The world’s most beautiful subway system is set to become one of the planet’s most high-tech, with Moscow Metro head of security revealing that passengers will soon be able to pay for rides with their faces before the end of 2021.

According to Andrey Kichigin, as reported by Interfax on Tuesday, the Russian capital will implement ‘FacePay’ technology later this year. Currently in testing, it will be available for use at both turnstiles and cash desks. Thus far, test participants have successfully passed through the barriers 2,000 times.

Facial recognition cameras were installed in many metro stations through Moscow last year and are located at payment gates. Although the public cannot yet use the system, it has already been used to catch more than 900 criminal suspects, with the technology also performing a second function of identifying those wanted by the police.
