BTW, I believe this rf technology (like that found in the Suica card or
in EasyPass fobs you find in the US and Europe) is currently being
studied for introduction into credit cards. I believe Sony is one of
the major proponents of this...

My first thought was, "wow, cool! And quite possible with current
technology, too!"
But there seems to me one little sticking point here. How do you prove
you've paid? Show the attendant the screen? How does he know it's not a
Java Applet that generated that screen? Take a ticket, or go through a
turnstile? How do you make sure it's the person right next to the ticket
machine or turnstile that approved that payment, and not the guy behind
or next to him?
Hm. Maybe you generate a barcode (good for a limited time only) that
you then swipe at the turnstile or ticket machine.
