Jinan opens first 3D facial recognition metro line

Metro Line 1 in Jinan city, Shandong province has become the first in China to adopt 3D facial recognition technology.

After uploading their facial information via an app for the metro line, passengers can simply face a device at the entrance and pass the turnstile within two seconds.

The error rate is said to be only one in 1 million, while the technology can also detect fraudulent use of photos, videos or masks.

The 3D facial recognition technology-empowered gate can allow entry of 30 to 40 passengers per minute, a great boost to efficiency, said a staff member.
