1. A physical access control (PAC) system controlling access to a physical access portal, the PAC system comprising:
an authentication device remote from the physical access portal comprising:
physical layer circuitry configured to transmit and receive radio frequency electrical signals with a radio access network; and
processing circuitry operatively coupled to the physical layer circuitry and comprising an authentication engine configured to:
determine presence of a credential device local to the physical access portal;
activate an application of the of the credential device without user input to the credential device in response to the determined presence of the credential device;
open a secure communication session with the application of the credential device using a cloud-based messaging service via the radio access network;
retrieve access credential information from memory of the credential device using the secure communication session;
authenticate the access credential information; and
authorize access for the credential device to the physical access portal according to the access credential information.
