Ah... I didn't see that. Yes, that seems like a good way of creating
the association, and no extra hardware / software is needed at the
card reader to make it work.

I still like the idea of a smart card instead of a generic RFID
card, but I can see how the higher cost of the cards and card
readers might put a crimp on things.

Like you say, maybe you launch the concept with "budget" cards
and card readers. If the idea really catches on, perhaps people
wouldn't mind spending a bit more to include extra data programmed
into the smart card.
Do many hams carry PDAs with them? You could add an interface
to intercept "business cards" beamed by infra-red and connected to
the same TNC that the "HotSpot" card readers are connected to.
A microcontroller could take the received text and convert it into
something useable for APRS.
