Amazon recently introduced its palm-scanning payment system to a Whole Foods store. It is one of the two advanced payment options Amazon has been successfully testing, other being the “Just Walk Out” technology, wherein the customers can shop for products and literally just walk out of the store. When a shopper takes something off the shelf, it’s added to their virtual cart. After they leave the store, they’re charged for their purchases.
The One works differently. Initially, the customer is supposed to insert their credit card into the kiosk and link it with their palm print. Thereafter, every time they make a purchase, they can pay for their purchase by simply holding their hand over the kiosk.
