(CNBC) Amazon is expanding its palm-scanning payment system to a Whole Foods store in Seattle, the company announced Wednesday, the first of many planned rollouts at other locations.
Amazon One, which debuted in September and is currently in use at about a dozen Amazon physical stores, allows shoppers to pay for items by placing their palm over a scanning device. The first time shoppers use the kiosk, they have to insert a credit card to link it with their palm print. But after that, shoppers can pay simply by holding their hand over the kiosk.
