How have schools used the technology to monitor children on buses?
A few schools have used radio frequency identification to confirm that each student gets onto and off his or her bus at a specific stop, including the Tucson Unified School District (see Tucson Schools Considering RFID BusPass). The idea is to read a tag associated with each student as he or she boards the vehicle, and to send an SMS text message to that child’s parents. When the student exits the bus, the parents are again notified.
Ideally, GPS is used on the bus as well, and the system can then show the exact location at which every student exited. This use of the technology has not been widely adopted, however. One reason is that some parents object to their children having to wear an RFID tag. For more on this topic, see How Can a School Monitor Children in Buses and Classrooms?
