StarFax Mobile iOS allows Star2Star users to send and receive faxes on their mobile devices using their StarFax Personal account. StarFax Mobile iOS adds reliable, cloud-based, mobile faxing to your Star2Star system. StarFax Mobile iOS is a modern, environmentally friendly way to incorporate fax into your business workflow without paper, ink, or power hungry fax machines, saving you space and money. StarFax Mobile iOS frees your workforce from the constraints of the office and enables workers to send and receive critical documents anytime, anywhere. Each StarFax Mobile iOS user has a unique, personal fax number for incoming faxes associated with their StarFax Personal account. When a fax is sent to that number, the Star2Star system receives the fax and stores it in the cloud at a Star2Star data center. These files can be accessed on your mobile device from a list of received faxes. Users can view, forward, or download faxes to their mobile. Since the faxes are stored in the cloud, all your faxes are available anywhere your mobile device has an Internet connection. Users can send virtually any type of printable file (doc, pdf, jpg, etc.) directly from the StarFax Mobile iOS application, without printing a hard copy or using a fax machine. Users can even send screenshots or photos taken with their mobile devices. Faxes sent and received using StarFax Mobile iOS are also accessible on a computer using the Star2Star Application Framework.
