West Cheshire College, UK, have active RFID chips in students lanyards for a registration and building management Real Time Location System that enables the college to pinpoint the students precise position on the premises.
This location system enables the college to search for students and staff “in groups, such as peer groups.” It is unclear whether students are tracked to personally sensitive areas, such as showers, school nurse, etc.
Here is a short 2 minute promotional video of the RFID system, thought to be the first of its kind used in education in the UK.
