US Amazon has just launched an app that lets people sign up for its palm recognition service. The Amazon One app uses a smartphone's camera to take a photo of a palm print to set up an account. Once signed up, you can pay for stuff by using your
hand. The tech uses generative AI to analyze a palm's vein structure, turning the data into a unique numerical, vector representation which is recognized by scanning machines at retail locations. You'll have to add a payment method within the app to
get started and upload a photo of your ID for the purpose of age verification. Beyond payments, the tech is also used as an age verification tool and as a way to enter concerts and sporting events without having to bring along a ticket. There are
obvious privacy concerns here, as passwords can change but palms cannot. Amazon says that all uploaded palm images are encrypted and sent to a secure Amazon One domain in the Amazon Web Service cloud. The company also says the app includes additional
layers of spoof detection, noting that it's not possible to save or download palm images to the phone itself.
