VeinID technology at vending machines

Looks like you might be able to purchase a can of Coke using nothing but your finger the next time round, thanks to Hitachi’s “finger vein authentication” (VeinID) technology. This biometric system will rely on finger pulse recognition to find out your identity, and is safe, convenient and efficient since there aren’t any more pesky passwords or PIN numbers to remember – just place your finger and voila! If you happen to have enough credit left in a linked bank account, an ice cold can of Coke will automatically pop out. Makes us wonder whether fingers from cadavers will suddenly see an increase in price in the black market if such technology catches on to cover more than just vending machines.
