Nov. 28—At schools in Pinellas County, Fla., students aren't paying for lunch with cash or a card, but with a wave of their hand over a palm scanner.
Students take about four seconds to swipe and pay for lunch, Art Dunham, director of food services for Pinellas County Schools says, and they're doing it with 99% accuracy. Palm-scanning technology is popping up nationwide as a bona fide biometric tracker of identities, and it appears poised to make the jump from schools and hospitals to other sectors of the economy including ATM usage and retail.
