Chongqing authorities have introduced facial recognition technology for marriage registration to make the procedure easier and shorter, Xinhua news agency reported on Sunday (Jan 7).

The Marriage, Adoption Registration Management Center of Chongqing said the system was launched this month and it can also process marriage registration between Chinese citizens and foreigners.

The system can also deal with cases in which applicants have had plastic surgery or twins who can be differentiated via fingerprints, which were difficult for previous artificial recognition systems.
