Abstract:
1. A communication apparatus comprising: a communication unit configured to perform a wireless communication with a first NFC token comprising first storage media that store therein association information for establishing a wireless connection between the communication apparatus and a data processing apparatus, and perform a wireless communication with a second NFC token comprising second storage media that store therein user identification information for identifying a user; and a control unit configured to respond to a request from the first storage media to set association information, and obtain the association information from the first storage media via the communication unit and store the association information in volatile memory, and after obtaining the association information for establishing a wireless connection between the communication apparatus and a data processing apparatus, obtain the user identification information from the second storage media via the communication unit, and perform user authentication based on the user identification information obtained from the second storage media, wherein in a case in which the user authentication by the control unit is successful, the association information is stored by the control unit in non-volatile memory and a wireless connection is established between the communication apparatus and the data processing apparatus, and on the other hand, in a case that user authentication by the control unit is not successful, the association information is discarded from the volatile memory by the control unit, and wherein the communication apparatus further comprises a clocking unit that clocks elapsed time since when the control unit determines that the association information is valid, wherein in a case that the association information that is determined to be valid based on the user authentication exceeds a preset expiration period, the control unit determines that the association information is invalid.
