"Find my child" tracking system via cell-phone

Find My Child provides peace of mind for parents, allowing them to locate their children via their mobile phone. This can be done without having to make a call (which they often don't answer) or sending a text message (which they sometimes ignore). A people locator service such as this is designed to locate the phone of another person. For the service to work, the phone has to be switched on and within network coverage. Location services aimed at children are intended to complement, not be a substitute for, normal parental supervision. They give information about the location of a child’s phone and, in conjunction with other types of communication, such as texting, can help parents keep in touch with their children.
Although the technology that is used is sophisticated, the service itself is very straight forward. Free trail and buy options are available for the UK at present.
