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:
Unlike the older version, the new library includes an parameter. Set it from 0 (no read) to 100 mm (max range). This allows you to simulate how tag orientation affects read success—perfect for security access simulations.
The updated RC522 Proteus library enables the simulation of the within the Proteus Design Suite, allowing developers to test RFID-based security and access control systems without physical hardware. This update often includes improved simulation models that more accurately mimic the behavior of real-world RFID tags and reader modules.

From a commercial perspective, Labcenter focuses on components that are deterministic and widely used in industrial prototyping. RFID simulation is complex, computationally intensive, and would require integration with external scripting or a full electromagnetic solver — not Proteus’s core strength. Additionally, the RC522’s register-level behavior is specific to NXP’s MFRC522 chip. An accurate model would require licensing or reverse-engineering, which is legally and technically impractical. Therefore, users will likely never see an “official” updated RC522 library. Set it from 0 (no read) to 100 mm (max range)

If you see gibberish text or nothing at all in your Proteus Virtual Terminal window, right-click the terminal component during design mode. Verify that its operating baud rate matches the value declared in your code (e.g., 9600 ).
