In other words, if citizens don't carry smart phones, people around them can use their health treasures to help check their health.

The "health code" in various places basically has the function of "collar", which is convenient for the elderly, children and other users without smart phones to travel. For example, Chongqing "Yukang Code" provides the function of "declaration on behalf of the elderly", and children of the elderly, guardians of children and other relevant personnel with smart phones can collect "Yukang Code" for them to show when the elderly and children travel.
In Heilongjiang, the elderly and children can apply for "Longjiang Health Code" through relatives or communities. When traveling, they can take one of three ways: printing "health code", reporting dynamic verification code or reporting their ID number. After being verified by the collector and entered into the system, it can pass smoothly.
