NEW YORK — Wal-Mart Stores Inc. is expanding a test of a new checkout program that allows shoppers to scan items with their smartphones while they're in the aisles and then pay at self-checkout terminals.
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 markets including Dallas, Houston, Austin, Texas; Denver, Portland, Ore., Seattle, and Phoenix.
