Abstract
A document processing system in which a server subsystem stores information corresponding to a document containing human readable and machine readable information and a client subsystem receives the document and interprets the machine readable information. The client subsystem contacts the server to verify validity of information in the document using a communications network that allows information to be exchanged between the server and the client.
