A state college in South Dakota is trialling a new high-tech way to purchase goods using fingerprints.
The technique uses Biocryptology, a cross between biometrics and cryptology that provides a safe and secure way to buy things using nothing more than a scan of someone's fingerprint. What sets this system apart from other fingerprint scanning concepts however is that it safeguards against a common workaround often seen in movies whereby a villain removes someone's finger and presses it up against the scanner.
The trick is to have the scanner also check to make sure that the finger being used is actually attached to a living person by measuring the blood flow underneath the skin. This means that in the future if someone did try to steal your money by chopping off your fingers they still wouldn't be able to do so.
"Futurists have long proclaimed the coming of a cashless society, where dollar bills and plastic cards are replaced by fingerprint and retina scanners smart enough to distinguish a living, breathing account holder from an identity thief."
