Hi Guys,
Im not sure if this is posted somewhere before(i was not able to find it)
But what is the best practice after beeing installed with a new chip?
1: should i run the DT APP and set a passcode?
2: Should i run NFC Tools to do initial setup?
What do most of users do? im afraid to start scanning my tag around before i know how its working, i wont to be sure i dont “Fu**k” it up by locking it or something like that.

Is it an xNT or a NExT? I only ask because the NExT has its config bytes protected by default. If it’s an xNT then download the “Dangerous NFC (BETA)” app and apply a password to your xNT.
You don’t have to be super worried about fucking up your implant. The only reason you need to protect the config bytes is if you were trying something weird or untested. Normal reading and writing isn’t an issue.
After you’ve done that, here is a short guide to writing a record to your implant with Tagwriter app.
Hi @Satur9, thanks for reply.
Its the xNT.
Ok, then i will run the app before i start doing something else.
Thanks for the guide.
But as an example, would this just work “out of the box”?
1: my office scan my hand/tag to give it access to office.(its supported)
2: My gym scan my hand/tag to give access to gym(its supported)
Will this work out of the box? or will the gym write/overwrite my office tag?

We’ll need to know more information about your office and gym cards. You can scan them with the TagInfo app (also from NXP) and post the info here. Refer to this post on how to share TagInfo scans. Make sure to censor any sensitive information, like the UID under “Detailed protocol information”
If you can’t scan them with any apps on your phone, it’s possible (though not guaranteed) that they’re Low Frequency cards. If that’s the case you’ll need more a NExT or xEM and more advanced tools to clone them.
Hi Again,
I dont need to clone it as my office can write(as a new card) to my chip.
And i can discard my old access card 
IF it is compatible/supported, and the system administrator is willing to enroll them, then
YEP
Both your office and your gym will have the same UID ( from your NExT ) associated with you, allowing you access to their separate systems. 
Hello everyone! I’m new to the forum so excuse me if this isn’t the right place to post this. I find it all quite confusing on whether or not I have to start a fresh tread. I’m too anxious for that.
Years and years ago (I think around 2021?) I let myself get chipped with an xNT chip.
I was never really into biohacking, or bodymodding or anything like that, I just saw that you could get chipped and took the opportunity because it was all new and I’m just very impulsive.
I put a rickroll on it, and let people scan it. For these few years it’s just been a cool partytrick. Just a song that I can play from my hand.
But… can I actually do anything with it? I have one of the “older” models I think.
I feel at this point that it might be useless, but maybe some nerds here have some good ideas on how to use it.
Absolutely you can. I have a NExT, which is effectively identical to the xNT for purposes of this discussion. The chip that talks to cell phones is also an NTAG 216 just like your xNT. This has actually been my most used implant out of 3 I’ve had installed.
What can you do with it?
-Unlock a door
-Unlock a car
-Unlock a safe
-Log into a computer
-Put your contact info on it
-If you have an SO, they can leave little notes on it for you
The NTAG 216 is older and simple, sure, but that’s part of what makes it so great. Usage is widespread, and so many devices are compatible with it in some shape or form.
Nah, no worries. This is a forum for questions like that. If you post in the wrong spot your message will get sorted out later.
Thank you for the kind response! I worry a lot less now.
I guess I have known about the usages, but I don’t have a car, I do not have the ability to change my lock right now (rental) and I do not have many valuables that I would need a safe.
I think putting contact info on it would be nice, maybe something like your blood type or something like that, in case of an emergency. But nobody is really going to read that out, right? If I get hit by a car, they are just going to dump whatever blood they have lying around, in me.
I just feel like this could only make MY life great, and my life ONLY. It seems to have no widespread usage to other things around me. Nobody around me has a chip either so I can’t like communicate with anyone. I was the youngest person that got a chip in my country (literally the day I turned 18) and the shop that I got it done at doesn’t even do it anymore.
How do YOU use the chip? Have you guys built any cool platforms or done anything like really ‘out there’ with it?
My NExT has / had 4 uses:
1- I have an offbrand HF KBR1 that I use to log into my personal desktop.
2- My SO sometimes leaves little notes on it for me to read later
3- Occasionally I need to distribute wifi credentials at my job. When users ask me for these credentials, I will often have them hold their phone out and I will tap my arm to their device, depending on what phone they have. Saves me some time, lessens some germ contact to my palms.
4- Previously the LF side was programmed to access control for my workplace before we moved onto a better system.
Haha what’s the context here?! I have to know the backstory!
Honestly I just saw it on the news somewhere that this one tattooshop in my country was chipping people. I’ve always been a big fan of tattoo’s, piercings and the whole cyberpunk-esque stuff so on my 18th birthday I had one of them babies stuffed inside me.
My father is very much against self-expression, so it was kinda a middle finger towards him. Being young and all that stuff haha… (I am not regretting anything btw. I still love tattoo’s and piercings and honestly these chips are the coolest things ever if only it was more widespread!)
But the place doesn’t chip anymore. I haven’t found a shop near me that does. I remember when I got it that people had these light up ones, which I thought were so fucking cool. I still kinda want them.
Interesting.. what shop is this?
To add my 2 cents here, I used to use mine for basic credentials storage. It helped in a pinch when I’m using a separate credential for every service in my homelab, although it is still in plaintext. It’s in my L0 which has proven to be difficult to read, so I figured that security through obscurity was best.
I’m getting it replaced with the xDF3 as soon as I can get it removed, after finding out about ChipVault for Android to keep those credentials much more secure. Also the upgrade from approximately 800 bytes to 8k bytes is to look forward to.
I share the same sentiment with you. The future is here and it’s wonderful what can be done. Getting shut out because, “why would you do that to yourself” is ridiculous, especially when you try to show your passion to him. As soon as I get the xDF3 installed, I’ll be hitting double digits of implants, so do what you want! 
I’m sorry I keep pressing on reply but then it doesn’t show it the way when you reply. So sorry if this is creating a mess and all that.
I got it pierced in Tilburg (Netherlands). I see that there is a shop in Eindhoven that supposidly does it now. I see that they only use the NExT one.
Also, you can get it removed?? How would you even do that? It’s so tiny!!
Can you get it replaced?
Also: back then I wanted to get the one where you could pay with the chip, but I didn’t like that you had to add money to an account on your phone. It just seemed like a whole hassle to deal with.
Let me reach out to a dutch buddy who recently got his first implant. He seemed to like the place.
Anything that goes in can come out with blades and effort. There are multiple methods, but the simplest seems to be making a 3-5mm incision near the end of the implant and coaxing it out.
There is this article detailing on getting it removed. I’m hoping for a clean and easy replacement, but it’s never usually easy or clean so here’s hoping!

Not at all, you’re all good.
Yes, my buddy went there for his NExT2 install. Says they were very accommodating.
I figured out how to reply!!!
And yeah I did see that one in Eindhoven! Maybe I’ll go there someday! Thanks for all the help everyone
