In this era of rapid economic development, people's living standards are constantly improving. Correspondingly, the flow of passengers across the country is also increasing, and cars and trains have become one of the main means of transportation. The stations in major cities are constantly being renovated and expanded to welcome more passengers. With more passengers, buying and collecting tickets becomes troublesome. Author I used to spend winter and summer vacations, when I went to the train station to collect tickets, when I entered the ticket office, I saw a large group of people queuing to buy and collect tickets, and I had a headache. It took more than half an hour to get tickets each time. When it comes to tickets, what’s more serious is that many people are in a hurry. Seeing that the time for the train is getting closer and closer, they are still queuing to pick up the tickets. Sometimes just because of the interval of a few minutes, they miss the train. People collapse. The self-service ticket machine came into being under such circumstances. A machine that does not require any language to communicate. Passengers who have bought tickets online, as long as they take out their second-generation ID cards and scan them in designated places. It is spit out from the ticket outlet. The whole process will not take more than 15 seconds. The operation is simple and time-saving. It is definitely faster to pick up one person after another than manual ticket collection. Even if it is in a hurry, it will definitely be very fast. Get the ticket quickly; the self-service ticket machine reduces the work pressure for the staff.
