Preschoolers wear tracking devices

Preschoolers are wearing tracking devices at a center run by Contra Costa County near Oakland.

When at the school, students will wear a jersey that has a small radio frequency tag. The tag will send signals to sensors that help track children’s whereabouts, attendance and even whether they’ve eaten or not.

School officials say it will free up teachers and administrators who previously had to note on paper files when a child was absent or had eaten.

County officials claim the system, funded by a $50,000  federal grant, could pay for itself within a year.  If they’re spending $50,000 a year taking attendance, they must be paying staffers a lot of money.
