Think twice before stealing that Coke, kid. The Japanese city of Osaka has got your number — via a seriously high-tech method of crime prevention. They'll be outfitting vending machines with surveillance cameras (to be called "Unmanned Police Station Robots" — eek). The best part? The cameras will be triggered by kids bearing RFID tags with push buttons. In an emergency, kids will trigger the tags and the nearest vending machine will start snapping pictures of the area and beaming them back to the police mother ship. Incidentally, the RFID chips will be serving a dual purpose: to track the kids. Is anyone surprised?
