How do I go about cloning this card? Image inside

Hello, ive gotten my proxymark running perfectly now its time to start cloning.

I watched amals tutorial on cloning cards and (correct me if I’m wrong) but it looks like he chooses the brand of the card in order to get the formatting correct?

For example, he used the Gallagher prompt to format his Gallagher card, makes sense?

Here is a scan of the fob I’m looking to clone.
The card is labeled with an XSF(01)f2

Under what setting is used to clone this card type?

Thanks from a total noob

You’re looking for the lf io commands, if you have a blank T5577 chip to copy to, you can copy this particular chip with:

lf io clone --vn 1 --fc 242 --cn 38944

Thanks for that. Where in that command strip do I insert the raw data?

for example, if the raw data is 69696969696969. Does the raw data just get tacked on the end just like this?

lf io clone --vn 1 --fc 242 --cn 38944 69696969696969

You don’t need the raw data, the VN FC and CN are the access control data for the card shown in your picture

The raw data is just that info in hexadecimal in some format, kantech’s XSF format in this case, I believe

Indeed… raw data can be useful if the proxmark3 can’t determine a facility code and card number from the data. It can give you an option to just write the raw data to the target without any known format. Sometimes helpful.

As far as I can tell the io prox clone command doesn’t have a raw option sadly

Hmm. Probably an oversight… but in theory you could manually set the analog front end options yourself with a block write command and then update the data blocks with raw data.

@Iceman are you aware? or is there a reason for the lack of raw data option on the PM3

While we’re talking about it, it would be super cool if the command auto decoded the wiegand from the XSF(): format…


Into plaintext for the user I mean, not as an input for the cloning command

Thanks for the help but Im still a little lost. Where/how do you find the VN, FC, CN info in my data?

Sorry you’ll have to really dumb it down for me, but I’m sure this post will help a lot of people in the future

No problem at all, I only know because I asked a very similar question not too long ago:

From the XSF(01)F2:38944

(01) is the Version Number
F2 is the Facility Code in hexadecimal (It needs to be converted to decimal)
and the 38944 is the Card Number

Ok things are starting to come together. How do I convert f2 to a decimal? is there an online tool that’s commonly used?

I use a python one, there are phone apps, and if you Google “hex to dec converter” you’ll find lots of them, here’s a random one:


Ok man I got everything copied now. I’m going to go try it at my condo be back in 30 min with an update


Works man thank you so much for the help


Most likely since nobody added it…


I feel the need to clarify,

The pm3 project is the result of over 200 different developers, it never had a unified design or architecture from the beginning.

One of my contributions was to have a vision and forging the project towards that vision.

We did a good effort in unifying things but much is left to be wished for.
