"Released into beta earlier this month, tikitag uses short-range, high-frequency RFID to let consumers and third-party application developers connect everyday items to online content or applications. To tap the connection, users of the technology need only touch a compatible device such as a cell phone to an item tagged with a corresponding sticker. "

RFID for the masses. Not sure of the real-world uses yet, but definitely cool, and not that expensive. So much so, that I've got a pack on order already... stay tuned.
