Japanese Banks

This is a palm vein recognition system at Mitsubishi Bank. While these recognition systems have been in place for a while, I notice more of these types of units being used to gain access to your money or pay for goods.

Each of us has a unique vein pattern which the scanner scans to identify you. While its extremely convenient, I can see a new type of crime on the horizon.
Pick pocketing of credit cards will become a thing of the past as body part theft takes over. An evil person doesn't even have to know your pin number - all they need do is cut off your finger or hand to get access to your money.
Can you imagine what would happen when they introduce retinal or even genital scans?

Would you use a part of your body to gain access to your money?
