As the autumn is getting stronger, the sky is also so blue, and the air is filled with a trace of coldness. Autumn is not as hot as summer, and the swimming pool is no longer hot. Facing the summer that is about to say goodbye, grab the little tail left in summer and enjoy a swim in the water. I remember that whenever I go to a swimming pool, I fear two scenes: one is a long queue to buy tickets, the other is swimming like dumplings. Every summer, the swimming pool becomes a holy place for people to escape the summer heat, and men, women and children, all love to play in the water. However, buying tickets has become a big problem for people. Set up a ticket window for unified ticket sales, so that whenever the flow of people is large, there will be a crowded phenomenon of people at the ticket office. Some people are angry because of the hot weather, and the long wait in line is even more exciting. The fire, jump in line, quarrels will inevitably happen, and people will be crowded in line during the hot summer, customers can understand the mood. But in the long run, the image of the swimming pool will be greatly reduced in the eyes of customers. The self-service ticket vending machine can greatly reduce the pressure of ticket sales at the counter. At the same time, when the customer operates the ticket vending machine, they can also feel the good human-computer interaction process, which greatly enhances the customer experience and helps enhance the overall external image of the swimming pool .
