Yahoo Autos Amazon's palm-reading tech is being tested in Panera cafes
The technology also works for MyPanera loyalty points.
Amazon One's palm-reading technology that can substitute for credit cards and tickets is now available for Panera customers. With this new partnership, the fast casual chain becomes the first national restaurant to let diners use their palm for payments and loyalty points.
To purchase food, customers will first need to link their MyPanera membership with an Amazon One account. This removes the need to hand over a phone number at the checkout, which traditionally provided the server with available rewards. Palm scans can be used to access loyalty rewards, for payment, or for both.
