The Amazon One device that allows customers to pay at Amazon Go stores using their palm is being rolled out to additional Amazon stores in Seattle.Amazon One touchless palm-reading tech is coming to the Amazon Go location at Madison & Minor, and will expand to two additional locations “in the coming weeks,” Amazon said. The eCommerce retailer initially rolled out the technology in September as an alternative to harnessing a quick-response (QR) code or app to walk into its automated Go stores. The tech lets shoppers use their palms as an ID and payment method.Amazon revealed last January it was working on new checkout terminals that would allow shoppers to make payments using biometric data found on their palm prints rather than having to whip out a credit or debit card, according to the Wall Street Journal.The report follows a September 2019 report in the New York Post that Amazon was testing hand biometrics technology at Whole Foods stores and for use in vending machines.Amazon filed a patent for technology that could identify you by scanning the wrinkles in the palm of your hand and by using a light to see beneath your skin to your blood vessels. The resulting images could be used to identify you as a shopper at Amazon Go stores.
