Das funktioniert soweit auch alles, aber wenn ich meine Karte an das Modul halte, kommt folgender Fehler:
Code: Alles auswählen
Card detected
Card read UID: 136,4,150,165
Size: 4
AUTH ERROR!!
AUTH ERROR(status2reg & 0x08) != 0
Authentication error
# This is the default key for authentication
key = [0xFF,0xFF,0xFF,0xFF,0xFF,0xFF]
Welche Möglichkeiten habe ich diesen Authentication-Key von einer Karte auszulesen?
Hier auf dieser Seite ist der Aufbau beschrieben, ich werde daraus aber nicht schlau...

Hier der Code der Read.py
Vielen Dank für die Hilfe!
