Texas Students Tracked with RFID

Hoping to prevent the loss of a child through kidnapping or more innocent circumstances, a few schools have begun monitoring student arrivals and departures using technology similar to that used to track livestock and pallets of retail shipments.
Here in a growing middle- and working-class suburb just north of Houston, the effort is undergoing its most ambitious test. The Spring Independent School District is equipping 28,000 students with ID badges containing computer chips that are read when the students get on and off school buses. The information is fed automatically by wireless phone to the police and school administrators.
