Pay the bill with the palm of your hand.
It is the latest Amazon revolution, which launches Amazon One, a biometric technology capable of transforming the hand into a credit card by creating a sort of composite "palm signature" that brings together veins and lines of the palm.
The novelty, which will debut in Amazon's physical stores, allows you to pay by passing the palm of your hand, previously connected to a credit card, on a special scanner.
Amazon not only intends to use the new technology in its stores, but also to sell it to third parties, such as stores, stadiums and offices.
And in this regard it has already started negotiations with some potential customers.
