We all know that many museums have implemented a system of free visits. In fact, this is to encourage us to learn more about history or novelty. In many cases, for museums, the data they need may not only be available to the visitors. How much, and also to look at the age distribution of these visitors, coupled with the absence of equipment like museum self-service ticket machines, it has become a very big problem. It is impossible to ask everyone who comes:'What is your year of birth? Picture: Museum self-service ticket machine The emergence of museum self-service ticket machine has solved this problem. Don’t museums implement a free system? Then you need to use an ID card to collect tickets. As long as the ID card is swiped on the self-service ticket machine, the basic information of the visitor can be obtained. We all know that the date of birth can be seen on the ID card. In this way, you can make preliminary statistics on the age distribution of visitors. Of course, as for the division of age groups, this can be set by yourself. Unexpectedly, one thing that is very difficult for people to complete can be completed only by a small function of a museum self-service ticket machine. It is not only convenient and easy, but also very accurate, making the museum's statistics more detailed.
