In an era dominated by digital transformation, the humble fax machine may seem outdated. And yet, it remains one of the most secure and reliable ways of transmitting information across medical providers and systems.

For healthcare providers, especially those managing prescriptions, a fax number remains a critical part of running a compliant and connected clinic.
