摘要
在现有的智能卡系统中智能卡处于被动的地位,只能在专有设备的场合使用,从而限制了智能卡的应用。该文在分析现有智能卡应用系统的基础上,基于蓝牙技术,给出了一种新概念的蓝牙智能卡应用系统。该系统中交易双方处于平等地位,能够实现双向的数据流动,联网和使用方便。同时给出了相应的应用模式和交易流程。实验室的原型系统表明这种方案是可行的。
Smart cards play a passive role in existing smart cards system. Furthermore, smart cards should be used with compulsory devices. This will eventually limit its potential. After analyzing the existing smart cards system, a novel smart cards system based on Bluetooth is proposed. The proposed system has many merits： both sides play an active, equal role in the new system; it lets mutual data transmission between users; it is convenient to use it and it is also very easy to be connected through network. Application modes, transaction flows such as on-line and off-line flow are also introduced. The system prototype based on Bluetooth in laboratory shows reasonable results and demonstrates the feasibility of the new system.
