The code of Shanghai Health Cloud is valid on the same day, 24 hours, and can be reapplied after expiration.
After registering health information in the "Health Cloud" APP, citizens will get a health dynamic code of personnel management classification, and the color they get will be different according to their personal situation. The black and white code indicates that you can travel normally. The red code can be changed to black-and-white code after medical management measures are lifted, discharged from hospital and suspects are excluded, and the yellow code can be changed to black-and-white code after centralized or home isolation 14 days after entering Shanghai, and the health records can be filled in continuously.
Citizens enter the "Prevention and Control Service Area" through the "Healthy Cloud" App or the "Shanghai Healthy Cloud" WeChat service number, and can view the corresponding health dynamic code after real-name authentication.
Managers in enterprises, communities and public places can use the "code scanning verification" function on the homepage of "Health Cloud" App or the QR code scanned by WeChat and Alipay to verify the health information of people entering and leaving the community, employees when the enterprise returns to work, people entering and leaving public places and patients when medical institutions see a doctor.
