So far, the car has become an indispensable means of transportation in people's lives. It is convenient, fast, and affordable. In many cases, people are willing to choose it. Nowadays, Internet technology and information are well developed. Online ticket purchases, online shopping, etc., which could not be achieved before, can now be achieved. As one of the convenient means of transportation, cars are extremely popular. While being popular, there are also minor problems. Bus tickets at the passenger station are tight, it is difficult to buy and collect tickets, and the ticket halls are extremely crowded. According to this kind of situation, the self-service ticket machine can easily solve it. For example, when encountering national holidays, many people choose to buy tickets online, but it is quite crowded and difficult to pick up tickets at the station. However, it is much easier and faster to pick up tickets through the self-service ticketing machine. The ticket can be obtained on behalf of the ID card, which saves the communication with the staff and avoids language barriers. The author once went to the bus station and saw a large row of self-service ticket machines. Passengers pick up their tickets at the self-service ticket machines much faster than manual ticket sales.
