ioProx Raw to (FC)(VN):CN

Folks, does someone know or can explain how to convert and ioProx Raw format back to the facility code… format?

Raw: 00784b60365d4753

Thank you

Do you also have it in the XSF(xx)xx:xx format? That’s a bit easier to work with, unless you need the raw specifically

Hi, that is the basis of my question. If I do not have that info, how can I go from raw.

Using the format from this thread to start:
https://www.proxmark.io/www.proxmark.org/forum/viewtopic.php%3Fid=364.html

Your data would probably be FC: 2D and CN: 25939, assuming that’s the correct format

It does check out for my one test card, but that’s not too much to go on

And I guess the VN is just probably 01? It’s probably easy-ish to brute that part at least…

Edit:
When I emulate that data with a F0 my PM3 reads different raw… Let me see if I can figure out the discrepancy…

Also, just out of curiosity, what did you use to get the raw?

Alright, I think I’ve got it this time:

Your card seems to be FC: 2D and CN: 26024 and VN: 01

That gives the correct raw
