As far as the paper was concerned, I came to the conclusion that it's not 
possible to clone the cards.  I don't have the paper here with me but I 
think they mention that at the end that based on the information they 
provide cloning cards is not feasible.  In fact, they can't read all the 
data, and there are some pretty strong 'ifs' to reading any data (except 
first sector), which is knowing one byte on that sector.  Did anyone read 
the paper or have any other references that state/prove that cloning is 
possible?
