Had a NExT jammed into me for my birthday last week. Been wanting one for a while, and opportunity knocked, so I answered. Installed by a very experienced biohacker. Pain barely registered, not much soreness afterward, and healed up nicely. 10/10 would jab again.
Background: No stranger to RFID. Cloned HID Prox to many different media, comfortable cloning hotel keys, etc.
Reason I chose the NExT is that I was hoping I could use the T5577 component to ditch this pesky RFID ring, which I got to replace the pesky fob, which I got to replace the pesky card issued by work. I have a friend with one and I helped clone his apartment key to his.
So far my PM3 can write it and read it (with the standard antenna, didn’t even need the coil antenna), it reads identically as my ring/fob/card, but none of the door readers seem to be able to detect it. Is it in too deep? I’ve tried different angles. Do I need to wait until it “settles” or heals internally? It’s in the usual place between thumb and forefinger. I have a couple extra readers in the lab I could wire up for further testing… Love to hear others’ experiences/suggestions.
I had a Next installed 11 days ago in R0. I can read the HF side 90% of the time on the first attempt now. I still cannot get a read on the LF side and the PM3 reports it as noise.
My last Next took about two weeks to heal properly and consistently be able to be read.
Have you tried the field detector keychain on the door readers to get a good sense of location and rotational orientation you should be presenting your implant to the reader with?
Eriequiets suggestion to do an identical clone and test both at the same time is a good idea.
I sounds like you know what you are doing, but one thing you may not be used to dealing with is, the small form factor and the reduced range that comes with it.
Amals suggestion with the xFD will help you find the reader antenna and best orientation
