A computer-implemented method a sequence triggering of a call for an elevator car of an elevator system. The elevator system including a first location device and a second location device. The computer-implemented method including detecting, by the first location device, a signal by the mobile device and detecting, by the second location device, the signal by the mobile device. The computer-implemented method also including automatically executing, by the elevator system, the call for the elevator car in response to the detection by the second location device of the signal subsequent to the detection of the signal by the first location device.
