Due to the need of epidemic prevention and control, scanning code and plain code have become the standard of people's daily travel. When entering and leaving public places, people need to use smart phones to scan QR codes, such as health codes, travel codes and location codes. However, this has become a problem for many elderly people and children who can't or can't use smart phones. In order to help solve the difficulties of the elderly in using intelligent technology, the Provincial Big Data Administration has introduced the function of "exporting health codes" on Hainan health codes by using digital technology.
Users can export the health code certificate on the Hainan health code page, download and save it to the mobile phone photo album or print it out and carry it with them. When entering or leaving public places, they can show the health code certificate to the verifier, and the verifier can use the "scan" function of Haiyi Office App, WeChat or Alipay to check the health status of the code holder. In order to ensure the security and privacy of user data, the display page is desensitized information, and the verification result is consistent with the online "Hainan Health Code".
