Cashless Biocryptology: Your finger may soon replace your credit card; will come with an added security layer

Rapid City — 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. Two shops on the School of Mines and Technology campus are performing one of the world’s first experiments in Biocryptology – a mix of biometrics (using physical traits for identification) and cryptology (the study of encoding private information). Students at the Rapid City school can buy a bag of potato chips with a machine that non-intrusively detects their hemoglobin to make sure the transaction is legitimate.
