TechWatch: Walmart Testings Scan As-You-Go Checkout Program
Walmart is testing the next innovation in self-checkout. It's an iPhone app called Scan & Go. You scan and items as you put them in your cart while walking the aisle, then head to the self-checkout aisle where your list is already waiting to be paid for, meaning you are able to avoid both a checker and the scanning process at the bottleneck that is the checkout area.
