A company called bladerunner has a jacket with a GPS system inside. It cost $500, and for $20 a month your parents can always see where you are (or where your jacket is!) . But that's nothing . Do you parents want to know what you‘re eating ? No problem. MyNutriKids tells them what you‘re having for lunch at school. Do your parents want know your exam results? GradeSpeed is a service which gives them that information. Do they want to know what online conversations you ‘re having? IMSafer tells them. You usually arrive on time for extra-curricular sports classes. But if one day you don‘t arrive on time, there‘s a service which informs your parents. And there‘re another service which sends them a message if you go outside a specific area.
