I got my implant done a month ago and have been playing around with the NFC side with my cell phone. I finally got my Proxmark and the new cylindrical antenna but have been having a lot of issues trying to read the implant before trying to program it. I cant seem to feel it under my skin anymore and went to get an x-ray to make sure nothing weird happened:
judging from my scar it appears to have migrated a little bit but not dangerously too far? Does the antenna look broken or just offset at an angle?I think i’m using the right commands on the Proxmark (I was able to program the T5577 card that came with it) easily enough, and with a LOT of fiddling I was able to couple (I think) to my implant with the original Proxmark LF antenna. I cannot get coupling at all with the Cylindrical antenna. Heres the commands I am using and the output (with new antenna that is able to read my T5577 card):
