Amazon has unveiled technology that lets shoppers at physical stores pay for their purchases by scanning the palm of their hands.
The firm has been experimenting with payment options, including the use of "just walk out" technology, which taps sensors and cameras to track what items customers take from the shelves and then automatically charges through an app.
Now it has unveiled a new option, Amazon One, which uses "custom-built algorithms and hardware" to create and read a person’s unique palm signature. To sign up, users insert their credit card and then hover their palm over the device.
Initially, the system will be used at select Amazon Go stores… However, Amazon plans to extend the rollout and also wants to sell to third parties, arguing it could be used for everyday activities like paying at a store, presenting a loyalty card, entering a location like a stadium, or badging into work.
