A security system control system using a host object with a near field communication device and a target object with a near field communication device. The target object broadcasts a carrier signal to the host object. Using the near field communication device, the host object modulated identification information on the carrier signal and broadcasts the modulated signal. The target object demodulates the signal to determine if a user associated with the identification information is authorized to perform the intended control function. The target object determines the intended control function based upon a detection criterion. The target object causes the intended control function to be performed if the associated user is authorized to control the intended control function such as to arm or disarm the security system. The identification information can expired after a predetermined period of time. The target object updates the identification information after expiration.
