Convenient self-service terminals are the trend of urban life development. China's cities are densely populated, higher than foreign cities, and some financial payment behaviors such as water, electricity, gas, mobile, transportation, bus card recharge, transfer payments, etc., must be paid to various units. Some use bank or postal savings as a payment window. However, problems such as limited business hours, heavy workloads, and large number of contributions have made it difficult for the public to pay fees. The emergence of convenience self-service terminals has solved the problem of public payment.

        Self-service terminals can include public utility fee payment, mobile phone recharge payment, movie ticket purchase, welfare lottery purchase, performance ticket purchase, train ticket purchase, coupon printing, insurance purchase payment, bank card transfer, credit card repayment, bank card balance Query, group purchase, mall and other convenience payment functions. The self-service terminal has a beautiful and simple appearance, and the all-weather self-service and simple touch operation greatly facilitates the daily payment and electronic payment services of the consumers.
