Facial recognition systems launched in all metro stations across central China's Zhengzhou

Facial recognition scanners have been launched in all metro stations across central China's Zhengzhou city on December 3.

In the video, a man scanned his face in front of a facial recognition device in order to make the station gate open.

In September, Line 1 and Line 14 of the Zhengzhou Metro started to use face-scanning check-in service and it has now been applied to all metro stations in the city.

Commuters can register and open the face-scanning service on Zhengzhou Metro's official app. Once they scan their faces to enter the subway, the fare will be automatically deducted from the -set payment method.

Zhengzhou is the first Chinese city to use the face-scanning check-in service in the metro.
