Items will be billed through your Amazon account. When you arrive you can enter the gate by (a) scanning the code found under the "in-store" section of the Amazon app, (b) by inserting a credit card linked to your Amazon account, or (c) using your palm if you've set up Amazon One (there's a kiosk in the entrance if you'd like to register). The store tracks what you take and when you leave it will bill through your Amazon account (you can adjust what payment is used before entering) just as if you made a purchase on Amazon's website.
Check in with Amazon Go app and when you leave whatever you bring will be charged
You check in with your palm and there’s a card registered to your name. Grab whatever you want an head out. The tags of what you left with will register at the sensors at the turnstiles and you’ll be charged about two hours later.
