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.)

STM32F1系列属于中低端的32位ARM微控制器，该系列芯片是意法半导体(ST)公司出品，其内核是Cortex-M3。 该系列芯片按片内Flash的大小可分为三大类:小容量(16K和32K)、中容量(64K和128K)、大容量(256K、384K和512K)。 芯片集成定时器，CAN，ADC，SPI，I2C，USB，UART，等多种功能。

某宝商家的工具，原本需要注册，自己破解了免注册，PN532红板+ch340的TTL亲测可完美写uid、cuid卡，可进行key破解，可在配置文件写入已知的key，内附使用说明(NFC pn532 uid cuid)

基于ZigBee协议的协调器创建网络，节点自动加加入，节点通过按钮发送绑定请求，被绑定节点通过按钮应答或者接除绑定，实现ZigBee作为灯具开关，具有很高的应用价值，客服了红外的直线无遮挡传输。-Based on ZigBee protocol coordinator to create the network, the node automatically added to join, the node through the button to send bind requests, the node has been bound by the button or the next addition to answering binding, to achieve ZigBee as a light switch, with a very high value, customer service has Infrared transmission line without shelter.

完美替换rc522，自带LPCD低功耗唤醒检卡，待机功耗大概10uA(Perfectly replace rc522 with LPCD with low power wake-up card. Standby power consumption is about 10uA)
