So I recently got the NEXT chip implanted in my right hand and I was a little to eager to get it working. I bought an RFID reader and writer off amazon
and I scanned the chip at 125 KHz and it worked. I grabbed my student ID and read it to copy it to the chip. It read fine but when I wrote it to the chip it said “write failure” and it no longer reads the chip at all. Any help would be greatly appreciated.I tested the xNT end and that still works great
Perhaps it’s worth trying to write the card to a fob and seeing if it works?
The card writes to a fob with no problems
Any chance of getting access to another reader or a proxmark?
I can look into a proxmark, any recommendation on where to buy a reliable one from

Or if you are at DEFCON the DCBHV might be able to take a look at it.
Thanks
So i got my hands on the proxmark and it does not seem to be able to find my chip (No Known Tags Found! is displayed). I tried some of the cards they give you to write to and they seem to work fine.
Sounds like a big oof moment
It might have clipped while writing to it. If you look through the forum I think this has happened before. Not sure if there is a way to fix it though.
