Looks like the folks at Amazon have taken up palm reading with the recent rollout of Amazon One, a pay-by-palm technology.

Don't like the idea of having to touch "dirty" cash or handing your credit card to a cashier who has handled thousands of other credit cards that day? Maybe you don't like having to carry around a wallet or a purse. Well, then perhaps Amazon One is the solution for you. 

Unveiled back in 2020 in its Seattle hometown, Amazon's palm scanning payment method is gradually gaining steam as the concept takes root on American soil.

How does pay-by-palm scanning work?

Nobody else on earth has the same palm print as you do. Not only are the ridges and wrinkles of your palms individually tailored to you, but so are the veins in your hands and fingers. Amazon's new pay-by-palm technology detects your skin topography and is also able to detect the vein patterns of your hands. [source]
