Amazon announced today through a video posted online that it's testing a grocery store in hometown Seattle that has no checkout process, much less checkout lines. The store, dubbed Amazon Go, requires customers to launch a QR-code based app, which they scan upon walking into the site. The retailer's “Just Walk Out” technology detects when products are removed from or returned to shelves, keeps track of them in a virtual cart, and totals the cost when customers depart the store.
