yes :/

Many commenters say that your data / picture is in the system already, which is fine, but your passport photo can be 10 - 15 years old and these systems record how you look now. That's the question if you are comfortable providing it.

What you can't do anything about is CCTV and I think it's a safe bet that they are already equipped with facial recognition and other ML tracking technologies. It's just a question of which database you can avoid being registered in.
