Wechat health code cannot be used. First of all, it may be caused by the mobile phone network. This may happen if the mobile phone has a poor network speed or no network connection. Users are advised to check the network connection status of the mobile phone, or disconnect the mobile phone network and try again. General problems can be solved.
Characteristics of health laws and regulations
The health code was launched by Alipay and WeChat, which provided a very convenient special voucher for epidemic prevention and control and information tracing during the epidemic. At present, it has also been popularized and applied in many provinces.
Health codes are mainly based on real data. We can apply through Alipay or WeChat, and generate our own QR code after background review. After the QR code is generated, we will judge our health status according to big data such as our activity trajectory, activity location, public transport we have taken and consumption records.
