To ensure that kids don't get off at the wrong stops, some school districts have started using fingerprint and card scanners to track students who ride school buses
. The Desert Sands Unified School District, located just north of San Diego, began testing a Biometric Observation Security System (BOSS) on its buses earlier this month, according to USA Today. Students simply touch their fingers to a tiny screen when they get on and off the bus; if a child tries to get off at the wrong stop, BOSS sounds an alarm to notify the driver. About 30 school districts across the country, including ones in Missouri and Illinois, have begun using a similar system called ZPass. Instead of a fingerprint, the system uses an electronic card that's tethered to a child's backpack.
Of course, "tracking kids" is a phrase parents don't want to hear. But Global Biometrics Security president John DeVries, developer of BOSS, told USA Today that the system doesn't store kids' fingerprints. Instead, the image is converted to a series of numbers that cannot be used to recreate the original print.
