Financial innovation is to obtain higher profits and to expand the range of financial business in the financial sector, innovating financial business and financial technology. Based on the requirements of financial innovation, this paper designed and implemented a system of financial payment business.This paper first describes the background and significance of this project; then detailed introduces the technology used in the system implementation phase; then based on analysis of the functional requirements of the system, puts forward the design of financial payment business system, in which the server includes the applications warehouse subsystem and management system, and the client includes framework program and business applications; then detailed analyzes each part and module in the implementation of system, and provides a brief description of exception handling; finally, is the comprehensive experiment, including unit test, integration test, functional test and performance test.Applications warehouse subsystem is developed based on Node.js, in order to compensate for the shortcomings of single-threaded, using cyclic service queue to achieve a multi-process mechanism. Management system is based on the MVC mode of Servlet/JSP, implementing simple management for applications warehouse subsystem. Framework program provides the business applications operating environment. According to current requirement, this paper developed POS business and NCMS purchase medicines based on jQuery Mobile.The main function of the applications warehouse subsystem implementation are:applications list download, icon to download, application files to download, client framework program download, medicines list download and turnover management; and main functions of management system are to upload files, view services and start services. POS business application implemented consumption, balance inquiries and other functions; and NCMS purchase medicines business application achieved business process of procuring medicines.After testing, each function of the system achieves the desired effect and meets the design requirements, and can be operated normally and steadily. Finally, the work is summarized and future work is proposed.
