I can scan the NFC and RFID sides of my NeXT chip on readers, but when using the Proxmark3 to write to it, I cannot find it for the life of me when doing an lf search. I’ve been trying for a half hour.
Is there a command I can run that can show me signal strength in realtime as I move the device around my hand to find the optimal position for reading and writing?
It took just under two weeks on my left hand and I think just over three weeks on my right to get reads. I found the HF read first and a few days to a week later, the LF. Both in L0 and R0 respectively.
I will say that the NFC is detected by my phone immediately and I can scan the RFID side on a standard reader, I just cannot connect with the proxmark. I’ll wait for now until I’m able to successfully connect.
The PM3 is notoriously tricky to get a good coupling, especially on implants that are a little deeper.
I am assuming you have done some reserch on the forum to find placement suggestions
Here’s an example
This is a shit answer, and I have never suggested this before, but a cheap confirmation could be something like grabbing one of these
