Out of interest why don't you want the club having pictures of you?
If you have a driving licence or passport those pictures are stored.
A private corporation should never hold that kind of personal data of their 'customers'. Regardless if it's a 1 time use. Comes back to the post Hillsborough idea of all football fans having ID cards to stamp out criminality. Guilty until proven innocent
But the biggest reason is very simple. The club allows passing on tickets/ST etc to friends/family as long as you are not doing so for profit. Do you have 2/3/4 photos on a card? Should someone be pulled in every single match because his/her face doesn't match the one on the card because the card belongs to a mate that cant afford his season ticket that season.
It's a very difficult situation the club is in (and has been in for a very long time). You can either be a family club that allows everyone in (and leaves the club open to touting) or you can be the police state that has a strict policy of knowing exactly who is in every single seat in the ground (no touts but punishes 'regular' fans going to the game).
At the very least the club finally has clearer policies on policing ticketing issues with a clearer appeal process (though the club should be doing more). The club needs to have an innocent until proven guilty policy.
This may be an unpopular opinion but I would rather have 5% of the ground filled with touted tickets for every game than have even 1 single innocent fan having to go through the process of having to prove that he/she belongs in their seat or worse having a fan innocently losing their ST or fan card because they couldn't get to a game and passed it onto a mate.
