Introducing Amazon Go: No lines, no checkout - just grab and go

Amazon finally 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.
