How can the elderly display the health code without a mobile phone?

If the elderly don't have a mobile phone, family members or caregivers can download and register the health code, and then fill in the health information of the elderly. When it is necessary to show the health code, family members or caregivers can show the health code to prove the health status of the elderly. If you don't have the help of your family or caregivers, you can seek help from the local community or government departments.
