Schools in Brazil have started to place computer chips in school uniforms to keep track of pupils and reduce truancy.
Some 20,000 pupils in the north-eastern city of Vitoria da Conquista will have microchips embedded in their school T-shirts.
The parents will get a text message when their children arrive at school, or if they are late for classes.
The authorities say the measure will help teacher-parent relations.
