Multi-application Smart Card Payment Transaction System Design And Implementation,

Smart card is an inlaid with SCM chips card. The smart card contains CPU, rich hardware resources and chip operating system. So, it has become an important and security equipment especially in commerce. Nowadays, with the e-financial and e-rapid development, smart card as credentials, electronic purse, and electronic passbook and various certificates and important data carrier play increasingly important role.Smart card security is moving, high-speed, convenient direction rapidly. As a multi-purpose card and the user download the increasing demand, the existing smart card and chip operating system on a number of security flaws exposed. They provide the user download or not, that is fixed for all users of the operating system; or allow users to download software, but just trying to realize its procedures to protect user's data.To overcome the existing smart card and the chip operating system security flaws, the author research and proposed a new practical and smart card system architecture, and design a complete multi-application smart card file structure and the corresponding high-security key system and security mechanism. And in order to test them to design a smart card issuing system, end-use process, the final design of the smart card transactions core system, experiments show that the whole smart card system.To deal with a multi-application smart cards in electronic payment application, this text discuss the security of smart card-based micro-payment system design and implementation. Through this system, the user could select the appropriate function through the POS terminal, and finally completes the payment transactions. The program is a little complicates to achieve, but safer, faster, more fit to the existing the domestic financial Network Status, succeed raised the range of electronic payment.
