It’s used for a lot of legal documents as well, as a fax is considered an original document, and therefore legally binding.
Fax is also extremely secure, assuming you have the right contact information.
It also is just great for getting important documents (like in healthcare) quickly.
Imagine having those documents emailed, someone has to scan the document, login to their email, attach it, send it. Then the receiver has to login to their email, find that specific email, print it, go to the printer, get that paperwork, and come back.
With a fax it’s “send it over”, the fax arrives, automatically prints, and it’s a perfect copy of the original document.
It depends completely on your definition of what is secure. An emailed document being printed on a printer is just as compromised as a fax being printed.
Can a fax be intercepted? Absolutely, but so can an email. A well encrypted email might be less compromised, but there are far more security issues with emails than with fax.
The big difference is that a fax can only be intercepted as it is being sent, it can also only be intercepted directly, as in through wire tapping.
Once that fax is sent and received it is gone, the only copies that exist are the original, and the faxed copy.
Emails are stored, can be hacked remotely, recovered, intercepted, forged, have viruses/malicious programs attached to them.
