简介
Across China, health control checkpoints are being used at train and metro stations (as well as in many public and private buildings). This enables temperature checks and the tracing of the movement of people, in case of contact with a suspected COVID-19 carrier. In many taxis, buses and metro carriages, passengers are encouraged to scan a QR code to register their name and contact number, to help with contact tracing.
