Can I copy a HID Proximity Card to my xEM?

Hi all, first off I appreciate any and all replies.

My work uses a card that has ‘HID PROXIMITY’ and the numbers 01440 stamped into it, and it appears to be identical to this reader: Smart R Distribution Ltd - THE Access Control Distributor

Boss has given me the green light, and now I’m just wondering the how. I haven’t needed to copy onto my xEM before as i had just had it added to my previous workplace instead, and I was just hoping someone could tell me if I was correct and it was this simple:

I have a proxmark 3 on the way in the mail, is as simple as just reading then writing? I know with my xNT chip some cards simply cant be cloned onto it, is there a similar situation with the xEM?

Again, I appreciate all replies.

Thanks, Ryan.

for 99% of LF cloning it’s simple read and writing which, depending on the exact chip in your card will be doable with the proxmark

From my experience it’s as simple as lf search and then lf hid clone -r xxxxxxx to the t5577. Just be mindful to maintain a good coupling, and IIRC @amal suggested somewhere sometime the ability to add a delay between when the command is issued and the command is executed. Though, I might be mistaken on the who, but I’m sure of the what. I’ll do some digging and see what I can find.

Knew it was there somewhere. Hadn’t had a chance to dig for it yet. Thanks!


So after running pm3 → lf hid clone -w H10301 --fc 164 --cn 125 , both my xEm and proxcard appear to be the same - I cant test it at the office until next Tuesday, but until then does this look correct to you?\

Thanks a bunch for the replies everyone!


yep looks good to go!
