I don’t know of any readily available phones than can "read" an RFID tag, but they must have ‘em in Korea! The latest use for such a beast is actually a great idea and I wish we saw more RFID applications like this. Here’s the scenario, you’re walking down the street when a movie poster catches your eye. You’re taken in by the story idea (or the picture of a attractive actor/actress…your call) and decide on the spot, you want tickets. The poster actually contains an RFID tag that your phone can read, so you simply buy tickets on the spot with your phone. One SMS confirmation later, you can walk into the theater sans tickets. Sweet!
