Amazon Go checkout-free stores incorporate patented technology developed internally by the company.  Amazon now intends to market the same installations for retailers incorporating cameras and sensors to allow cash-free and checkout-free shopping.  The system will require customers to insert a credit card on entry. Receipts are E-mailed following completion of the purchase.

The first Amazon Go cashierless convenience store was opened at the beginning of 2018 and the technology now operates in an Amazon Go grocery commissioned last month.
