BENTONVILLE, Ark. -- Wal-Mart officials last week began testing a state-of-the-art electronic product code identification system at a Sam's Club store in Tulsa, Okla.
The test of the new electronic product code system is designed to increase the tracking capabilities of products as they move through the supply chain. It is part of an extensive research program currently being conducted at Massachusettts Institute of Technology's Auto ID-Center in Cambridge, Mass.
