When checking out at Walmart, the process may now become simpler. Walmart is testing a new “Scan & Go” feature on the iPhone. This would allow users to scan and immediately bag items on their shopping list. The purchase could get finalized at a self-checkout counter. Scanning the items with the iPhone would create a list that would be reflected at the automated payment process check-out lane. How the system would work is not yet known. Walmart friends and family were asked to test out the new app as part of an hour-long trial run.
