Palm scanner speeds up line at Fla. school

Takes about four seconds for students to swipe.

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.
