Patent granted on: Tue, 20 Feb 1996
A price verification method for retail stores using shelf pricing, and apparatus therefor, in which the shelf labels are provided with an extended bar code having the item number and price of the item. A remote unit scans the item number and price, and uses the item number to look up the item in a database which is identical to the store checkout scanner database, and compares the shelf price to the database price. If they are not the same, a new shelf label may be printed immediately. Also, the UPC or other barcode on the product itself is scanned and compared to the shelf price label.
