This news is great news for those of us who often take the train. Before this, the self-service ticket collection machine was only installed in the train station, which affected the convenience of passengers. It’s different now. You can buy tickets on this self-service terminal, or you can take your ID card and pick up the tickets at the self-service terminal after buying tickets online. The installation of the self-service ticket vending machine is convenient for you, me, and him. We don't have to go to the station to collect tickets when we are busy. The use of this equipment is an important process of scientific and technological life.
