Next, the fourth step (S42) is that the user's computer 1 usage information is stored in the storage means 30 when the tag 10 possessed by the user via the control means 50 is out of the recognition range of the RFID system. Is stored in the computer 1, and the computer 1 is converted into a secure mode, thereby limiting its use.

Through the above-described 4-1 step S44, the security mode is released and the tag 10 of the user who is using the computer 1 is repeatedly read by the RFID reader 20 to see if it is within the recognition range of the RFID system. . At this time, if the same tag 10 ID information is repeatedly read and transmitted to the control means 50, the control means 50 maintains the security mode release state. On the other hand, the time interval for the RFID reading means 20 to transmit the radio wave to detect the tag 10 is set by the administrator through the application program as described in the second step (S20) described above. When the security mode is released in such a way that the user of the computer 1 with the tag 10 carried away from the recognition range of the RFID reading means 20, the RFID reading means 20 is no longer the same tag 10. Since the ID information is not transmitted to the control means 50, the control means 50 assumes that the user has left the computer 1 and converts the computer 1 into the secure mode. In addition, the control means 50 converts to the security mode and at the same time calculates the first reading time and the last reading time of the tag 10 ID information corresponding to the user's computer 1 usage information, and builds it in the storage means 30. The calculated time is stored in the computer usage time field among the generated database fields. Therefore, the administrator can accumulate the computer 1 usage information of the user authorized to use the computer 1 and utilize the information as human resource management information and business management information.

(If ID mismatch)

Finally, the fifth step S50 is a step in which a security mode for limiting the use of the computer 1 is maintained when the IDs compared in the comparing means 40 through the control means 50 do not match. When the control means 50 receives the result of determining that the ID information is inconsistent from the comparison means 40, the control means 50 maintains the security mode state so that the owner of the tag 10 in which the ID information is stored cannot use the computer 1. .
