(1) Solve the problem that it is inconvenient for the elderly without mobile phones to go in and out of various occasions without health codes. There must be young people around, so you need to let the young people at home type the health code, or bind the health code to the mobile phone of the accompanying young people, that is, you can't go out alone, even if you buy food, which will bring great inconvenience to the lives of the elderly. If we can achieve integration, we can go it alone.
(2) Updating the printed paper health code in time may need to be updated every day, but once it is integrated with the bus card of the elderly card, it can be updated in time, which is convenient for the elderly. Every old man has a bus card and an elderly card, which ensures the timeliness of information.
(3) One card corresponds to one person, and one old-age card corresponds to one person. You can clearly check whether the card is for your own use through photos. As long as the card is yours, the health code must correspond to you, which saves the step of bringing an ID card in the past, which is really convenient.
The motherland puts itself in the shoes of the elderly and hopes that this move can be realized as soon as possible.
