The Australian National University started issuing certified electronic Academic Transcripts, Australian Higher Education Graduation Statements and Testamurs from mid 2010. This is via the Digitary service based at Dublin City University. Instead of providing a certified paper copy or a scan of it, students can provide a hypertext link to the document in the on-line service. Copies printed from the service have instructions on them of how to verify the details.
This is a much more secure and convenient system, than trying to verify a paper copy of a document, or a facsimile of it. A university can provide such a service directly, via its own web site, but using a service shared by other universities (including the University of Cambridge and the London School of Economics) increases the credibility of the documents.
