You can buy a metro ticket with your face – but at what cost?

Moscow metro pilots facial recognition ticketing.

Everyone knows the pain of losing your metro ticket and having to line up behind tourists at the station gates as you rush to meet a train. Moscow Metro recently announced a trial of facial recognition called FacePay on the Filevskaya metro line. 1000 commuters are participating in the trial, and the process is simple.

Users install the Moscow Metro app, then upload a photo of their face and link a bank card to pay. To enter the station, they approach dedicated turnstiles with a black round sticker on the floor and look into a camera. The turnstile opens within 1-2 seconds, and the cost of travel is deducted. But is the option to catch a train without opening your wallet or an app worth having your face stored in a database?
