> To be able to use it, commuters register in the Moscow subway app, upload a photo of their face, and attach their bank card. Once the user approaches turnstiles, the camera recognizes the face (even if the person is wearing a mask), the fare is debited from their account, and the pay gate opens. The whole process takes two or three seconds. But customers can still pay the old-fashioned way, too. What strikes me as odd here is that the user only uploads a picture and that the system also works if the user is wearing a mask. How accurate can such a system be considering you can’t even make out a shape of the person’s face or with many masks even the bridge of the nose?
