The diagram illustrates how an electronic tracking device can track a person by using a machine. There are 3 basic stages in 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 a car. The location of the device is monitored by satellite. A message is transmitted from the device to a mobile phone. 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 Internet website. The device is able to provide details such as the name of the person or pinpoint a specific place on a map.

The electronic tracking device can help us to communicate without distance. This can also help to find the information that we want. It is used to locate a missing person when he/ she is in danger.
