Patent ID: 7499549

Claim:
A communication system for communicating data, comprising: a first information processing apparatus, including a first radio communicating portion configured to judge whether authentication processing is performed for communication between the first information processing apparatus and a second information processing apparatus based on a user input user's operation, perform the authentication processing, when authentication processing is performed and the second information processing apparatus is within a range of a communicable distance of the first radio communicating portion in the first information processing apparatus, register authentication data, obtained from the authentication processing, said authentication data being required for communication between the second information processing apparatus and the first information processing apparatus, and a second communicating portion configured to communicate data with the second information processing apparatus, based on the registered authentication data, said second radio communicating portion having a longer communicable distance than that of the first radio communicating portion; and the second information processing apparatus, including a third radio communicating portion configured to perform authentication processing, when the first information processing apparatus is within a range of a communicable distance of the third radio communicating portion in the second information processing apparatus, register authentication data, obtained from the authentication processing, said authentication data being required for communication between the first information processing apparatus, and the second information processing apparatus, and a fourth radio communicating portion configured to communicate data with the first information processing apparatus, based on the registered authentication data, said fourth radio communicating portion having a longer communicable distance than that of the third radio communicating portion.
