PROBLEM TO BE SOLVED: To change passage authority information by remote control.SOLUTION: A control terminal 2 sets passage authority information, which includes an effective period enabling gate passage and a renewal deadline, in a management server 3, for each user terminal 4 permitted to pass through a gate. In unlocking or locking of a lock device 5, the user terminal 4 downloads the passage authority information current at a current date and time from the management server 3, and transmits the downloaded passage authority information to the lock device 5. The lock device 5 opens or shuts an electric lock 5a when determining that the passage authority information acquired from the user terminal 4 falls within the effective period. |
