PROBLEM TO BE SOLVED: To prevent erroneous registration even when call registration is made using a radio signal by a portable terminal device.SOLUTION: A landing call registration system includes: an NFC reader/writer 8 installed at an elevator hall entrance; radio reception terminals 101-102 installed on an elevator door side with respect to the elevator hall entrance of each floor; a portable terminal having a first communication section to communicate with the NFC reader/writer 8, a second communication section to communicate with the radio reception terminals, and an application exclusively for call registration that starts the second communication section. The application exclusively for call registration is started when the NFC reader/writer 8 authenticates an individual ID of the portable terminal by the first communication section, and then a user transmits the individual ID, and a call registration signal to the radio reception terminal by the second communication section. |
