In response to the rising number of imported novel coronavirus infections, an international edition of health QR code system has been developed recently and put into use.

Passengers may use a built-in WeChat program or a mobile phone application developed by China Customs to complete the health condition report, resulting in the end a two-dimensional code. Passengers have to present this code to pass through customs.
