Sucessful impant of a $2.80 868 Byte NTAG216 animal NFC chip

Looking forward to your results...

I hope this works out

Woah, I missed a lot, forgot to bookmark this one. I appreciate you all for bringing up very valid concerns.
I'll look at running a lead test soon, the most accessible locally are intended for paint testing. There's the 3m Lead Check which is proprietary, and the Resene lead test (Sodium Sulfide). Sodium Sulfide sounds a better option. I don't think I have the capability to run a quantitative test. -
Can't open the pic from site.
This pic I got from seller after ringing bells... -
Yeah, it seems like they are falsely claiming standards compliance. Mine definitely is picked up with my phone's nfc reader, so I'd assume it's useless at 134.2khz
-
@rodanco those sellers usually have hundreds of products. They make one or two pages then copy and paste for all the other products. Seems like they just didn't care check the info was correct.
Could also be false advertising, these tags are for animals and FDX-A, FDX-B,ISO 11784/85 are a big part of that industry.
I'd stay away from those standards because there is very little DIY equipment available, and you need a reader that can deal with the encryption. 125khz or 13.56mhz will give you the most versatility.
Unless of course your goal is to get chipped and have a vet scan you...then everything I said is pointless.Best is to always question the seller and get the info directly. Later I will post my story and trouble so far regarding that.
I can't see your photo btw.

Purchase date: 3 May 2018
Test date: 7 Aug 2018
Tested with Resene Lead-Based Paint Test Kit (Sodium Sulphide, hydrated 40-45 gms/L)After an hour there was no visible color change. The test paint sample from the kit did turn dark black.
Added bonus I now know my very old flat isn't painted with lead paint.

@Nama Once again, I'm not looking at these now to implant and I said if I need one tomorrow will definitely be DT, we are all just investigating niw... I want to make a ring with 2X ntag216, 1X 125kHz and 1X mifare classic 1K with UID changeable (here I didn't found capsules only coils so will try to "reshape" those)...
-
@rodanco I just ment that the animal specific encodings used will be a pain for reading/writing. I was looking at a 134.2khz with 'memory' also but couldn't find equipment that said for sure it would write to the memory section.
one ring to rule them all?
For the ring you prefer the capsules over open coil?Changing the coil shape will change the resonate frequency but I'm not sure how much in your case. If it is only a little then you lose a little range, if it changes to much then the chip won't get power. If you could recoil the antenna then you could keep the range.
Or you might be able to break a capsule and replace the chip with a 1K chip from a card
-
@bentpins its nice to see the results, and about your paint :P
I'll get the test doc finished and add your data
-
@nana
Yeah, one ring to rule them all, Hahahaha
Stupid auto saving feature....
Added a schetch of my idea. Except the Mifare with backdoor l, all will be capsules, maybe with a tritium one also for night guidance. Will try to figure it out with the antena...So the ring is like the sketch, square and fully transparent
-
@rodanco
it will be a cool project.
Maybe open a new thread for it to keep all the ideas together.Have you ever seen just the IC chips for sale, without antennas or pcb?
-
@nama I'm sorry didn't got your question. For the Nfc with the changeable UID found only chip with coiled antena either in a plastic tag or just simple...
Good idea, will create when I get the products and start on it.
-
@rodanco I mean only the little black microchip with nothing else. So far I've only seen the same as you, so if we wanted to make our own circuits we would have to take apart tags or cards.
Also tried looking for capsule antennas but couldn't find the correct type.
-
@Nama, you can find plenty of the ones like in the link, with changeable UID even and different diameter in coil, for both frequencies, you just need to scroll a bit more, after that look at similar products...

Ps: spoke with a guy from asiarfid.com, they have a lot of implantable products, take custom jobs and they dont seem shady...would be cool for someone to make tests on some of their products.

Well wonder about it now.
