How a university campus is using facial recognition to keep its dorms safe

Female undergraduates at a top Chinese university can now use their face to open doors. The Beijing Normal University installed two facial recognition devices at entrances to the No. 13 female dorms in early May this year, according to state-run Beijing News.

If the system does not recognise a face, it will alert security. Students can either swipe their student ID, key in their ID number, or say their name; the system then runs their face through a database and unlocks the door for residents it recognises.
