Facial recognition comes to university

A top university in China is using a facial recognition system to verify the identity of students and staff members entering its campus.

Anyone going through the southwestern gate of Peking University can now have their face scanned by a camera instead of showing their ID card to security guards under a trial run of the system that started on Wednesday. The technology will be installed at all university gates soon.

Some top universities in China restrict the public from visiting their campuses, and students and staff are often required to show proof of identity before they can enter.
