Arduino RFID Cloner

This project allows you to clone RFID tags and cards operating at a frequency of 13.56 MHz.

^{Note: The OLED display functions correctly in reality; any display issues in the image are due to the camera.}

TODO

• ❌ Add 125 kHz read/emulate support
• ❌ Make better interface
• ❌ Design pcb

Libraries

To ensure proper functioning of the code, you need to install the following libraries:

• MFRC522.h
• Wire.h
• Adafruit_GFX.h
• Adafruit_SSD1306.h

How to Copy Data:

To duplicate data from one card to another, follow these steps:

1. Begin by reading the card from which you want to copy data.
2. Flip the switch connected to A0.
3. Now, place the second card.

Required Components:

• 1 Arduino (preferably Nano)
• 1 MFRC522
• 3 LEDs
• 5 resistors 3x 330 Ω (for LEDs), 2x 10000 Ω (for switches)
• 2 switches
• 1 OLED display ssd136
• 13.56MHz RFID cards/keychains with write capability
• Power source

Please make sure to wire the components as specified in the project documentation for proper functionality.
