Hi all. First post. I have quite a conundrum that i’m struggling with and hope someone can help…
I have a gen1a FlexM1 installed (3 weeks ago - distal dorsal forearm) and cloned my work ID (Mifare 4K) to it using proxmark. It worked immediately and has continued to do so, but only for SOME of the readers I have access to at work…
i.e. some readers don’t detect it at all, rather than it being detected and rejected.
I’ve also previously cloned my work ID to a ‘Chinese magic’ writable fob, and the fob works on all the readers. So even though the written content on the chips should be the same, the implant isn’t being detected by some of the readers.
I thought it might be swelling related, but at 3 weeks post-implantation there has been no improvement. The implant site is very superficial and there’s no bruising, tenderness or swelling. And it has worked consistently with the same readers from the very beginning.
There are differences in the readers - some are black, and some are white. The implant is detected by SOME of the black readers, but none of the white ones. I would have thought that if there was some difference in the hardware of the readers it would affect read range of the fob, but that seems identical between readers.
Imagine my frustration! I wonder whether a Gen2, or an xM1 would give the same result.
Thanks for your thoughts.
