The Research Of GPRS-based Mobile Payment System For Wireless POS

Wireless mobile POS payment system is focused on electricity demand side management, set mobile communication technology, wireless POS technology, data interface technology, and the electricity tariff in advance of the integrated payment integrated payment systems. Its main function is to manage the payment terminal, user fees, user information query and set system parameters, increasing user fees channels, to achieve tariff management, information technology, real-time and increase the electricity power enterprise management level and efficiency, Meet the needs of modern management, marketing and enhance the market competitiveness of power enterprises. Payment system by the system master station, the mobile payment terminal and the main station and the communication channel between the terminal component. System Master is the mobile payment system operation and management of the command center, whose main tasks include communication management, system control and information management. Where communication is a contact system master and the link between Terminal POS machines, electric toll collection system plays an important role in the whole.This subject comes from Shandong Electric Power Technology Co., Ltd. Cooperation Division power bill payments, firstly, with the composition, the system communication features, requirements, and wiring construction, and so some of the considerations on the system used by the communication channel for a detailed analysis and comparison, combined with wireless network communication technology, mature application and rapid development, decision GPRS radio channel used as a connection based on the main station and the terminal of the bridge. GPRS Based on the analysis of the structure and function, positive affirmation of the GPRS wireless communication technology in electric power marketing system is feasible.This paper studies the GPRS wireless network transmission system implementation issues, which analyzes the GPRS wireless communication network in the payment system program. Program uses the GPRS network and virtual private network technology (VPN) combined communication and networking options to meet the requirements of POS machines as payment terminals, which integrate GPRS POS machines and embedded wireless module TCP/IP protocol stack, Between the power company and the wireless network using the data bandwidth of 2M line connection. This article is also on the network transport layer data transfer protocol choice, port mapping, GPRS network security issues related to research, which also proposed to improve the payment system, some security options. Furthermore, this article introduces the POS machine and POS machine hardware specifications of the function, and then combined with the system master station hardware and software architecture schematic diagram detailing the main stations of the system and its functions and terminal POS machines, system security requirements and Protection of system security measures taken. Finally, the paper describes the design of software system architecture and logic function of each part of the description, the terminal POS machine application development environment, development of language and functional operation of the process, WEB client development environment and development language, and the detailed application design.
