As shown in the previous tutorial, using the MFRC522-python library (https://github.com/mxgxw/MFRC522-python.git) and the data read example script, I’m able to read the UniqueID (UID) of my NFC card.
On GPIO17 (= pin 11) I have the 220v relay signal that open the electric door lock. Therefore, editing the read example script, if an allowed UID is read than the door will be opened!
I add also a log file to control if somebody try to force the system
