Abstract
An exemplary elevator system includes at least one elevator car. An access controller is configured to provide an access credential to a portable wireless communication device responsive to a request from that device indicating a desire for at least access to the elevator system. The access credential at least temporarily indicates that the desired access should be granted. A credential receiver is configured to obtain the provided access credential from the portable wireless communication device. An entry device allows the desired access responsive to the credential receiver obtaining the access credential.
