Patent Nos. 5,382,779 and 5,493,107
Shelf Price Label and Product Placement Verification Apparatus And Method
Issued: January 17, 1995 and February 20, 1996
Inventor: Om P. Gupta, Ithaca, NY
Assignee: Digicomp Research Corporation, Ithaca, NY
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. The method and apparatus described herein are easily adapted to allow government inspections of stores for shelf price accuracy.
The later patent, a continuation-in-part, adds the capability to check that the product matches the shelf price label, and warning the operator if there is a mis-match.
