Abstract: A key management program causes the computer to operate as a position information acquisition unit, a key use condition acquisition unit, and a lock releasing processor. The key use condition acquisition unit acquires key use conditions including a lock releasing time and identification information, and key use location. The lock releasing processor transmits lock releasing signal to release locked state to key management device, if current time is within a range of lock releasing time and identification information included in key use conditions also matches identification information of communicating key management device, and position information acquired is a location preset as key use location.

Abstract: A wireless communication device has a first wireless communication unit configured to wirelessly communicate with an external network, a management information storage configured to store application management information received through the first wireless communication unit, a second wireless communication unit configured to wirelessly communicate with an external communication device, and a management unit configured to control, based on the application management information stored in the management information storage, information wirelessly transmitted and received between the second wireless communication unit and the external communication device.

Abstract: A mobile wireless device has a first communication unit configured to perform proximity wireless communication with a communication device, a certification unit configured to perform a certification process between the mobile wireless device and the communication device via the proximity wireless communication using the first communication unit, a second communication unit configured to perform proximity wireless communication with an extra mobile wireless device, and an operation controller configured to control the extra mobile wireless device via the proximity wireless communication using the second communication unit, after the certification process is normally completed.

Abstract: A wireless communication device according to an aspect of this invention includes a main body antenna to communicate with the antenna of a wireless card, and an antenna position setting unit capable of setting a plurality of types of positional relationships between the antenna of the wireless card and the main body antenna.

Abstract: In an IC card, authentication information used for authentication processing in an external apparatus is stored in a memory, and a counter which counts the number of times of executing read processing with respect to the authentication information is provided. The IC card counts up the counter every time an authentication information read request is received from the external apparatus. The IC card reads the authentication information from the memory and transmits the read information to the external apparatus in response to the authentication information read request when a value of the counter is less than a predetermined upper limit value, and prohibits reading the authentication information from the memory when the value of the counter is not smaller than the predetermined upper limit value.
