You can only apply for a health code with your own mobile phone. As long as your grandson has a mobile phone, every unit in your community will have a QR code of the health code. You can download and install it by scanning it with your mobile phone. Enter your real name, ID number, mobile phone number and real address when installing. Now you need to brush your face to recognize your face, read the numbers aloud, and the installation is complete.
Detailed explanation
At present, the whole country has basically achieved "one-code communication". The next step will be to further promote and improve the management of health codes to ensure that the national policies and standards for health code management are consistent. At the same time, we will actively promote the automatic integration of information such as nucleic acid testing, vaccination and whether we have been to high-risk areas into health codes through technical means, without filling in the information ourselves. These works are being carried out in various places.
Improve the use of health codes by special groups such as the elderly and minors. Health codes in all places should be handled by relatives and friends, and one person should bind many people to support family and friends to collect health codes with smart phones, which is convenient for groups who are not used to using smart phones.
