One would think that e-mail, FTP, instant messaging, and other methods of transferring files would have killed the fax machine, but the antiquated tool is still alive and kicking, especially in the business sector. Fortunately, you no longer need a dedicated fax machine (and the associated phone line and ink) to send and receive paperwork. eFax, an Internet-based fax service available in over 3,500 cities and 46 countries worldwide, gives you a real fax number that you can use to send and receive faxes—using your inbox.
