Moscow’s facial-recognition surveillance cameras are now being deployed by collectors to track down debtors, the city’s chief bailiff told state media on Wednesday.

The Russian capital claims one of the world’s largest facial-recognition systems, with 174,000 closed-circuit TV (CCTV) cameras expected to be in operation this year. In 2018, personal loans in Russia grew by 46 percent compared to 2017, amounting to 8.6 trillion rubles ($130 billion).

“We can now trace the debtors’ movements” thanks to this sprawling network, Sergei Zamorodskikh, the head of the Federal Court Marshals Service’s Moscow branch, told the state-run TASS news agency.
