL.
