Connecting my MFRC522 RFID to WEMOS D1 R2

I'm trying to connect a mfrc 522 rfid to my wemos d1 r2 but when i run the example firmware_check from mfrc library, it said that it's a defect or unknown firmware. Any ideas about this one?
i've been looking around for another libraries but found no salvation

The message appears to refer to the RFID card/chip and not the Wemos ESP8266.
Look at the readme here GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522 to see if your RFID is supported and other troubleshooting tips.
