Facsimile, or fax, is a device that lets you transmit documents, be it letters or pictures, using radio or telephone signals and reproduce an exact copy of document on therecipients end. If youre young enough to not know what it is, fret not, were here to remind you what an amazing invention fax is.
1. History
It all started in 1843 yes, that long ago when Alexander Bain invented the first technology to send an image over a wire. Frederick Bakewellthen improved the invention and made an image telegraph that was similar to todays fax machine.
In the 1860s, Giovanni Casellycreated a pantelegraphthat became widely used for image transmission. His machine worked much better than Bains and Bakewells. The concept was improved throughout the late 1800s and 1900s, especially after the telephone was invented. In 1964, Xerox introduced Long Distance Xerography that enabled document transfer via telephone line in a relative short time and its the start of fax machine as we know it today.

2. How the machine works
Dont be like Jackson. Facsimile is not magic and your printer cannot talk to you.
First of all, you scan the original document with your fax machine. Then, the image or text will be processed into a bitmap. The telephone system will transmit the bitmap code in audio-frequency tone form. The receiving machine will get the tone andre-transformit into the original form of the original document.
3. Fax is more secure than youd think!
Common belief might say that fax is obsolete (looking at you, Museum of Obsolete Things Youtube Channel!), but fax is actually still used widely because of its security. In the digital age like this, using emails might be easier and faster, but internet is never really safe. Remember the Sony Entertainment hacking in 2015 that leaked some unreleased movies? Or iCloudhacking that leaked many private pictures of celebrities? Fax wouldnt let that happen. In fact, companies like Sony and some US state agencies opt to communicate using fax to prevent hacking or tempering.
4. Digital fax exists
Its the era of internet but most business players still prefer to use fax to transmit certain documents, for security reason or simply because it is what theyre used to. But people cant bring fax machine anywhere they go, can they? So this is where digital fax comes in.
Rather than going to a scanner and sending all those words in email, you can just put your docs into a fax machine then itll be sent to your recipient right away in the form of apdf, andthey can open it on their mobile phone right away.
