To enter the Beijing Train Station everyone has to pass by the Face recognition machines, scanning their ID papers first, then having their face scanned to make sure they are who they say they are. Big brother is watching. Above the entrance to the station are instructions how to do thisd process oneself, without help from staff. Buying tickets for travel at ticket machines, again one has to scan documents. Anyone who has a low social credit rating may not be allowed to travel, or even enter the railway station.
