GPS-enabled school uniforms hit Japan

With GPS-enabled school uniforms on the way in Japan, the timeless parental refrain "don't forget your jacket" is about to assume new significance.

According to gizmo hub Engadget, the jackets, in addition to letting parents track their kids, sport a panic button that children can push in an emergency, immediately summoning a security agent to their exact location. The GPS-enabled blazers are made by school uniform maker Ogo-Sangyo, with GPS technology provided by Secom, which previously teamed up on a kids' backpack with built-in GPS.

RFID tags have been used to track kids in Japan before, and they've been considered elsewhere, including the United States.

But the notion of electronic IDs in schools has proven more than a little controversial, with some calling them a cutting-edge way to monitor attendance and keep kids safe and others assailing them as an assault on the youngsters' right to privacy.

The student tags employ the same technology used in building access badges commonly issued to employees for security purposes.

Drivers who sign up for quick-pay toll programs use similar devices to cruise by toll booths. And RFID technology has recently been found in chain stories, libraries and casinos.
