Walmart tests app that lets shoppers skip checkout lines

NEW YORK (AP) — Walmart is bringing back an app that lets shoppers skip the checkout line and pay for items themselves on their smartphone.

It first tested a version of the app, called Scan & Go, in 2013. But it discontinued it after customers said it was confusing to use. The retailer says it learned from the initial test and redesigned the app to make it easier to use.
