I've not asked everyone either but judging by the many comments and given that the core of our support are probably in the 50+ age group I'd say it's unpopular amongst many.
It's not a point scoring or popularity contest though is it? It is clearly causing unnecessary stress and concern amongst, without asking all of them of course, a large proportion of our fanbase. As both the phone method and a plastic seasoncard do the same thing, open a turnstile, I can't see why people who want to continue with the card can't.
The phone method is being enforced upon us and because you don't have a problem with it doesn't mean it's right.
