RFID-Card-Modifier

This repo will help you to modify, clone, read/write RFID card

1. Install Arduino IDE.

2. Build the circuit. Module: RC522, Arduino Uno

        (SDA  => Digital 10)
        (SCK  => Digital 13)
        (MOSI => Digital 11)
        (MISO => Digital 12
        (IRQ  => No need to connect)
        (GND  => GND)
        (RST  => Digital 9)
        (3.3V => 3.3V (must be 3.3V))
   

   Check the "circuit.png" file for details. [Ref: https://randomnerdtutorials.com/security-access-using-mfrc522-rfid-reader-with-arduino/]

3. Download "MFRC522" library for arduino

4. Run the scripts on arduino IDE and modify RFID cards
