Happy new NExT implant user here. I have cloned my HID prox card 2 to a test T5577 card as well as my chip using my proxmark3. The chip and both cards work in the elevator and parking garage, but not on the reader to my office (multiclass SE). When using a diagnostic card from DT, the HF and LF led’s blink like crazy.
I have tried searching, but are there any tips or solutions to using the LF side of the chips on these readers?
I have to deal with the same “problem”, if you use your LF xFD to find the antenna sweet spot(s) (brightest), for mine, I find tucking my thumb in, fingers pointing to the floor, placing NExT to the lower middle of the reader and swiping down toward the floor
