Dangerous Things Sells “Cybernetic Microchip Biohacking” RFID and NFC Implants

I have their Titan magnet in a ring finger. Unlike all other magnet implants it does not degrade at all because it has a titanium casing, so it will last good as new until I die or remove it.

I can feel AC with it very easily, because the magnet vibrates. Microwaves and laptop charger bricks are fun. There's a little gadget [1], literally just an inductor soldered to a USB-C connector, that you can plug into your phone and test your sensitivity with. Having a literal sixth sense is the coolest thing in the world to me and I haven't gotten tired of it at all about a year post install.

I also have their Next in the same hand that I use to get into my apartment everyday and have a link to my website on (has both RFID and NFC)

I have one between my thumb and index finger. I was aware there are far fewer nerve endings in that area, but was hoping it would still work to some degree, as certain people reported. Sadly, I don't feel anything at all.

Is it a problem if you need a MRI?

If I knew beforehand I was getting one I would have it removed. If not (incapacitated), someone has gone through an MRI with my same magnet and just felt strong tugging, not even really painful and definitely not ripping-out-of-finger strong. It's a pretty small magnet and I guess human skin is pretty darn strong.

How ironic, due to my Internet situation I was greeted with a "prove you are a human" prompt.

Their site force redirects to a relatively useless country-local top-page so I have no idea what TFA is about.

That said, I've been looking a lot into NFC with asymmetric keys since I wanted to use it as a 2nd factor for everything (including phone unlocking, unfortunately that doesn't seem to be happening any time soon).

NFC has a couple implementations: tags (basic, unencrypted, cloneable), symmetric encrypted (all your readers need a shared key) like Desfire... I think these aren't clonable?, and asymmetric which basically requires it to be a full JavaCard NFC chip.

Yubikeys are JavaCards basically. Testing with my computer nfc reader doing a signature is fairly slow (a second or two).

Actual card JavaCards are something like $4 in bulk, and $15-20 for small batches. I'd really like a wrist-band or ring form factor, and I was thinking the dangerousthings implants are small enough they could be stuffed into a band.

You can get a "pocket band" and put a yubikey in it, which works okay. There also are a lot of smart rings, but they're either not passively powered by the NFC connection (need to be charged) or are simple tags and not JavaCard-capable.

That said, they have a bunch of products and an awful website and I couldn't tell what the difference between products was, either (and importantly, which ones were JavaCard and which were basically just tags).

FWIW there is no article in this case. TFA is the shop itself, presumably to start a discussion of biohacking, particularly some of the implants they have.

I've had one of their magnets and one of their NFC chips in my hand for a decade

Similar boat, I have two FlexNTs - one in each middle finger. Funnily enough, the one in my right hand stopped working after about three months. The one in my left has been going strong for the last 6-7 years.

What do you use them for?

My contact card is on the chip, so I can give people my info if they scan it with their phone.

Magnet I mostly use to make sure my laptop charger is plugged in all the way.

They're just kind of fun. I had a couple other magnets too, but they had a different type of coating and had to be removed when they started to leak.

BiOhAcKing as advanced as a paper sticker!

as smart as people plastering qr codes without the url on the side, which you could remember and access later...

Been looking for someone to remove an rfid tag in my right hand from 2005.

Did you inject it in yourself? Or did the person who did it decide they can't remove it?

I've been tempted by the magnetic implants when they first became a thing, but given that later in life I've now required a few MRIs, I'm glad I didn't get it done.

I’ve had magnetic implant and had it removed years later out of a fear of the silicone sheath being penetrated at some point. The person who helped me with my rfid implant is in a different state. But at the time we used an 8ga needle and slide it thru the center.

from what I have seen the DangerousThings / Vivokey implants are MRI safe. I even read about someone with a Titan magnet in there finger getting MRIs and not having any problems.

Don't do this. Don't suggest its safe for others to do. It's VERY not safe to bring anything ferrous or magnetic into the presence of an MRI. You may destroy the device that is going to help save someone's life.

The Dangerous Things X-Series microtransponder may safely undergo MRI diagnostics in cylindrical systems up to 7-Tesla.

as for the Titan Magnets I was just referencing this post

Don't spout nonsense that you're clearly uninformed about. That's not how any of this works. Yes, a large piece of metal is dangerous in an MRI. A three gram magnet in a finger not so much.

I personally know someone that did an MRI with a finger magnet and yes, there's a fair bit to it, but it's plenty doable. Obviously consult your doctor and the tech, but know that it has been done successfully several times.

Eh, there's something serene in the knowledge that I could just get up and walk away from all this technology at any time and just... exist... as a simple no-tech mass of meat. Just getting by with whatever biology gave me.

It's fun to see what other people do sometimes, though. I'm rather tickled by the (currently out of stock) "Pain Management Kit."[1]

does the notech mass of meat uses clothes for the lack of fur in cold climate, glasses for bad eye sight, thousands of tools every day, etc?

I think it's very reasonable to draw a distinction between dumb technology and digital technology, and I suspect almost anyone you talk to would understand that distinction without being precious about it.

Even though I understand your point, technology is technology, I understood what GP meant too.
