Walmarts in Gwinnett Using Smartphone Checkout System

And now, a new twist to those self-checkout lanes.

Walmart, the nation's largest retailer, now has an iPhone app that lets you check out via your smartphone. And the process is being used in several Gwinnett locations.

According to media reports and the Walmart website, the app allows shoppers to use their smartphones to scan the barcode of each purchase, place the product in a cart, and then check out by scanning another barcode at the self-checkout lane. Customers won't have to take their groceries out of their carts until placing them in their vehicles.

It's the only such system used by a retailer.

"We know that our customers are technologically savvy. We understand that they want their experience here to be fast.  They want it to be friendly, And we are ready for it," Walmart store manager Katie Wheeler told Fox5 Atlanta.
