Abstract: An exemplary apparatus includes a sensor, control circuitry, and an alert mechanism. The sensor is configured to sense one or more users entering a passageway. The control circuitry in communication with the sensor and a credential reader, and is configured to count a number of the one or more users entering the passageway, to count a number of authorized credentials presented to the credential reader, and to transmit an alert signal based upon the number of the one or more users and the number of authorized credentials. The alert mechanism in communication with the control circuitry, and is configured to perform an alert operation in response to the alert signal.

Abstract: A method operates a server that is coupled to a network controlling door actuators at physical geo-locations. The server receives through a wireless communication network a request to enable physical access at a portal using a secure channel and a geo-location estimate from a mobile device. A circuit of the mobile device receives radio signal magnitude, phase, and power from at least one transmitter and authentication input from a user interface. Dual secured communications paths protect the server on its separately provisioned request channel and actuator command channel. Each legacy electronically controlled access portal is enabled to support smartphones without installing a replacement multi-band radio frequency reader at the geo-location.
