Authentication problem MFRC522 Pi4j

Tue May 14, 2019 9:15 am

I'm new to Raspberry and I try to read data from RFID reader RC522, but I have some authentication problems. I'm using LyangYuen's project ( and I have a RPi 3B+. I have the same authentication issue with Python.

Can someone help me ? I've seen diozero lib but I don't understand how to make it work.
