If you are only using the prepay feature then you do not need a photocard.
You only need one if you load a season ticket onto it.

Actually, since you never actually have to open the wallet, how do
"they" know whether you have a valid photocard or not?

I've been asked for the photocard once. (It's been checked by a person
about two dozen times in the same period).
