Are you running Windows / Linux / Mac?
What are you trying to read / write?
What security systems do you have access to?
Do you have an NFC enabled phone?
What have you done with your NExT so far?
What do you ACTUALLY want to do?

I gotta say thought, the amount of reading and YouTube watching I did before I even ordered my NeXT… Hell, I had hours and hours of practice on my Proxmark programming and cloning the practice cards before the NeXT kit even shipped. I question the wisdom of getting an implant installed into your body without even the slightest bit of research. It’s kind of frightening actually.


Many people do much more drastic and permanent things on impulse. Not everybody has a 3 digit IQ.

Very true, or we wouldn’t have so many DUIs.

I do hope it’s clear though that I never questioned anyone’s intelligence (IQ). There’s quite a difference between wisdom and intelligence. I mean I’ve met some really smart people that could be talked out of their shoes by someone with “street smarts”.

It was just a figure of speech. Besides, 3 digits isn’t a very high bar nowadays.

Haha, Fair enough… touché.
I could have and would have answered more if there was more info to go on…I also could have spent hours second GUESSING what help is needed.

Just pulling your leg man. No criticism intended.

If the numbers are to be believed it’s exactly half of people.

Na, I got ya :wink:

To give a serious answer to OP, short and sweet. Use the Proxmark on PC to program the xEM portion and NFC Tools Pro on phone to program the NDEF portion of the xNT side. No, you can’t change the UID or use the xNT portion to clone an NFC card. Flash the prox with RRG firmware. Since you don’t have the rdv4, and assuming you have a 64bit OS, use the most recent build from It will have the software for the PC and the firmware for the prox.

For specific how to, there’s a plethora of tutorials on YouTube for Proxmark. The technique will slightly vary depending on which card you are cloning, so you’ll get much better results if you use far more specific search terms on YouTube than in your post here.

Here’s a basic video on cloning HID Prox.
Will give you a basic foundation to build on.
