[求助] 求大神指点迷津

我想做一个刷卡充电  的程序
刷一次卡 3小时刷3次卡是9小时  然后这个刷卡次数可以循环这个时间时根据刷卡的次数去倒计时

现在是刷一次卡就开始计时了刷第二次已经没有反应了怎么解决求指点

#include <SPI.h>
#include <RFID.h>
RFID rfid(10, 5); //D10--读卡器MOSI引脚、D5--读卡器RST引脚
String N = ""; //字符串转整型用的变量
long Frequency = 800;//频率
unsigned char* ID = rfid.serNum;//无符号字符型指针
unsigned long Record; //用于记录开始时间
unsigned long Now; //当前时间
unsigned long deleyTime = "";//3小时

int addNum = 0; //写入读卡次数
int redNum = 0; //读取读卡次数
int Buzzer = 5;//蜂鸣器针脚
int Green = 3;  //正常启动指示灯
int Blue = 2; //读卡指示灯
int Red1 = A2; //读卡一次
int Red2 = A1; //读卡二次
int Red3 = A0; //读卡三次
int Relay = 3;  //继电器

void setup()
{
  Serial.begin(9600);
  SPI.begin();
  rfid.init();
  pinMode(Buzzer, OUTPUT);
  pinMode(Green,OUTPUT);

  pinMode(Red3, OUTPUT);
  pinMode(Relay, OUTPUT);
  digitalWrite(Green,HIGH);
}

void loop()
{
  //找卡
  rfid.isCard();
  //读取卡序列号
  if (rfid.readCardSerial())
  {
Serial.print("The card's number is  : ");
