<p>A system for reducing security risks in, for example, an enclosed area where there are documents, computer discs, and other items which may contain security sensitive information. Each security sensitive item has an RFID tag attached thereto, and during non-working hours these items are placed in locked file cabinets, a safe or a vault. The area is periodically interrogated by an RF interrogator to ascertain whether the items are in their locked secured position or are in an open area.</p> |
