Well, there are already cards that do that at gas stations (and the like) that do swipe payments. That's something I'd like to see more of. But also quite different than transferring music files and such.
It's not different at all, other than the fact that proximity cards are dumb while NFC (near field communication) objects are smart. They use the same basic technology (magnetic induction between two loop antennas) and NFC has a peer-to-peer mode for transferring data between two devices, supporting speed of 424 kbits/second (double that is available but not common). If that speed is insufficient, they can also be used to create near-instant bluetooth pairings to quintuple that.
It is very likely that Apple will have NFC in the iPhone 5 this fall. It's likely that they'll provide this kind of data transfer, at which point 3rd party manufacturers will hop all over it.
