无线射频识别技术(RFID)是自动识别技术的一种高级形式。随着信息化技术的不断发展，无线射频识别技术(RFID)的应用也越来越广泛。本书主要介绍了无线射频识别技术的基本工作原理和具体应用，并列举了大量的应用实例，如动物识别管理、配送中心管理、矿井管理、停车场管理、军事物流运用等-Radio frequency identification technology (RFID) is the automatic identification of an advanced form of technology. As information technology continues to develop, radio frequency identification technology (RFID) applications are increasingly widespread. This book introduces the radio frequency identification technology, the basic working principles and specific applications, and listed a large number of application examples, such as animal identification management, distribution center management, mine management, car park management, the use of military logistics

为了系统的安全性，为门禁控制系统增加了登录功能，通过从后端数据库录入管理员信息，包括用户名与密码，便可在用户界面使用数据库中的信息进行登录，极大的保证了系统的安全性。用户可以通过数据库匹配方法来对ID卡进行登记、删除等操作。(In order to ensure the security of the system, the login function is added to the access control system. By inputting administrator information from the back-end database, including user name and password, the information in the database can be logged on in the user interface, which greatly guarantees the security of the system. Users can register and delete ID cards through database matching method.)
