Faxing is growing in popularity

Every single hotel that caters corporate clients in the USA still uses fax. We don't get reservations through fax, but that is the best way to get credit card authorization. A lot of corporate booking systems are automated to send out Fax for credit card authorization after they book the room online.

Also, it's much better for our Front desk staff, as they don't have to constantly check the email. There is only 1 fax number, and anyone can send out the fax and whoever is working at the front desk gets a printed copy without doing anything.

I really wish there is a modern alternative to FAX.

Edit: What I mean by a modern alternative to Fax is that the sender can send high-resolution color documents without going through multiple steps. Scan documents to a computer, convert to PDF, Send an email with an attachment, Check email periodically, Print Email.

I have converted most of our documents to digital forms, and sync to all computers. Yet all my employees rather copy documents as they think its much faster and convenient. They will make 100s of copies of the document.

We accept all documents through email or fax. Last week we received an email with a one-page contract that was broken into 4 images. We asked to send it again and they rescanned and send it again the same way. I used a word to print 4 images into one page and call it a day.

What about them? (Can you send a fax over those media, and are they protected similarly?) Or are you asking a different question?

If it's not on a phone line, then it's not afforded those legal protections. None of those communication media you just mentioned are using a phone line as a transport mechanism. (They're also not similar to fax from a UX standpoint.)

The intelligence community has been intercepting faxes for decades.[1] It's not very secure. Even worse, VoIP systems recognize fax modem signals, decode them, transmit them as data, and re-encode them as fax modem signals.[2] They have to; VoIP has such awful jitter and bandwidth that you can't send modem signals over it. So it's easy to peel off the fax data and log it. This is done routinely using fax servers.

Mail delegation covers "anyone can send it out" and 'there is only 1 fax number". Automatically print covers "paper automatically appears" and "don't have to constantly check the email".

What exactly are you hoping to modernize (other than "technology A has been around longer than technology B"). If it's hardware e.g. a physical fax machine with a physical line and you want to get rid of that line there are existing options to do that with or without getting rid of the fax machine and with or without changing the workflow to some other technology stack like email.

If it's "fax is insecure" I agree but until that actually becomes a problem for the businesses on the other end nobody is going to care enough to deal with the change.

One of my former clients was eFax, which parlayed the money it earned from eFax subscriptions into becoming a publicly-traded internet holding company behemoth. They own dozens of second-tier internet media and e-telecommunications sites.

There's a lot of money in fax.
