Security system providing temporary personnel access based upon near-field communication and related methods

An access control device associated with a personnel access position and comprising:

• a Near-Field Communications (NFC) sensor configured to receive a temporary security code from another device, the other device having a unique identification (ID) assicated therewith and generating the temporary security code based upon the unique ID;
• and
• a controller coupled to said NFC sensor, the
• controller being configured to
• selectively grant personnel access based upon the temporary security code, and
• determine the unique ID associated with the other device.

A security method for a plurality of electronic devices, each having a unique identification (ID) associated therewith, at least one mobile wireless communications device comprising a first Near-Field Communication (NFC) circuit, and an access control device associated with a personnel access position and comprising a second NFC sensor, the method comprising:

• generating a temporary security code at a given electronic device based upon the unique ID associated therewith;
• receiving the temporary security code at the at least one mobile wireless communications device from the given electronic device;
• receiving the temporary security code at the access control device from the first NFC sensor via NFC communications;
• selectively granting personnel access via the access control device based upon the received temporary security code;
• and
• determining the unique ID associated with the given electronic device at the access control device.

A non-transitory computer-readable medium having computer-executable instructions for an access control device associated with a personnel access position and for use with a plurality of electronic devices, each having a unique identification (ID) associated therewith and configured to generate a temporary security code based upon the unique ID, and at least one mobile wireless communications device comprising a first Near-Field Communication (NFC) circuit and a first controller configured to receive the temporary security code from a given electronic device from among said plurality of electronic devices, to perform steps comprising:

• receiving the temporary security code from the first NFC sensor via NFC communications;
• selectively granting personnel access based upon the received temporary security code;
• and
• determining the unique ID associated with the given electronic device.
