However, before we start, it's essential to set the right expectation. Many users have confirmed that RC522 cannot be fully simulated in Proteus. The Proteus library, if it exists, often provides only a for your circuit design without a complete simulation model (like a .DLL ) driving its behavior.

⚠️ : The RC522 is a 3.3V device . Do not connect its VCC pin to the Arduino's 5V output, as this could damage the module. Connect it to the Arduino's 3.3V pin or a separate 3.3V regulator. Also, while the MFRC522’s I/O pins are 5V tolerant, it is recommended to use a level shifter or, at a minimum, series resistors on the SPI lines for protection in a real project.
