Smartcards aren't the same as SmartMedia - the latter is just a memory thing. Smartcards are a whole platform, used for an awful lot of things.
As already mentioned by someone else, they're used in some national health systems - I think Germany as well as France - to hold a patient's records, so they can be called up wherever the card is presented. And they're also used in both physical and electronic access systems, eg locks or TV decoders.
GSM SIM cards are also just smartcards for a specific application - the first generation had th esame credit card form factor, and even now many SIMs will be delivered that size, leaving the user to push out the chip and a little bit of plastic if their phone uses the smaller factor more common in modern phones.
You'll also find smartcards used in payment systems, like the Mondex electronic cash system trialled in Swindon a few years ago (http://www.mondex.com/). The Netherlands and Belgium have payment systems using smartcards too, called respectively Chip-Knip and Bancontact Mister Cash, if I remember correctly.
And if you have a french credit card (and some others now - the French were early adopters) it is a smart card. Pay by card in a Paris restaurant, and you'll usually be asked to key your PIN into a portable reader brought to the table. No slips for people to take, no signatures to be copied...
Unfortunately, the credit card form factor is just a little too big for a flush springboard. But it could be a potentially very useful application, similar to the 'wallets' envisioned by Mondex.
In that system, say you run a market stall, and want to accept payments from people with an e-cash card. You'd just tap the amount on the screen of your Visor, then slot the customer's card into the reader. The cost is removed from the balance on their card, and when you put your own card in the reader, it's transferred to yours.
Given the number of things smartcards are used for, certainly in Europe, perhaps it's only a matter of time before someone comes up with a Visor module.
Those who really want to know more could try http://www.smartcardforum.org or one of the many other sites covering the area.
