Abstract
A method and call system for an elevator car located within a building that may react to a passenger's approach and arrival in front of the actual elevator door. The system makes use of a sensor located near to an exterior door of the building containing the elevator, and a second different sensor located near to the actual elevator bank in which the arriving passenger would intend to enter. The system may also make use of identifying a passenger based upon a predetermined identification or authorization to include automatic communication through to the elevator for initial entrance floor location as well as an exit floor location based upon the predetermined passenger's identification and/or authorization.
