The Week:

Walmart is test-driving a system that could dramatically change the way Americans shop. The program, called Scan & Go, lets customers scan their own goods with their smartphones then pass through a self-checkout line, and zip out of the store. The company recently conducted a trial run with employees and their friends and families at a Walmart Supercenter in Rogers, Ark., not far from the retail giant’s Bentonville headquarters. If all goes well, the nation’s largest retailer could begin rolling out Scan & Go nationwide. Is this the future of shopping?

Does this idea remind you of this old commercial from IBM? It does me.
