Abstract
A method and system provides conditional allowance of access by operating a movable barrier such that access is not granted unless another condition is met. In one illustrative approach, a first signal is received and, if a second signal is received within a set time frame relative to receipt of the second signal, a movable barrier operator is then activated. By one approach, one of the signals is a long-range transmission, and the other signal is a visual-range transmission.
