摘要：
Document monitoring provides a measure of document security. Documents incorporating radio frequency identification (RFID) tags can be monitored by appropriate interrogation components for movement activity. A surface suitable for placement of documents is configured for monitoring RFID tagged documents. Such documents can be monitored in a document processing device to control access to the document processing functions.
