Abstract
A method and apparatus for verifying destination calls needed in an elevator system. In the method a person having entered a destination call is identified first on the floor level outside the elevator and again in the elevator car allocated to the person. The destination floor call received from a destination call device as well as starting floor information obtained from a detector used to identify the person having entered the call are transmitted to the elevator control system, which, based on the destination call, allocates an elevator to the person having entered the call. If the system identifies the person having entered the call when the person is in the elevator car, then the destination call is acknowledged in the system as executed. On the other hand, if the person having entered the call is not identified in the elevator car allocated to him/her, then the previously entered destination call is kept valid and a new elevator is allocated to the person having entered the call.
