Keeping tabs on your kids with RFID

Talk about your overprotective parents: a subsidiary of Japenese telco NTT West Corp. has decided to market a system enabling parents to monitor their at-school kindergartners with their home PCs. And you thought your elementary school recess monitor was bad. The system plants cameras around classrooms and playgrounds, and the students wear name cards equipped with an RFID tag, exposing their every move to invisible parental eyes. All of the kid-info is relayed home to the obsessive parent over the Internet. The system includes 4 cameras, 80 RFID tags and costs about 3 million yen (around $30,000).
