I see that hand

Schools in a Florida county, a healthcare system in the Carolinas, a bank in Japan: they're all using a digital wallet. Instead of paying with cash or credit card, when you buy a lunch or pay a bill, the veins in your palm are scanned by near infrared light and your transation is completed electronically.

The 3D configuration of hand veins has proven more unique than fingerprints and faces. It's easy, quick and offers less chance of error and fraud. So why do I think of a Red Dward episode where they had to chop off someone's hand to use as ID verification in order to open a door? And, put down that carpenter's tool belt, Harrison. They may need you in yet another Fugitive remake.
