Abstract: A system and method for monitoring a presence of an individual in a geo-fence relative to a central facility. The invention effectuates tracking of field workers for home health and home care as well as a plethora of other applications. The invention provides real time data on the duration of time the care provider spends with a patient while holding the care provider accountable for being on site for the duration of care. In a most general embodiment, the invention includes means for receiving and storing geo-fence data on a first mobile computing and communications platform; logging time at a location defined by said geo-fence data; and transmitting the time log to a second computing platform. In a specific embodiment, the invention includes means for biometrically identifying a care provider within the geo-fence and outputting data to the second computing platform with respect thereto. The biometric identification may be implemented with fingerprint, voice print, facial recognition or other suitable means.
