Hotel card dumped - How to read data blocks

Hello,

Actually I am playing with a Mifare classic hotel card. At this point I was able to fully dump the card, thanks to hardnested command set.
For sector 0 a 1st key was used, remaining sectors do have a 2nd key in use.

Actually I am having to problem to understand the data blocks (no value blocks present), conversation from HEX numbers to ASCII or DEC just shows junk....

What is the correct approach to interpret data blocks? How can I find for example room number, Name .....

Thanks for guiding me in the right direction smile

Re: Hotel card dumped - How to read data blocks

I've run into a couple different things here.

I've seen some that use Mifare Application Directory but most others don't, may be check and see if yours uses MAD?

I haven't had any that specifically are tied to the UID yet.

I have yet to figure out how anything is formatted yet.
