<p>An electronic security system uses a set of predefined RFID tags (10) each associated with and attached to an article or packaging for an article, and each includes unique tag information which is logged into a computerized database (200) as a record. When a tag is detected in a detection zone by an interrogator (22), the database records are compared to the tag information using a comparator (37) and an appropriate database response is output. When legitimate access to the tagged article is obtained, the tag may be deactivated electronically, physically or virtually.</p> |
