The present invention relates to a mobile phone which has a GPS device and a power control unit embedded therein, has a password device attached thereto, and tracks the location of the mobile phone even if power is turned off. The mobile phone including the password device can be tracked by using the GPS device, a communications network, etc. when an input signal is received by the password device. When a correct password is inputted in the password device, the GPS device, the communications network, etc. are turned off. However, the GPS device, the communications network, etc. are turned on when the password is not inputted therein, thereby tracking the location of the mobile phone. Accordingly, when the password is inputted, the location cannot be tracked, but when the password is not inputted, the location can be tracked. |
