Guangdong citizens no longer need to worry about proving their identities, even if they don't happen to have their ID cards on them.

On April 19, Guangzhou police unveiled an identity authentication app that enables citizens to prove their identities via their mobile phones. To date, the city has authorized 20 offices to help citizens register for the service. Once they register, they can use facial recognition technology, available via the app, to prove their identities whenever and wherever necessary.

Developed by police in the Nansha district of Guangzhou, the app provides highly accurate results while at the same time protecting against personal information leaks.
