Internet faxing, or ‘online faxing’, relies on a similar principle to email. Internet faxes are transmitted via providers like eFax, who encrypt your fax with TLS encryption , transmit it digitally, and de-encrypt for you to read.
Unlike traditional faxing, internet faxing does not require a fax machine, an analog fax line or a fax file room. Instead, internet fax users fax from their computer, smartphone or tablet. When a user sends a fax, it is transmitted online - instead of through analog fax lines. However, internet fax users still use fax numbers, as service providers use fax numbers to direct the faxes to the correct recipient. When a user receives a fax, they receive an email-like notification on their device. The user is then able to access their fax online, where it is stored with cloud-based storage.
Internet faxing is made possible by service providers like eFax. eFax currently transmits over 1 billion faxes monthly and has over 11 million customers worldwide.
