Topic: mfd Reader/Maker

I might be wrong but so far google hasn't turned up anyway to make the 'mfd' file for mftool.

I tried looking at the example file on http://www.libnfc.org/libnfc/examples/mftool with a hex editor but I couldn't even find where it had the UID in the format?

I'd love a bit more help in understanding the format?

Much Thanks & Respect to Roel for a great API

It is on this page ! Have a look to "Memory Layout", in the 0x00 block : it starts with UID !

You can found more detailed is NXP datasheet: http://www.nxp.com/acrobat_download/oth … rev5_3.pdf

AKAIK, mfd are full dump of a mifare card, when you specify a mfd file for "keys.mfd" parameter; mftool don't care about anything else keys sectors (it just warn about different UID but it seems to doesn't affect the rest of process).

Re: mfd Reader/Maker

ermmm, my apologies, your right, it turns out I made a foolish mistake, I used 7zip on Windows and I needed to decompress the file again as is the case with some formats. Little did I know that I was opening the wrong file in the hex editor, I can see all the data clear as day.

Thanks rconty!

I will try to update this page this week, the information is a little bit "compact" right now about this tool wink
