If I were more confident that they'll actually get it right I'd be fine with my local transit authority once again delaying its deadline for new
fare card system proposals. The most difficult part is, I think, designing a system which is simple and easy to use for both regular and occasional riders. The existing system is, if not perfect, good enough for commuters who purchase weekly or monthly passes (these are priced high enough that they're not worth it for anyone other than daily commuters). It just sucks for occasional riders because they make it very difficult to actually purchase a token or train ticket.
