The is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. It is a staple component in embedded systems projects for access control, attendance systems, and security prototypes. However, simulating RFID hardware presents a challenge because Proteus does not include the MFRC522 module in its standard library by default. : Fully close and reopen the software to
: Many Proteus RC522 models require a .HEX file to simulate the actual logic of the RFID chip. This firmware is often provided with the library download and must be linked to the component via its "Edit Component" properties.
