The QR code scanned yesterday is green. Why is it yellow today?

There should be mistakes in big data, because the number of registered people is close to100000, and the system platform is unstable. Now it has been changed into a dynamic QR code. If you refresh the QR code several times, it should turn into a green code. If it really doesn't work, then call the official consultation.

One code communication 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.

Functional characteristics;

The health coding system has formed a set of standards, which can be quickly introduced according to the needs of different regions and the needs of epidemic prevention and control in various places.

In order to promote the mutual recognition of "health code" in different places, the national comprehensive government service platform provides three ways to realize cross-provincial mutual recognition and sharing:

The first is to add the function of cross-regional mutual recognition to the local "health code" through the sharing of cross-regional epidemic prevention and health information data without changing the existing local "health code".

Second, the local "health code" is connected with the national comprehensive government service platform "epidemic prevention information code", and the national comprehensive government service platform "epidemic prevention information code" is used as the intermediary to realize the mutual recognition of cross-regional "health code".

Thirdly, in areas where there is no local "health code", the "epidemic prevention information code" of the national comprehensive government service platform can be directly adopted, and at the same time, combined with local epidemic prevention and health-related information, cross-regional interoperability and mutual recognition can be realized.
