Secondary Short-Range Wireless Assist for Wireless-Based Access Control

An access control system comprising:

• a processor;
• and
• a memory that stores computer-readable instructions that, when executed by the processor, cause the processor to perform operations comprising
• receiving a first identifier via a near field communication reader associated with an entryway to an area, wherein the near field communication reader receives the first identifier from a near field communication component of a mobile device,
• receiving a second identifier via a wireless transceiver associated with the area, wherein the wireless transceiver associated with the area receives the second identifier from a wireless communication component of the mobile device after the mobile device has entered the area through the entryway, and
• determining that the first identifier and the second identifier constitute an authentication pair, the authentication pair identifying the mobile device as being authenticated to access the area.

A computer-readable storage medium having instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:
