<P>PROBLEM TO BE SOLVED: To achieve smooth unlocking/locking of a locking object by a key device through the use of portable equipment individually possessed by an operator. <P>SOLUTION: Firstly, a bar-code reader performs a connecting operation (S100). A key device is brought into a connection time-out state by the start of electric power supply, and determines whether or not authentication is performed, when determining that a connection request from the bar-code reader is made. In this case, the key device transmits its own pass key when the authentication is not previously performed. The bar-code reader urges a code to be read (S120) when the pass key is transmitted (S110: YES), and establishes a communication line (S140) by performing collation with the transmitted pass key when the reading of the code is completed (S130: YES). <P>COPYRIGHT: (C)2013,JPO&INPIT |
