 7 World Trade Center is equipped with Otis destination elevators . After pressing a destination floor number on a lobby keypad , passengers are grouped and directed to specific elevators that will stop at the selected floor ( there are no buttons to press inside the elevators ) . This system is designed to reduce elevator waiting and travel times . The elevator system is integrated with the lobby turnstile and card reader system that identifies the floor on which a person works as he or she enters and can automatically call the elevator for that floor .
