Abstract

In an improved filing and retrieval system, documents associated with a name card are scanned for electronic storage, the name card is scanned for electronic storage of its image and the electronic version of the document is associated with the electronic version of the name card. The name card is then stored in a name card file, usually a conventional name card storage system. When retrieval of a document associated with a particular name card is desired, the name card is obtained from the name card file, scanned, and the scanned image is matched to the previously stored scanned image of the name card. Once the correct name card is identified electronically, the associated documents are retrieved.
