"Faxes still have their places. When I moved to another state there was a screw up with DL. Now My choices were to drive back to California and hand delver the documents they wanted. Mail them and it will get there when it gets there or fax it(no they would not take email) Faxing it allowed me to clear it up in under an hour vs mailing it."
And yet, for various security clearance I've had over recent years, emailed scans of documents have been acceptable. In some cases, an "authorised person" in our company has to put eyes on the originals and sign off that the scans are true and correct, but not in all cases.
