South Dakota college tests fingerprint purchasing technology to replace cash, credit cards

RAPID CITY, S.D. - A South Dakota university is testing new fingerprint recognition technology as part of a pilot program intended to replace credit cards and cash when making purchases.

More than 50 students and faculty members are taking part in the month-long pilot at the state's School of Mines and Technology.

Instead of using cash or credit cards to buy items at two campus shops, users scan their fingers with a device that recognizes their prints and detects hemoglobin in the blood beneath the skin.

That ensures that the finger being used to purchase has a pulse.

Students who've enrolled in the program say their school's role in the testing helps put the 2,400-student university on the map.

The first-of-its-kind pilot has been so successful that university officials are hoping to expand it.
