try searching the web for relavent topics, e.g. arduino rfid will give you plenty of links
test each device RFID reader, LCD, lock control, etc then when you know they all work starting putting the project together
what microcontroller module are you planning to use?

Welcome to the forum

When you read the card how are you storing the code that you read ?

#include <SPI.h>
#include <RFID.h>

RFID lrt720(10, 9);

void setup()
{
Serial.begin(9600);
SPI.begin();
lrt720.init();

}

void loop()
{
if (lrt720.isCard()) {

if (lrt720.readCardSerial()) {

  Serial.println("Kart Bulundu ID : ");
  Serial.print(lrt720.serNum[0]);
  Serial.print(" , ");
  Serial.print(lrt720.serNum[1]);
  Serial.print(" , ");
  Serial.print(lrt720.serNum[2]);
  Serial.print(" , ");
  Serial.print(lrt720.serNum[3]);
  Serial.print(" , ");
  Serial.print(lrt720.serNum[4]);
  Serial.println(" ");
}

}
lrt720.halt();
}

Thank you for posting your code but please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

Hi!

Play a little bit with this examples then join the codes to do what do you want.

Best regards.
