Vein Vending Machines - Purchasing With The Point Of A Finger
Hitachi's proprietary biometric authentication system requires that users first register an account (probably linking their vein pattern to a credit card), but it allows one to purchase, say, a delicious can of green tea or icy cold black coffee by inserting a cautious hand into a machine for a quick scan.
Of course, the system exploits your identity a bit in the process, using age and gender information stored in a mass networking database file to display an appropriate video ad while you enjoy your refreshment. But hey, if a public Coke machine light-probing your innards doesn't bother you, why should a quick sales pitch?

In theory, any retail outlet, hooked up to this network database and a fingerscan device would allow transactions with a proof of an ability to pay. Supermarkets, gas stations, and other common purchasing environments, when combined with technology, would bring about a cashless, cardless buying society.
If this ID through a tip of a finger thing catches on, it will bring about a whole new meaning to the phrase/term Point-Of-Sale.
