The black health code indicates that the electronic card application has been submitted and will be issued, or indicates that the health code system is under review. It is also possible that the health code in the user's area has no color difference and can only be scanned normally. Although the health code is only a two-dimensional code, it contains rich data information. It is an individual who enters and exits the local electronic certificate, realizing a declaration, which is universal in the whole city.
