I emailed the department that handles everything badge related. I told them I had a ring with an NFC chip in it and asked if they could enroll the UID for me to use it.
I received the fastest response I have ever received from anyone at work.
“no sorry company badges only”
I mean literally less than 30 seconds. Got a good laugh out of it anyway.
I still can’t get a read on the NExT, but I think I know why.
It just occurred to me today that all of the readers are mounted directly to metal buildings.
I figured this was bad, but I googled it just to be sure, and sure enough HID specifically says not to do it, and if you have to, to use a spacer (no spacers here).
