In Just Walk Out-enabled stores, shoppers enter the store using a credit card. They don't need to download an app or create an Amazon account. Our Just Walk Out technology detects what products shoppers take from or return to the shelves and keeps track of them in a virtual cart. When done shopping, they can just walk out and their credit card will be charged for the items in their virtual cart. If shoppers need a receipt, they can visit a kiosk in the store and enter their email address. A receipt will be emailed to them for this trip. If they use the same credit card to enter this or any other Just Walk Out-enabled store in the future, a receipt will be emailed to them automatically.
