NFC Tools is a great app, but the one place it lacks compared to TagInfo is NFC Tools Chip identification is not always 100% accurate, So it’s likely that you have an ultralight, but not certain.
A TagInfo scan would allow a me to provide a more accurate reccomendation.
What I would suggest is …hmmm…the easiest thing would be,…get your self an NTAG216 test card ( A fob would be better ) (a chinese pet implant would be ideal)
THEN
IF you own the lock
this is where you would try and enroll the NTAG216 you purchased from above, and if it works, I see a NExT in your future, I can’t guarantee it will work with your lock due to the size of the NExT, the ability to couple will be reduced compared to a Card / Fob.
You could check the Matrix, ( Also mentioned above ) to see if your lock is on there and if it has been tested as compatiable
If you don’t own the lock, you will have to do the same thing, BUT you will have to convince the lock administrator to allow you to enroll your test card/ fob/ implant.
Does that all make sense?
