What happens when the health code turns black?

As a health system for epidemic prevention and control, health code usually includes three types: green code, yellow code and red team, and there is no code black. If the health code of residents turns black in life, it is considered that it is caused by the following reasons:

1. The health code applied by the user is under review.

2. The local network is poor and the image is not refreshed.

3. The user failed to authenticate successfully or failed to authenticate.

Note: If the resident health code suddenly turns black, it is likely that the user's mobile phone has no location service and the network is not good, resulting in the inability to update the health code. At this time, turn on the mobile phone to locate and refresh the network data several times to recover.

Health code access information:

Health code traffic information comes from data collected by the state. After prevention and control rules, data modeling and background comparison, three COVID-19 risk levels are judged and displayed in three colors: green, yellow and red.

After individual application, if it is a confirmed, suspected or asymptomatic case, the system will automatically issue a red team. The system compares the health code application of close contacts or individuals, reports it as unhealthy, and the system will automatically issue a yellow code. System comparison does not belong to the "five categories of personnel" (confirmed, suspected, asymptomatic, close contact, fever), and will automatically issue a green code.

Health code is strictly controlled from the aspects of network, application and data mode, and personal information is strictly encrypted and desensitized. The staff can only obtain the color and inspection information of the health code by scanning the code, and the design of the code scanning function fully considers the protection of personal privacy.
