Use MFOC on Mifare with arduino and MFRC522

I have a Mifare RFID Tag and I know the key A.

But I need the Key B.

How can I use MFOC on arduino with MFRC522?

I have been researching but did not find any reference.

Solution

MFOC relies on libnfc. There is a libnfc version out there to make Arduino boards compatible with libnfc.

They have specific software on the Arduino and a patched version of libnfc. They rely on a PN532 reader that is not the same as MFRC522.

There is a similar library for with MFRC522 support but it is not working.

MFOC is also not going to directly run on an arduino.
