Abstract
A method of identifying proximate mobile devices, the method comprising the steps of: providing a sensory identifier (ID), a first mobile device (1) detecting the sensory identifier (ID), a second mobile device (2) detecting the sensory identifier (ID), the first mobile device (1) sending a request message associated with the sensory identifier (ID) to the second mobile device (2), and the second mobile device (2) sending an acknowledgement message to the first mobile device (1) so as to establish mutual identification. The sensory identifier (ID) may comprise a visual identifier, such as a bar code, and/or an audio identifier, such as a sound signal. An audio identifier may be produced by tapping the mobile devices together.
