<p>A three part security access arrangement in which the first part (1) is associated with an authorised person in the form of, for example a belt buckle, the second part (2) is attached to a valuable item, for example a wallet, and the third part (3) is associated with an area of restricted access, such as a car. Access to the restricted area is denied unless all three parts are in close proximity. If either the first or second parts are absent the third part will not allow access to the restricted area. The first and second parts (1) and (2) incorporate means for providing an audible alarm if they are separated by greater than a pre-determined distance.</p> |
