Only Amazon Could Make a Checkout-Free Grocery Store a Reality

On Monday, Amazon took the wraps off Amazon Go, a real-world grocery store that comes with a twist: there's no checkout process. You just grab the stuff you want and walk out; the order posts to your Amazon account afterwards. There are no cashiers, no lines, no fumbling for a credit card. And while experts agree that Go looks very much like the future of retail, it's less clear whether Amazon has all of the pieces in place. Amazon says all you need is the Amazon Go app to enter the store and start shopping.
