atFAX is a web-based, cloud-hosted fax service for organisations that still rely on faxing. It provides a virtual fax number and lets users send and receive through email, multifunction devices, and smart mobile devices. Incoming faxes can be delivered to email and printed at the same time. Outbound attachments may use PDF, TIFF, JPEG, or Postscript formats. The service names Sharp, Canon, Fuji Xerox, and Konica Minolta as supported multifunction-printer brands, and each line can handle up to five concurrent faxes. Security features include 256-bit AES SSL encryption, user authentication, and delivery restricted to registered email addresses. Existing fax numbers can usually be ported. Setup takes up to 24 hours after required information arrives, while porting can take up to 10 days. A fair-use policy prohibits bulk faxing and spamming. The fax-number plan costs 5.00 USD per month, with local and national transmission charged at 11.0 cents per minute; international rates require referral to atFAX.
