Walmart Testing iPhone Checkout App

System would presumably speed up checkout

Wal-Mart Stores Inc is testing a system that would allow shoppers to scan items using their iPhones and then pay at a self-checkout counter, a move that could trim checkout times and slash costs for retailers.

If the "Scan & Go" test by the world's largest retailer is successful, it has the potential to change the way people shop and pay, making the process more personal and potentially faster.

Earlier this week, Walmart invited employees with Apple Inc iPhones to participate in a test at a Walmart supercenter in Rogers, Arkansas, near the company's headquarters, according to a form on the Survey Monkey website.
