In three Carroll County elementary schools the old-fashioned an inefficient act of physically handing physical money to a cashier in the school cafeteria has been swapped out for a more modern biometric palm scan โ€” a student holds her hands above an infrared scanner which โ€œidentifies unique palm and vein patterns, and converts the image into an encrypted numeric algorithm that records a sale.โ€

Some find the new system a little too dystopian-chic, and 20 percent of parents have opted out of the program. As the Baltimore Sun reports, the privacy concerns raised by such a system are particularly pointed when you consider the young age of the palm-scanned. Khaliah Barnes, of the Electronic Privacy Information Center, told the Sun, โ€œWeโ€™re talking about elementary school students, and that type of technology can make children less inclined to the rights of privacy.โ€

Infrared palm scanners should make their way into all Carroll County elementary schools within a year and a half.
