The application implements National Security mandates from government and quasi-government standards bodies to secure Critical Infrastructure. Specifically, the application layers biometric verification for users entering secure facilities using physical credentials such as magnetic stripe cards and NFC tags. In addition, the application provides for collection of high accuracy geocoordinates in the background for users as they traverse through secure facilities in order to track and trace in case of theft, vandalism, and terrorism. The location collection is done for additional purposes of occupancy determination of building and zones in case of emergencies such as fire, terrorism, flooding, etc.
