1. An information access system for accessing information in a contactless information storage device, said information access system comprising:

  • a passive contactless information storage device capable of transmitting and receiving signals in a contactless manner;

    a fixed-station information processing device including;

    a unit for processing information, and a wireless transmitter which both transmits, in a contactless manner, a command signal for requesting transmission of information that is stored in said passive contactless information storage device, and supplies power in the contactless manner to said passive contactless information storage device; and

    a mobile-station information processing device including;

    a unit for processing information, a unit for presenting information, and a wireless receiver for receiving a response signal for response to the command signal, from said passive contactless information storage device in a contactless manner;

    wherein while said fixed-station information processing device is supplying power to said passive contactless information storage device in the contactless manner, said passive contactless information storage device transmits, in response to the command signal, the response signal to said mobile-station information processing device in the contactless manner.
