1. A method for verifying that a document is included in a document management system, said method comprising:
- providing a document comprising a scan track having radio frequency readable information;
radio frequency scanning the scan track with a scanner head no greater than about 10 cm in its largest dimension;
generating document data dependently upon said radio frequency scanning;
comparing said generated document data to stored document data, said stored document data generated dependently upon a prior radio frequency scanning of the scan track; and
outputting an indication of the document being included in the document management system as determined by said comparing.

Abstract
A system and method for verifying that a document is included in a document management system is disclosed. This system and method includes scanning of a scan track of a document, generating document data dependently upon the scanning, comparing the generated document data to stored document data, the stored document data generated dependently upon a prior scanning of the scan track of the document, and outputting an indication of the document being included in the document management system as determined by the comparing.

9. A method for verifying that a document is included in a document management system, said method comprising:
-
providing a document comprising a scan track having scanner readable information; optically scanning the scan track with a scanner head no greater than about 10 cm in its largest dimension; generating document data dependently upon said optically scanning; comparing said generated document data to stored document data, said stored document data generated dependently upon a prior optical scan of at least a portion of the document; authenticating the document data using at least one radio frequency scan; outputting an indication of the document being included in the document management system as determined by said comparing and said authenticating; and said authenticating storing any variations in said generated document data as updated stored document data. - View Dependent Claims (10, 11, 12, 13)

14. A system for verifying that a document is included in a document management system, said system comprising:
-
a document comprising a scan track of radio frequency readable information; a radio frequency document scanner comprising a radio frequency scanning head no greater than about 10 cm in its largest dimension; a memory storing document verification data associated with the document; a computing system operatively connected to said radio frequency scanner and said memory; and computing system executable code accessible by the computing system and operative by the computing system to; receive data from said radio frequency document scanner said data indicative of a radio frequency scan of the scan track of the document; generate document data dependently upon the received radio frequency; access the memory to recover the document verification data; compare the generated document data to the recovered document verification data, the document verification data being previously generated dependently upon a prior radio frequency scanning of the scan track of the document; and provide an output indicative of the document being included in the document management system if the generated document data is substantially identical to the recovered document verification data as determined by the compare. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
