No official, updated, or native Proteus library exists for the MFRC522 (RC522) RFID module. The component is not included in the standard Proteus libraries (ISIS/Ares). Existing community-made libraries are outdated, often unstable, and incompatible with modern Proteus versions (8.x and above). For accurate simulation, users must rely on custom DLL creation, Arduino co-simulation, or hardware prototyping.
Previous versions (often from 2013-2018) had major flaws: they didn’t support the full MIFARE command set, crashed on PCD_AUTHENT, or failed to simulate multi-block reads. The updated library introduces:

Restart: Always restart Proteus after adding new components so the "Pick Device" list updates. Step 2: Circuit Interfacing (The Wiring)
File Corruption: If the component appears in the list but won't place on the schematic, the .LIB file may be corrupted or from an incompatible version of Proteus. Report: RC522 Proteus Library – Updated Status &
For electronics hobbyists, embedded system developers, and engineering students, Proteus Virtual System Modeling (VSM) is a game-changer. It allows you to simulate microcontroller circuits without physical hardware. Among the most sought-after components for simulation is the RC522 RFID Module—a popular, low-cost device used for contactless communication (13.56 MHz) with tags and cards.
If you’re still using the old RFID-RC522 library from 2017, you are losing valuable development time. Here is a feature comparison: embedded system developers
The RC522 is a cheap, ubiquitous RFID/NFC reader operating at 13.56 MHz. It interfaces with microcontrollers (Arduino, PIC, 8051, STM32) via SPI. Before the updated library, simulating this meant either:
