Fan update won't stop much.
Touts will evolve, memberships will just go in peoples names, friends/family members etc.
The only thing that would stop it is pictures on tickets but that would cause so much chaos it would be unworkable.
For example, our four tickets change hands so many times during the season we have had to buy our own burner phones to put them onto, there are rarely the four owners at the game two weeks in a row.
They don't usually go further than brothers/sisters or kids but they do change a lot and a picture would cause a lot of aggro and this happens all over the ground every game.
I don't know what the answer is but I'm pretty sure whatever they will do touts will find a way around it.
