With the increasing use of self-service equipment in people's lives, the functions have been continuously improved. Gradually, many self-service equipment can be used independently, without the need for working personnel to operate. Just like the application of a ticket vending machine in a theater is a good interpretation of its function. Picture: Self-service ticket vending machines are now going to the big theaters to watch movies. Very few ticket sales are done manually. Most of them use self-service ticket vending machines to sell tickets to people. Since the introduction of self-service ticket vending machines, the waiting time for purchasing movie tickets has been shortened, which also saves people the time in queuing. Not only does it bring better services to people who watch movies, but it also benefits the theater itself, because reducing the use of manpower is equivalent to reducing theater costs, and theaters can use this part of the funds to make other investments. Self-service products have gradually entered the entire market. Self-service ticket vending machines are just one of them. Their use plays a huge role in people's lives and the development of enterprises.
