It may look like you just walked into a grocery store, robbed it and walked out effortlessly, but really, that's just the future of shopping, thanks to Amazon Go. The new app uses computer vision, sensors and learning techniques to help you enter a store and pay for whatever you needed to buy via the app, without ever standing in a single line. They're calling it 'Just Walk Out Shopping.'

It all started with a large store in Seattle but it looks like this will be the future of convenient shopping moving forward.
