The pattern of veins inside your finger is said to be more unique than your fingerprint, and is being heralded by some experts as a more secure alternative to the chip and pin (Personal Identification Number) card system currently favoured by British banks. Electronics giant Hitachi already manufactures a PC-compatible finger vein scanner, which is about the size of a computer mouse and contains LED lights and a video camera.

Currently retailing online for £195 plus VAT each, they are not a cheap option. "It is the fastest and most accurate technology we've seen to date," said Roberto Fiorentino, chief executive of British firm Croma Security Solutions, which has fitted finger vein-based security systems in UK hotels, airports and most recently a police armoury. "I have no doubt we will see this technology operating in banks - and perhaps cash machines - in the UK High Street in the future."
A trial currently underway at Southampton General Hospital's intensive care ward has so far shown that health conditions such as high and low blood pressure do not seem to affect a patient's finger vein pattern to the extent that they become unrecognizable.
