Hello guys,
thank you first of all ..
I hope someone can help me ..
I have a 1K Mifare classic
with keys A and B of the two protected sectors 01 and 02.
This card stores an integer without a comma.
After several attempts I managed to understand that UID is involved in the calculation.
in fact same DUMP but different uid generates an error in the reader.
DAta for two cards:
the key A|B sect 01:
060504030201|280492231195
the key A|B sect 02:
043028239295 | 280492231195
see todheter the details of Cards: CARD N°1:
