Abstract
A security document is provided comprising a first RFID tag readable only within a first range, and a second RFID tag readable within a second range, the first RFID tag containing data pertaining to the owner of the security document and an identification code, and the second RFID tag containing the same or a related identification code, and wherein the second range is longer than the first range. Also provided is a method and system for controlling access to a region, each person seeking access carrying a detectable unique identifier. The method comprises: detecting, at a first location, a unique identifier relating to a person in the first location; using the detected unique identifier to retrieve information concerning the person from one or more external databases; supplying the retrieved information to a second location remote from the first location; and using, at the second location, the retrieved information to make a decision as to whether to allow the person carrying the unique identifier access to the controlled region.
