This project showcases how to exploit vulnerabilities in NFC cards using Arduino and RFID technology. By leveraging the MFRC522 RFID module, you can read and write data on NFC cards. The code provided offers a foundation for interacting with NFC cards, reading their unique identifiers (UID), and accessing stored data.

This project demonstrates how to exploit vulnerabilities in NFC cards using Arduino and RFID technology. It provides a basic framework for reading and writing NFC cards using the MFRC522 RFID module.

Arduino board (e.g., Arduino Uno, Arduino Nano)

MFRC522 RFID module

NFC cards for testing

Arduino IDE (download and install from (Arduino's official website)

Clone or download the repository.

Open the Arduino IDE.

From the Arduino IDE, navigate to Sketch > Include Library > Manage Libraries.

Search for and install the required libraries:

Open the Arduino sketch file nfc_hacker.ino from the downloaded repository.

Connect your Arduino board to your computer using a USB cable.

Select the appropriate board and port from the Arduino IDE's Tools menu.

Click the Upload button or press Ctrl + U to upload the code to your Arduino board.

Connect the MFRC522 RFID module to your Arduino board according to the provided pin connections in the code.

Upload the code to your Arduino board as explained in the installation steps.

Open the Arduino IDE's Serial Monitor (Ctrl + Shift + M).

Follow the instructions displayed in the Serial Monitor to perform various actions, such as card reading or writing.

Card reading: Read the UID and data from NFC cards.

Card writing (commented out): Enable writing new data to NFC cards. Uncomment the relevant code section to enable writing functionality.

This project is for educational purposes only. Ensure that you comply with local laws and ethical guidelines when using this code.

The compatibility of the code with different RFID modules may vary. Adjust the code according to your specific hardware setup.

Be cautious when performing write operations on real NFC cards, as it may result in permanent changes to the card's data.
