利用微机并行口实现IC卡读写控制的一种方法

本文提出了一种用微机并行口控制IC卡读写操作的方法,给出了微机并行口与IC卡的硬件连接图,并给出了相应的软件控制流程图。该方法比用单片机控制IC卡读写的方法简单,且便于进行数据管理。

This article puts forwards a method about reading and writing operation of IC card which is controlled by microcomputer parallel interface it.Also g ives chart of hardware connection between microcomputer paral-lel interface and IC card,and the corresponding software control flow chart.The method is simpler than that using IC card controlled by SCM,and is easier to data manag ement.
