实时在线云消费机、考勤门禁控制板、网络读卡器Java Socket源代码

本文主要是介绍实时在线云消费机、考勤门禁控制板、网络读卡器Java Socket源代码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

消费机UDP通讯协议介绍：

云消费机通讯协议附Java、PHP、Python、C# 、.Net、VB、Delphi、VFP、Android示例源码_zhangjin7422的专栏-CSDN博客设备向服务器发送的指令格式，每个字段用半角逗号(,)分隔。序号指令名称指令格式指令说明示例1响应服务器的搜索100,包序列号,终端IP,子网掩码,网关IP,远程电脑主机IP,端口号,终端硬件号响应电脑发出的搜寻局域网内所有终端设备指令000,就是电脑软件用广播式向39190端口发送字符串“000”100,00009,192.168.1.218,255.255.255.0,192.168.1.1,192.168.1.3,39169,1https://blog.csdn.net/zhangjin7422/article/details/118608559

消费机介绍：

账户金额等所有持卡人信息存在电脑服务器上，在线刷卡消费时设备将IC卡的物理卡号和消费金额传到服务器，服务器脑处理保存后将消费结果返发到消费机上显示，内置高灵敏扫码模组，扫码信息即时上传到服务器，脱网时支持白名单记账消费。https://item.taobao.com/item.htm?spm=a1z10.1-c.w4004-21914722028.2.60cc6baaxEPiPw&id=17021194999https://item.taobao.com/item.htm?spm=a1z10.1-c.w4004-21914722028.2.60cc6baaxEPiPw&id=17021194999

实时门禁控制板：

考勤门禁控制板可外接刷卡读头、扫描枪、人脸识别器，将读取到的ID号即时发送到服务器，由服务器的软件判断后再返回开门信号或反馈信息。脱网时由控制板内的白名单控制刷卡是否可通行。
