<p>A article guard system for protecting an article, particularly a mobile phone, from theft or loss and a method of doing the same are described. The system comprises a transmitter unit (100, 200) for attachment to an article and a receiver unit (300) for use with the transmitter unit (100, 200) to receive a wireless transmission of the transmitter unit (100, 200). The transmitter unit (100, 200) encodes a predefined ID code and wirelessly transmits the encoded ID code within a specified range. The receiver unit (300) has a registered ID code and generates an alarm if the receiver unit (300) cannot match the registered ID code with a decoded ID code from a wireless transmission of the transmitter unit (100, 200).</p> |
