Mini USA, manufacturers of the delightful Mini Cooper, have stumbled on a novelty advertising idea of dubious security. Using information stored on and broadcast from the key fobs of Mini owners driving past, these billboards deliver personalized messages to them. I wonder if there are really enough drivers with these RFID chips to make these signs an effective campaign, but its only in four cities so I suppose they aren’t spending too much on it. More importantly, every Mini owner is broadcasting personal information so far around them that a sign dozens of yards away can pick it up as they fly past at freeway speeds. Anyone else have no desire whatsoever to own a car that does this? I really want to know what info is on those keys, and why in God’s name they decided to do this is beyond me. Via Swismiss.
