As a professional electronics engineer, I must warn you:
Test microcontroller code (often written in C or Arduino) interacting with the RC522 before physical assembly. Rc522 Proteus Library
| | Impact | | :--- | :--- | | No antenna matching simulation | You cannot test if your PCB layout affects read range. | | Ideal power supply | The library won't simulate brown-out conditions or voltage drop during RF transmission. | | No noise or interference | Real-world RFID fails due to EMI from motors, Wi-Fi, or other readers. Simulation won't catch this. | | Probabilistic behavior | Real cards sometimes fail to respond; simulation is deterministic (always works or always fails). | | Limited card emulation | Simulating multiple cards in the field or card movement is rare in free libraries. | As a professional electronics engineer, I must warn
