Laravel 我的rfid设备如何在我的电子停车项目中读取和切断同一设备的平衡？

我的设备是rfid卡Mifare类型、NodeMCU ESP8266 v3和rfid RC522模块。我的基于网络的RFID项目有问题。我将Laravel7用于web和MySQL

所以我和拉威尔有一个电子停车项目。rfid阅读器工作正常，数据显示如下图所示

所以我有一列，名字是balance。所以当我把车停在停车场，当我扫描我的rfid卡时，余额会被扣除。可以在同一个rfid设备上实现吗？它就像我的rfid设备有2种模式，读取模式和剪切平衡模式。这是我的带有arduino IDE的rfid脚本

无效设置（）

void循环（）

void循环（）{
//将主代码放在这里，以便重复运行
readsuccess=getid（）；
if（readsuccess）{
数字写入（板上发光二极管，低电平）；
无线客户端；

字符串UIDresultSend，postData；

所以请有人能帮我吗？多谢各位
