Maybe found a card disguising it self as a mifare classic 1k 14443-A tag or I'm missunderstanding something, please advice

Thank you for explaining that!
And yes I have been wondering to, cause I get UID with 4 bites one way and 7 bite the other.

The different commands produce these different outputs:
hf mf info - UID: XX XX XX XX
hf mfp info - UID: XX XX XX XX
With — Fingerprint
[=] Size… 2K (4 UID)
[=] SAK… 2K 7b UID ← This I dont understand

Double checked taginfo app:
UID: XX XX XX XX

Same outcome as before.

And I think they use the two extra sectors at work in some way, cause I can let my self in through the door with the implant, but I can’t “clock in” at the reader by the door, once inside and clocked in, the implant works with all the doors it needs to work with, but not unless I have clocked in.

It’s still a partial win for me.
