For more advanced simulations, you might need to use other library components, check this RF module installation guide for general library management. If you'd like, I can:

if it was already open to refresh the component database. 3. Interfacing with Arduino in Proteus

Take the downloaded .LIB and .IDX files and copy them into the LIBRARY folder. If your package also contains a .HEX file (the RFID firmware model), do place it in the Proteus system folder; instead, keep it in a dedicated project folder that you will reference later.

However, not every physical component has a corresponding simulation model in the standard Proteus library. This is especially true for the RC522: many users have noted that “Proteus does not come with an RC522 module pre‑installed” and that “RFID cannot be simulated in Proteus” – meaning no ready‑made model exists. The only way to simulate an RC522 is to find a third‑party library that includes the necessary .lib (component symbol) and, often, a .hex file that emulates the RFID reader’s behaviour.

: download a trustworthy RC522 library, install it in Proteus, and experience the convenience of testing your RFID code in a virtual environment. The only limit is your imagination.

Semiconductor companies often provide Proteus-compatible models for their chips in the "Design Resources" section of their official websites.

For most developers, the Virtual Terminal method is the best balance between effort and results. It allows you to rapidly prototype the authorization workflow without being blocked by the absence of a native RFID tag model in Proteus.
