One way is that children can teach the elderly to use smart phones, because the media network is very developed now, and smart phones have replaced many things, such as cash and watches. Children can teach the elderly to use smart phones, which will make it much more convenient to go in and out of some public places. Moreover, after the elderly can use smart phones, they can watch news and make video calls to their children. In today's society, smart phones are very useful in our lives and are currently in fashion. Everyone must use a health code when entering or leaving public places, and the staff will not let them enter public places, including buses, because they don't have smart phones. Because there is more than one passenger on the bus, the bus driver is responsible for all the passengers. Therefore, for the safety of passengers in the bus, the health code must be used when taking the bus, so the elderly who can't use smart phones will be hindered. In this case, children can teach the elderly to use smart phones.
If these elderly people really don't want to learn to use smart phones, there is another way to solve this problem, that is, they can apply for paper health codes in the community or village Committee. This is convenient for the elderly who can't use smart phones, because this paper health code can be easily carried under any circumstances, and then go to the community or village Committee for regular physical examination, change the health code and update it in real time.
Due to the epidemic situation, people need to use health codes when entering and leaving public places. However, some elderly people are hindered from using smart phones to enter and leave public places, and they often have conflicts with staff. The above two methods can solve the problem that the elderly who can't use smart phones use health codes.
