The so-called self-service ticket vending machine is understood literally. For example, when we travel, we need to take out the relevant ticket collection voucher in front of the ticket vending machine to pick up the ticket by ourselves. This measure is quite convenient and quick. Author I have had such an experience once. Once I had to go out to a far door because I booked tickets online, so I went straight to the train station after getting off work. When I arrived at the scene, I saw so many people piled up in front of the window. It was about to break, and finally found out where there was a self-service ticket collection, and hurried over. Seeing that the driving time is getting closer and closer, I am very anxious, and there are many ticket collection teams there. I thought that this trip was over, but the subsequent development was unexpected because the ticket collection speed was fast, and the ticket was changed in about 10 seconds. One person, the ticket collection process is very simple, click on the Internet to collect the ticket, and then directly scan the second-generation ID card at the designated place, and the ticket will be printed out from the ticket outlet. This saves a lot of time for people in a hurry. I have hope again! Look! It’s beautiful and convenient to change. Before, it took a lot of time to get tickets at the manual counter, because in the queue, there were people who bought the tickets, and buying tickets was more cumbersome than getting tickets. People who are tight may not be able to get a ticket to catch up with the car. It is wise to use self-service ticket vending machines at stations to separate ticket sales and ticket collection, which reduces the workload for staff and saves passengers' time.
