Arduino RFID reading delay

Hi, i need help how can i add reading delay in this code i just copy it online and it's working but the problem is everytime i tap my rfid cards it prints continuously.

#include "rdm630.h"

rdm630 rfid(6, 0); //TX-pin of RDM630 connected to Arduino pin 6

void setup()
{
Serial.begin(9600); // start serial to PC
rfid.begin();
}

void loop()
{
byte data[6];
byte length;

if(rfid.available()){
//concatenate the bytes in the data array to one long which can be
//rendered as a decimal number
unsigned long result =
((unsigned long int)data[1]<<24) +
((unsigned long int)data[2]<<16) +
((unsigned long int)data[3]<<8) +
data[4];
Serial.println(result);
}
}

You can, but most certainly should NOT, add a delay() statement anywhere you like.

Normally, we like our computers to be a fast as possible, and abhor programs that deliberately take a long time. Why do you want to slow anything down?

I tried adding delay in some places of my code it works but it slows down the reading and it also repeats the reading.

but it slows down the reading

Exactly. Why would you want to do that?

and it also repeats the reading.

You need to post your current code. The stuff you posted earlier was useless.
