Hotel 1 k Classic

Hello Again,

After fixing my proxmark in the previous thread, I have now a question about how to properly analyse data on the card.
I am in an hotel which use mifare classic 1k for the elevator as for the room (same card for both)

I was wondering on how they store the data on the card.
If I sniff the card in between the elevator on the card and in between the room and the card will I be able to see where they store the data on the card ?


Thanks

Re: Hotel 1 k Classic

some hotels / elevators allow the access based on the card Unique ID mapped back to their database,  ( and some even use rolling-window to change your UID everytime you swiped to prevent the use of a cloned-card )
so there can be cases that no data meaningful at all stored on the card, thus save people the trouble editing the data in it
