1. A method of operation for a Virtual Door Knocker system includes processes comprising:

  • at a communications device with sensors,storing a credential associated with an authenticated user;

    determining operation by the authenticated user;

    receiving geolocation signals;

    determining propinquity to a controlled portal;

    receiving accelerometer measurement vectors corresponding to force impulses;

    determining a match with a stored pattern of force impulses;

    upon verification of user, location, and pattern of impulses, exchanging credentials and transmitting a physical access request;

    receiving on a wireless communication network, an authenticated physical access request from the communication device in vicinity of the controlled portal; and

    transmitting the request to a portal controller;

    at a credential server,creating, managing, and delivering at least one valid credential to at least one communication device from a plurality of communication devices and to at least one portal controller from a plurality of portal controllers;

    at a provisioning server,providing to the portal controller, configurations of the plurality of portal controllers, and the plurality of communication devices which conditionally support physical access control at the time and place;

    at the portal controller,receiving an authentication credential from the credential server;

    determining from the provisioning server a condition when the portal is accessible to the authenticated user;

    receiving the request to access the portal by the configured communication device; and

    enabling operative power to a portal locking mechanism;

    at the portal locking mechanism,receiving electro-magnetic power to actuate an electro-mechanical device; and

    enabling access through the portal.
