According to the proposal, residents in the districts will be given a QR code on their smartphones while those who can’t afford smartphones will receive QR codes through text messages. Additionally, state organizations and companies will issue QR codes for their employees.
A personal QR code contains information about medical declaration, vaccination history, Covid-19 testing result, and health care at home for Covid-19 patients. City dwellers can fill in the medical declaration in the app "Y te HCM" or https://khaibaoyte.tphcm.gov.vn before going out of their houses. They will produce QR codes in checkpoints, factories, supermarkets, convenience stores, and food stores.
