Nowadays, people have higher and higher requirements for the intelligence and automation of machinery. In line with this, self-service equipment technology is also developing at a high speed, and the scope of use is becoming wider and wider. Now many places use self-service payment machines instead of manual payment. Picture: Before the self-service payment machine, people had to pay phone bills, utility bills, etc., all needed to be processed in the business hall. If there were a lot of people, they would have to wait in line. Not only a waste of time, but also not very convenient to handle. Now it is much easier to pay fees with the self-service payment machine. People do not need to go to the business hall to let their staff handle it, and they can use it to do the payment. It uses a full touch screen, which is convenient for users to operate; in addition, it also has functions such as finding change and printing bills for users; it has a stylish and generous appearance, is small in size, and does not occupy too much space. Compared with manual operations, The price/performance ratio is very high. The use of self-service payment machines to replace manual payment is very successful. It does the same work as manuals, but the effect is much better than that of workers, and it has won public praise.
