Electronic document issuing method has check character code printed onto issued document transmitted back to document provider for allowing document verification upon presentation

摘要

The document issuing method has an individual data set in the form of numbers and/or alphabetic characters for a singularly identifiable reference object transmitted via a public data network from a document provider to a document issuer, with a check character code generated within the processor of the document issuer and printed on the issued document. The check character code is transmitted to the processor of the document provider, for allowing the issued document to be verified upon presentation.
