Bernardo got the Triple Play bundle from Time Warner using the Internet, but he has to send them information from time to time via fax. Leo says that's because of them needing his signature. Leo does a rubber stamp JPG onto a PDF file and sends it to them.
Bernardo will need an online service like eFax to send a digital fax. He'll upload a PDF to them and they send it as a fax. He can subscribe if he uses a lot of faxing or just pay as he goes for a few bucks a fax. The chatroom says that FaxZero is free.
