If you’ve ever wanted to pay for groceries with the touch of a finger, look no further than the South Dakota School of Mines and Technology in Rapid City, South Dakota.
Two locations – a coffee shop and convenience store – on the school’s campus recently began testing fingerprint purchasing technology that allows students to buy goods with their fingerprint. The technology is called Biocryptology, and not only does it identify a person’s unique fingerprint, but detects levels of hemoglobin, or the oxygen in red blood cells, to make sure the person has a pulse. Thus, criminals looking to fool the system with severed fingers will be unsuccessful (yes, the developers thought of that).
