Abstract: This document discusses, among other things, systems and methods for preventing fraud in remote service inquiries in medical and other environments. An individual may be able to register only one device per profile. The doctor approves each patient and the device prior to the patient being allowed to call a phone number associated with the nursing triage service. When the caller uses that device, the teller is able to confirm that the register device is associated with the patient. This provides an additional layer of security without requiring caller to identify the phone number.
