Why does the sudden health code of Kexing vaccine show error correction?

1. It may be that the network signal is not good, so that the health code or the normal page cannot be displayed.

2. It may be that the resolution and color matching of the mobile phone cause the health code to be grayed out.

3. The application for new mobile phone number health code may be in the gray code testing stage. According to the current status of users, the latest health risk status is displayed through the background comparison of user registration related data. I suggest you wait for transcoding and stick to punching in. As long as you meet the transcoding rules and are healthy, the system will automatically turn into a green code.
