IC Card Reader In Smart Network Computer System

In the recent years, Network Computer appears as a kind of newly rising terminal mode. Compared with traditional PC, it is applied in more and more fields because of its low costs, easy maintenance and security. In the Network Computer system, Network Security must be taken into serious consideration. Therefore, Network Computer system utilizes Smart IC card to conduct identification and access control. By so doing, the IC card reader becomes an indispensable part of Network Computer security system.This paper aims to put forward a complete design of Smart IC card reader based on Serial Port and propose the way of realizing it for the purpose of Network Security. SMD is adopted to make Smart IC reader smaller in this design. To reduce the volume of Smart IC reader, Serial Port powered technology is employed to get power from the signal line of Serial Port. For this reason, low-power consumption components are adopted in the design and some traditional designs are simplified to reduce the power consumption.MCU program of the IC card reader, the driver of Linux and Windows Operating System base on CT-API are discussed too in this design. The whole software program of IC card reader gives prominence to transparent transmission of data, and simultaneously takes the characteristics of the MCU software into account. The MCU program stresses the reliability and perfection of the product whereas the design of drivers mainly takes account of the delaminating structure of software in accordance with industry's current standard.
