Amazon Brings Palm Print Payment Technology to Whole Foods | Eater

"This Seattle grocery location is piloting a palm-print payment system that links a credit card to a customer’s palm so purchases can be completed by swiping a hand. The system stores biometric data in the cloud (unlike on-device Face ID), raising concerns about exposure to hackers, access by third parties such as governments, and the impossibility of changing a compromised palm print. The rollout will begin near the company’s Seattle headquarters and expand locally; the retailer says it will not enable its cashier-less “Just Walk Out” system at this site to avoid cutting jobs, even as broader corporate practices around working conditions and unionization have been contested. Critics warn that merging physical identity with payment infrastructure threatens privacy and civil rights, while company assurances about data use have been met with skepticism." - Jaya Saxena
