Abstract

A barrier actuating device is placed in close proximity to an authorization device. Electromagnetic enabling information that has been automatically sent from the authorization device is detected. Responsive to the detecting of the electromagnetic enabling information, an operation of the barrier actuating device is enabled so that the actuating device is operable to transmit a signal. The operation of the actuating device is disabled in the absence of the enabling information.
