SYSTEM AND METHOD OF VERIFYING GRAPHICALLY DISPLAYED RELATIVE INFORMATION

An electronic price label relative information verification system which ensures that first business information for an item is equal to second business information assigned to the electronic price label for display. The system includes a computer system coupled to the electronic price label, including a terminal and a storage medium coupled to the terminal. The storage medium contains a data record for the item, which contains identification information and a verifier for the item. The computer terminal obtains the first relative information for the item from the business information source, calculates another verifier from the first relative information for the item, reads the data record to obtain the one verifier, compares the one and the other verifiers to determine whether they are equal, and changes displayed business information to the first relative information if the one and the other verifiers are different.
