So, this prob isn't the place, but instead of cards or short range radio, I thought plugging into headphone jacks and having the phone do transactions (akin to what short range radio would do). Doesn't require any modification to phone and is backwards compatible with almost all phones (that have their won sdk (Symbian, iOS, Android, RIM) or use J2ME or BREW.

I wouldn't be able to bring this up myself (I just do code, hardware and banking is beyond me at times), but I would never object to being included with people who could:-D

Anyway, ::shrug::, just thought I'd place the idea out there since I feel it's good and like to see someone do it.
