A lobby detection device 100 placed in a lobby reads out an ID of an elevator user 300 from an individual identification tag 400 and transmits the ID to an authentication device 600, the authentication device 600 registers the ID if the ID has not been registered and performs a call registration for an elevator car 500 after an authentication processing, a car detection device 200 inside of the elevator car 500 reads out the ID from the individual identification tag 400 and transmits the ID to the authentication device 600, and when the same ID as a registered ID that has been registered becomes no longer transmitted from the car detection device 200, the authentication device 600 deletes a registration of the registered ID after a specific time elapses, so that even when the ID is read out by the lobby detection device 100 in the lobby where the elevator user 300 lands on at the time the elevator user 300 leaves the elevator car 500, a call registration is not performed since the registration is held.
