I have replaced my fax entirely with a digital camera and email. Faster, more compact, impossible to falsify, doesn't require a phone line, and of course, nobody can dial into my camera.
The printer attached to my computer prints, copies, and scans. It's not like it was expensive. Less than $200. I can email any document that I have without the phone or long distance charges, and the quality of the document is better than what a fax can deliver.
I don't know why fax machines are still in use, to be honest.
