Your own store location code can open the local health code system. There will be a local code in it, which can be saved and printed after saving.
It is more convenient for the masses to travel. By scanning the "location code", you can automatically register personnel information, automatically verify and display the health information of the "health code", and you can quickly pass it at a glance. For the elderly, minors and other groups, family members or peers can use the "peer" function to scan the code to register.
