<p>An RFID (Radio Frequency Identification) element (10) is mounted on a protected piece of goods, e.g. a wristwatch (1). It may be in communication with an RFID reader (2) on a mobile telephone with a SIM (Subscriber Identity Module) card (3). The video display on the mobile telephone can give the relevant patent details (30). The mobile telephone is in communication with a first server (5) via a radio network (4). The server can send query signals (50,51) to further servers (6,7) with data banks containing patent details (71). Answer signals (60,70) are returned to the first server.</p> |
