What is a health code?
Health code is an exclusive two-dimensional code generated based on real data. Electronic certificate, who came in and out during the epidemic, mainly applied through Alipay and WeChat. The appearance of health code avoids the tedious process of personal health examination, facilitates users to distinguish risks directly from the color of health code, and reduces the probability of infection. It is worth noting that the health code is a dynamic code calculated in real time, and screenshots and printing cannot be used normally. If the health code turns yellow or red, you need to reduce travel, isolate yourself, and wait for the background data to be updated. The health code cannot be manually intervened and modified.
