Patent ID: 7406323

Claim:
A communication system comprising an information processing terminal and an information processing device, wherein: the information processing terminal comprises: first providing means for automatically providing, a first time, identification information of the information processing terminal by wireless communication to the information processing device, upon positioning the information processing terminal in proximity with the information processing device and before registering the information processing terminal; first acquiring means for acquiring, from the information processing device, communication information for performing communication with the information processing device by wireless communication, and a password; and first communication means for performing wired or wireless communication with the information processing device, wherein: when an instruction to connect to the information processing device is given, said first communication means accesses the information processing device based on the communication information acquired by said first acquiring means, transmits the identification information a second time and the password to the information processing device, and performs communication when communication is permitted by the information processing device based on the transmitted identification information and password, wherein: the information processing device comprises: second providing means for providing predetermined information by wireless communication to the information processing terminal, which is positioned nearby; second acquiring means for acquiring, the first time, the identification information from the information processing terminal by wireless communication; first storage means for registering the information processing terminal by storing the identification information acquired by said second acquiring means; second communication means for performing wired or wireless communication with the information processing terminal; and second storage means for storing the communication information for performing communication by said second communication means and the password, wherein: the second providing means provides, as the predetermined information, the communication information and password stored in the second storage means to the information processing terminal; and the second communication means performs communication with the information processing terminal when said second communication means receives the identification information the second time and the password transmitted from the information processing terminal, and it is determined that: the identification information received the second time is identical to the stored identification information received the first time; and the received password is identical to the password stored in said second storage means.
