Mifare card cracked !! (Score 2, Informative)

The announcement of a new stronger card format for Mifare cards didnt come as much of a supprise after they announced that mifare was 'crackable'. However, the demo and explination of how they cracked it is somewhat dubious. What i mean by this is that the cards have several data size formats but each card has a number of data sectors with read write keys. These keys can be the same or they can differ i.e one RW pair for each memory block. Theyve cracked one sector with one RW key, but not all. Thus cloning cards will still be near impossible - yes i know this is relative in computing terms.
