    I have checked Sample given by TapLinx, but I have same problem.
    I wrote "deepaktiwarideep" in sector 4 block 0, and also wrote the same on sector 4 block 3 (Sector Trailer). But when I authenticate this sector with "deepak" KEY A then it will authenticate it successfully, but when i read sector 4 block 0 then i didn't get "deepaktiwarideep", I only got byte array with single value i.e. "4"(byte[] {4}).

    I am making an Application for MiFare Classic 1K. I need to write data on all sectors, i can write and read data from all blocks easily, but
    When I am writing Block 3 and try to read data by using new key that i have written in block 3 then it is showing blank data. Before writing block 3(before change default facory key) I can read all data but I am getting blank when I change block 3(Default Factory key). Please guide me...
    Thanks in advance
