Electronic babysitter keeps track of children

Children may not like it but a British technology firm has invented an electronic babysitter - a wristwatch-like device that lets parents know where their children are at all times.

The GPS Child Locator, or NuM8, attaches securely to a child's wrist and contains a Global Positioning System, said Matthew Salmon, a spokesman for manufacturer, lok8u.

"It starts working when the device is connected to the child's wrist," Salmon said. "Even if the child managed to get it off it would send an emergency text message to your mobile phone with a Google Maps image with their exact location, the street name and zip code.
