摘要： PROBLEM TO BE SOLVED: To provide an encryption information automatic update system which periodically and automatically updates an encryption key and easily inputs the updated encryption key to a radio slave unit.SOLUTION: An encryption information automatic update system 1 comprises: a radio communication unit 32 which establishes radio communication with a terminal 5 by encryption information; an NFC (Near Field Communication) card 6 which stores ID information; a card reader/writer unit 44 which reads the ID information stored in the NFC card 6; an encryption information generation unit 22 which generates new encryption information and sets the new encryption information in the radio communication unit 32; a storage unit 25 which stores an ID information list 251 indicating ID information of terminals that are authorized to perform the radio communication; and an ID information management unit 23 which writes the encryption information in the NFC card 6 via the card reader/writer unit 44 when the ID information read by the card reader/writer unit 44 from the NFC card 6 is included in the ID information list 251.
