NFC goes peer-to-peer, won't help you download next week's Lost premiere

Near-field communication, or NFC, has been slowly but surely creeping its way toward mainstream adoption, and this latest announcement by the NFC Forum, rulers of the 13.56MHz frequency, should only help things to go more smoothly. It has announced the Logical Link Control Protocol (LLCP), enabling NFC-compliant devices to talk to each other. We're not talking massive transfers on a gigabyte scale here, rather things like contact infos, web addresses, and surely other types of secret message ("UR Cute!"). Along with LLCP comes the new NFC Signature Record Type Definition (RTD), which not only yet another acronym but also entails a new way of digitally signing those messages, theoretically preventing their being usurped and used for evil purposes -- like recess blackmail.
