Yes. You need to have the Amazon Go app installed on your phone, and you scan your phone at what looks like a turnstile to enter the store, from the store's PR videos. Then the store keeps track of what you pick up using computer vision, your phone and various sensors, and charges everything you walk out with to your account.

Unless you can avoid the requirement to load an app and scan it to get into the store, walking out of the store with goods stuffed in your jacket or bag isn't shoplifting, because the store knows you picked those things up and is charging them to your Amazon account.
