Generally, yes. Depends on the NFC controller and software support.
That's how Google Wallet works.

As you have seen, it's a random UID. I don't remember the details off hand, but
a certain range is allocated for random UIDs, so each time you will
get some UID
in this range. You can't fix the UID, at least not with any of the standard NXP
controllers.

What are you trying to do?
