South Dakota Students Testing Fingerprint-Based Payment System
More than 50 students and faculty members at the School of Mines and Technology in South Dakota are part of that pilot programme which uses biocryptology – biometrics and cryptology combined – to allow them to buy items at campus shops.
Users must first set up an account in person, bringing with them identification, banking information and their index fingers. To buy an item, students enter their birthday, as an extra identification step, and then put their index finger into scanner, which encrypts the fingerprint and sends the data over the intranet to a secure system that checks it against their records.
The scan goes beneath the top layers of skin to detect haemoglobin in the blood, meaning a pulse must be detected before the purchase is allowed.
