With facial recognition and 170,000,000 CCTV cameras already installed (400,000,000 more are on the way), China is really keeping track of its citizens.
I assume, with cameras at various entry points to the country, they're keeping track of visitors too. Just take a snapshot as they enter and put it in the system.
