Through the data sharing of cross-regional epidemic prevention health information, the cross-regional mutual recognition function is added to the local "health code". The second is the connection between local health code and national comprehensive government service platform "epidemic prevention information code", which is transformed through the intermediary of national comprehensive government service platform "epidemic prevention information code".
So as to realize cross-regional mutual recognition of "health codes". 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.
On February 28th, 2020, Shanxi Province launched the Health Code. So far, more than 200 cities in China can apply for health codes in Alipay. Among them, Zhejiang, Sichuan, Hainan, Chongqing, Shanghai, Yunnan, Shanxi, Hubei and other provinces and cities have achieved full coverage. Alipay revealed that with the increase in demand, it will resume production in an orderly manner.
While the coverage of urban health codes is further expanded, the application scope is also expanding. Due to different prevention and control situations, there are differences in coding rules and application scope of local governments. Zhejiang province has the most extensive application scenarios, and the number of people receiving codes is far ahead.
