Why scan when you can use application code to tune it out?

The reason for this is the following:

After each application code is generated, the update time is displayed, and personal photos can be viewed.

In addition, the application code also provides verification function. As a verifier of the scene application, he can also take out the mobile phone scanning application code for verification.

In order to cooperate with inspectors to do epidemic prevention work more strictly, sometimes the code will be scanned again at the verification site.
