Facial recognition technology has been installed in all metro stations in the Russian capital. Metro riders now have the option to pay using only facial recognition, dubbed Face Pay, according to a series of tweets from Moscow Mayor Sergey Sobyanin.

To use the software, passengers must upload their photo, bank card and Troika card to the Moscow Metro application. After this step is complete, passengers pass through the facial recognition turnstile by looking at the camera.

Other current payment methods will remain in effect.
