天线设计的基本理论介绍。有利于RFID天线设计。(Introduced the basic theory of antenna design. Conducive to RFID antenna design.)

此代码为RFID中防冲突算法中的固定帧ALOHA算法的仿真(this code for RFID defense algorithm conflict fixed frame ALOHA Simulation Algorithm)

说明：  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.)

rfid二进制防碰撞算法,能运行哦，保证你看后非常满意(this is a very good algorihmn)

说明：  MIFARE DESFire EV1 contactless multi-application IC
