  本示例使用的发卡器：EM4305 EM4469 ISO11784/85协议125K低频FXD-B动物标签读写发卡器-淘宝网 (taobao.com)

        EM4305/EM4205卡是采用瑞士EM微电子公司工作频率为125kHz，具有读、写功能的非接触式RFID射频芯片，它具有功耗低、可提供多种数据传输速率和数据编码方法等特点，适合射频芯片ISO 11784/11785规范，该芯片被广泛应用于动物识别和跟踪、智能门锁、通道门禁等一卡通管理系统。

       EM4305/EM4205卡的EEPROM储存空间为512位，分为16个块，每个块32位，块1为UID块，块2为密码块，块4为配置块，块14、15为锁定标志块。可在-40℃~85℃在温度下工作。

       EM4305/EM4205卡可以修改其配置信息将其模拟成兼容EM4100的ID卡，可用于ID卡的复制。
