I just freshly got the xSIID implanted by a professional but I cant read or write anything to the NFC. The detectors that came with the kit dont pick up anything and neither does my phone. However, the high frequency KBR1 reader I also got detects it just fine and outputs its serial number as it should. Is there something im doing wrong to get the NFC to work? Tried multiple positions and orientations with no success. Got the implant today.

The detectors aren’t meant to detect the implant. They are meant to show you the best spot for the implant to be read by readers

If it’s recently implanted, you have a LOT of blood/inflammation hanging out on and around the implant which, IME, hinders it being read/written to. It took about 8 days of healing before I could use my first one and about a month for the second. Just depends on your body “getting out of the way”

Okay thank you for the reassurance, just wanted to make sure everything was as it should be.

If it’s been recently implanted it’s probably fine, it just takes a little while for the inflammation to go down to get a good read. Taking your phone outside of the case is also super helpful.

It can take up to 2 weeks for it to read reliably. And a bit longer for the xSIID to light up as brightly as it can.

I’ll jump on this bandwaggon. I got a NExT in P0 Left and an xSIID in P0 Right on the same day. It took about a week to get good reads from my NExT and 3 weeks to get good reads from my xSIID. Bodies are weird.
Also, it took me some time and practice to learn how to orient my phone to the best position possible to read either of them reliably.
You will get there! If the KBR1 sees it, you’re in fine shape and just need to wait a while to get good reads from other sources.
I might also point out that iPhones have a significantly more difficult time with implants than most Android phones do. And even within iPhone or Android, different models have widely varying NFC strength. (See Amal’s video for iPhone tip!) So also matters what device you are using to read/write.
I hope you get a lot of satisfaction from your new hardware!
