How can I apply for a student health code without a mobile phone?

People who don't have mobile phones or smart phones, such as the elderly, can take the initiative to contact the community (village) staff to apply for a health code or issue a health pass, which is convenient for them to enter and leave the community (village), shopping malls, supermarkets, financial outlets, medical and health institutions and other public transport means such as airplanes, trains (high-speed trains), subways, buses, taxis (online car rides).
