[MIFARE] - Help for MAXI COFFEE DUMP encoding understanding

Hi everybody,

I dumped my badge (Mifare Classic 1k Luxeo) of "Maxi Coffee" machine at 0 euros, virgin, never served, then at 0.30 €, 0.50 €, 0.70 € and at 10 € and I cannot understand the logic from encode in a hexadecimal.

There are keys A and B that ok.

There must be a checksum but I cannot understand it (being a novice it does not help).

I looked at the Mifare documentation but it is not easy to grasp everything when you start.

Here is a part of my dumps:

Can you explain to me / help me understand how to find the value of 0 €, 0.30 € (0x1e), 0.50 € (0x32), 0.70 € (0x46), 10.00 € (0x3e8) in this DUMP?

I would like to be able to put the value I want for example 6.66 € or any other value.

The maxi (I believe) being € 45.99 on this type of coffee badge.

I thank all those who will be able to help me with understanding this encoding.

Good day.

Re: [MIFARE] - Help for MAXI COFFEE DUMP encoding understanding

Hello, you need your key to decrypt your dump 41 5A 54 45 4B 4D in your pm3 there is a tool for decrypted .lua script.

make script list with you pm3,
The hf_mf_dump_luxeo script looks good, check if your key is correct in the script.
Then a help shot to see the commands.

Re: [MIFARE] - Help for MAXI COFFEE DUMP encoding understanding

Good morning,
Thanks for this lead, I'll look that way.

I can find the .lua script on this site or directly in pm3 tool ?

Re, with your pm3 made "script list" you should see the script.

Re: [MIFARE] - Help for MAXI COFFEE DUMP encoding understanding

All I have to do is buy another PM3, mine died and now I have an ACR122U that they lent me in the meantime

Re: [MIFARE] - Help for MAXI COFFEE DUMP encoding understanding

acr122u normally does the job because it's HF, on the other hand I don't really know this stuff and see how to run a script with it, sorry I don't know. Because I think it's with mfoc that he works.
