What is the green code of Xi 'an?

Xi 'an implements one code communication, the green code is the two-dimensional code, and the middle is the green area. The determination of "red, yellow, green" tricolor code is dynamically changed based on the analysis of big data in the background of the system. For those who apply for red team or yellow code, the reason may be related to the fact that the confirmed or suspected cases are in the same space; It may be related to coming from key areas. After related separation and nucleic acid detection, the red code of Xi 'an code can be changed from yellow code to green code after the nucleic acid detection result is negative. People with green codes can travel freely in the city, so they need to do personal protection and cooperate with temperature detection. For those who apply for red team or yellow code, the reason may be related to the fact that the confirmed or suspected cases are in the same space; It may be related to coming from key areas. The color of "One Code Pass" will be updated automatically. In the short term, health code and one-code communication are undoubtedly aimed at eliminating the waste of social resources caused by repeated isolation and multiple isolation, ensuring employment and realizing the resumption of work and production. In the long run, relying on the "health password" of big data and cloud computing may become a powerful driving force for social governance after the epidemic.
