A remote control device transmits a request for elevator service while a passenger is some distance from the elevator; the call may be assigned to an elevator car, but the car stops for that particular passenger only if the call is verified by the passenger approaching the immediate vicinity of the elevator. In one embodiment, tags identifying beacons that cause requests to be made remotely of, in proximity with, and within the elevator identify the location from where each request is made. In other embodiments, which may use key operated devices, limited-sensitivity receivers, or receivers with directional reception patterns, including overlapping patterns, may be utilized to distinguish between elevator call requests made remotely and made in the vicinity of the elevator. Other methods of verifying presence of the calling device at the elevator may be used.
