Because the epidemic will appear in the crowd at any time, it is necessary to scan the place code for registration.
The place code is a proprietary two-dimensional code used by personnel to enter key places, and it is an independent identification code generated by the platform for key places. By scanning the place code, all the people entering and leaving the place can be registered automatically, and the health card status of the people entering and leaving the place will be displayed at the same time, so the place code contains the health code, but opening the health code will not display the place information.
