食堂非接触IC卡的应用设计 内容摘要：在智能卡领域,目前使用较多的就是非接触式IC卡。非接触式IC卡(技术是最近几年发展起来的一项新技术。它是将无线识别技术和IC卡技术集于一体,成功解决了无源(卡中无电源)和非接触这一难题,是电子器件领域的一大突破。随着社会经济和科技的发展,非接触式IC卡技术己广泛地应用于各种行业,特别是公共交通、无线通信、身份识别、金融交易和安全防卫等行业。本文从实际需求出发，结合计算机软硬件的特点，与食堂具体相结合，设计一套食堂非接触IC卡系统。 本文以AT89C51单片机作控制器，建立起以读卡、写卡、控制、等功能的食堂非接触IC系统。本设计的食堂非接触IC卡系统，使用简单、可靠性高、系统维护方便等优点具有着广泛的应用价值。 关键词: 非接触IC 卡电子器件 计算机软硬件 AT89C51单片机 Canteen of non-contact IC card application design Abstract：In the field of smart cards, the use of more non-contact IC card is. Non-contact IC card (technology in recent years developed a new technology. It is a wireless identification technology and IC card technology in one set, successfully resolved a passive (no power supply card) and non-contact with this problem is a major breakthrough in the field of electronic devices. With the development of social economy and technology, non-contact IC card technology has been widely used in various industries, especially public transport, wireless communication, identification, financial transactions and security and defense and other industries. In this paper, starting from the actual demand, combined with computer hardware and software features, combined with specific canteen, canteen design a non-contact IC card system. In this paper, AT89C51 microcontroller as controller, establish the reader, writing cards, control, such as the cafeteria features a non-contact IC system. The design of the cafeteria non-contact IC card system, easy to use, high reliability and easy maintenance system has a wide range of application.
