The present invention is an information processing apparatus which obtains identification information of an electronic device and makes communication with the electronic device via a network based on the identification information. When a portable telephone (11) is placed on an input display section (2) of a personal computer (1), a reader/writer built in the personal computer (1) reads a telephone number of the portable telephone (11) stored in an RF tag built in the portable telephone (11). Based on the telephone number, a telephone line is connected between the portable telephone (11) and the personal computer (1). Data is interchanged between the portable telephone (11) and the personal computer (1) via the telephone line.
