Amazon releases new cashless "pay by palm" technology that requires only a hand wave

Amazon is taking cashless payments to another level.

In a new rollout, the tech giant is giving customers another contactless way to pay for groceries — with their palms.

In a statement Thursday, Amazon announced that the palm recognition service, called Amazon One, will be used for payment, identification, loyalty membership, and entry at over 500 Whole Foods and Amazon Fresh locations across the nation by the end of the year.
