The difference between static code and health code

The static code of health code can only be used for identity confirmation and has no other function. There are two kinds of health codes: dynamic code and static code. Among them, dynamic codes are used frequently, especially during the current epidemic, and you have to show your own dynamic codes every time you go. However, static code also exists. Static code can only reflect personal identity information, and does not have the function of proving health. The static code of electronic health code can only be used as the authentication of personal identity information, and has no other use.
