With the advent of the new era and the rapid development of the service industry, a self-contained terminal control business with its high-performance operation provides reliable information, saves a lot of manpower and time resources, and maintains flexibility, thus becoming an insignificant and important part of the financial services industry. This article aims to study the financial self-service transaction method based on a wireless communication network. This article starts from three stages such as functional planning, future direction, and final management and makes every effort to help the bank focus on three-dimensional and intelligent development of main business channel services from three levels such as technology, facilities, and channels, so as to realize the banking business from “production and direction” to “the transformation of marketing and experience,” providing end users with a brand-new work experience at anytime and anywhere to increase productivity and reduce labor costs. The research results show that more than 80% of the interviewed people have expressed affirmation of the financial self-service transaction service under the wireless communication network, and the interactive design of the operation interface and the information data and security system need to be further improved.
