The diagram illustrates how an electronic tracking device can be fitted to someone’s clothing or hidden in a bag, in order to allow that person to be tracked and located. There are three basic stages to the process.

The first stage in the tracking process is to hide the device, (the tracker), in an appropriate place such as a bag or on the person’s clothing. The location of the device is monitored by satellite.

A message is sent from the device to a transmission tower. It is received and then re-transmitted as a text message to a mobile phone indicating exactly where the person is. His or her location can also be picked up on a computer. The device is able to provide details such as the name of the street or pinpoint a specific place on a map.

A device of this nature could be very effective as a means of tracking and locating someone such as a school child.
