FINGERPRINTING A MOBILE DEVICE THROUGH NEAR FIELD COMMUNICATION

Some embodiments include a method of operating an identity receiver of a security system to process an authentication request. The method can include detecting an energy signal from a mobile device at the identity receiver using a first communication protocol; generating a handover message at the identity receiver to request a unique characteristic of the mobile device using the first communication protocol, the unique characteristic associated with a second communication protocol; receiving the unique characteristic from the mobile device at the identity receiver; and authorizing access through the security system by matching the unique characteristic to an authorized identity stored in the identity receiver.
