The world's largest retailer launched what it calls its "Scan & Go" program late last year in about 70 stores in Atlanta and in the Bentonville, Ark., area, where the retailer is based. It is now testing the program in more than 200 stores in other markets, including Dallas, Houston, Austin, Denver, Portland, Seattle and Phoenix.
The pilot program will still be in a small number of Wal-Mart's more than 4,000 stores in the U.S. But it's part of the company's overall strategy to involve customers' increasing use of smartphones.
