When we use MFDataArea.read method to read a data block.
We specify a MFKey as a parameter to authenticate a Mifare card.

If the Mifare card' key which we read, is 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF or 0xA0 0xA1 0xA2 0xA3 0xA4 0xA5.
That is not our specifying key.

It should, but It do not throws a MFStandardException.

How can we make it to throw the exception, when we read a FF key's Mifare card?
