Introduction The RC522 is arguably the most popular RFID/NFC module for hobbyists and embedded engineers. Based on the Philips MFRC522 chip, it operates at 13.56 MHz and allows you to read and write data to tags like Mifare Classic 1K and 4K. When building complex systems—like access control panels, inventory trackers, or smart payment simulators—testing code directly on hardware can be tedious and expensive. This is where Proteus Design Suite and the RC522 Proteus Library become essential. #include &lt;SPI

Use the Terminal Mode in Proteus to add a POWER terminal of 3.3V. Do not tie VCC to 5V. Even in simulation, some models enforce voltage limits and will “fail” (output undefined logic levels) if overvolted. Writing the Arduino Sketch You will use the standard MFRC522 library in your actual Arduino IDE. Here is a minimal sketch to simulate reading a tag UID:

Serial.println(); mfrc522.PICC_HaltA();

Proteus is known for its unique ability to simulate microcontroller code (specifically Arduino HEX files) alongside electronic components. However, out of the box, Proteus does not include a native RC522 model. Enter the third-party RC522 Proteus Library: a custom simulation model that bridges the gap, allowing you to simulate your entire RFID project before soldering a single component.
