Design And Implementation Of Multi-Meter Application Online Transaction System Based On Java Card

Secure transaction and payment links are transactional e-commerce core supporting technologies. Multi-meter application in public utilities management and the online transaction platform of financial sector, are hot spots of current applaications. Development of multi-meter fare collection system,which takes advantage of E-commerce platform and on-line financial value-added services and gets help from the application support capabilities of Java card,,not only expands e-commerce applications but also is conducives to expanding the financial value-added services to and improving the level of utility management services.Around the function of the system performance to achieve, J2EE framework for multi-layered structure of the system implementation and key technologies of the usages of Java Applet, security and key management, multi-meter implementation of JAVA intelligence card management applications have been studied.which is based on the analysis of self-service applications, transactions, multi-application integration, multi-role support, product distribution electronic information technology, complete processes of business chain as well as the sensitivity and process transaction data such as security In this paper. In accordance with F2C business model, system design includes system topology based on multi-gateway, multi-purpose card based on the JAVA intelligence card, business sub-functions and reversal and dynamic key Management based on session cycle with consideration to three types of transactional e-commerce systems including multi-meter card charges for management system, the financial intermediary business web-based platform and transactional e-commerce.And combined with previously involved in the development " the water management system based on financial intermediary business platform " improvements, structure, processes, functions and security of system are designed and the prototype system of "multi-meter online transaction fee application" is developed, the main functions and processes of which are tested by test data.Aim at characteristics that products/goods flow can be electronic in multi-meter application, Article not only describes the internal logic and data relationships logistics links among the storage of goods after payment transactions, a card written on behalf of delivery, a card written on behalf of unloading,which provides the basis for Reversal of The entire business process.At the same time, this article put Application control information r which includes the amount of goods and purposes, the user and so on togethe to constitute the logistics information.IT completes goods across Application Management System represented by Meter control information, trading platform, measuring devices and forms the integrated logistics process,which reflects the business management function of multi-meter application completely.Furthermore, the actual goods use information feedback channel is expanded and formed from the metering device to the application management system by JAVA smart card as the intermediate medium, which is more conducive to administers for accurate statistical management.
