'Smart' uniforms track Chinese students in truancy fight

Paired with facial recognition devices installed on school doors, the smart uniforms can also sense if students swap uniforms.

Schools in southern China are using chip-powered "smart" school uniforms to track their students in a bid to tackle truancy and boost attendance.

The uniforms use chips to monitor the location of students and can record their exit and entry into school, according to the tech firm behind the tracking devices.
