Patent

CA 2169908

An electronic price label (EPL) price verification system which ensures that a price for an item obtained from a price look-up (PLU) file by a bar code scanner is equal to another price displayed by an electronic price label (EPL) for the item. The EPL price verification system includes a computer system coupled to the EPL, which includes a terminal and a storage medium coupled to the terminal. The storage medium contains an EPL data file, which contains EPL identification information and an EPL price verifier. The computer terminal executes a price verification program which reads the PLU file to obtain the price of the item, calculates another price verifier from the price of the item in the price file, reads EPL data file to obtain the one price verifier, compares the one and the other price verifiers to determine whether they are equal, and changes the displayed price to the price in the PLU file if the one and the other price verifiers are different.
