Amazon's new store may be the future of easy

Amazon is testing a grocery store in downtown Seattle that lets customers walk in, grab food from the shelves and walk out again, without ever having to stand in a checkout line. Customers tap their cell phones on a turnstile as they walk into the store, which logs them into the store's network and connects to their Amazon Prime account through an app. The service is called Amazon Go. It uses machine learning, sensors and artificial intelligence to track items customers pick up. These are then added to the virtual cart on their app.
