here are several devices that are available out there for parents who are worried about where their children are going. Every mobile provider now carries kid-friendly phones that have alarms and GPS capabilities that allow parents to watch via satellite. Recently, Princeton unveiled a tiny device that is designed for finding kids but might be even more useful with your keys.

The Kid Finder is a remote that displays basic directional information and has an alarm for the kid’s side in case of strangers bearing candy. It works up top 90 meters so it is good to keep track of them in public place where you are present. For now the $108 Kid Finder is the best we have but after combining it with a camera, you will need nothing else.
