<p>PROBLEM TO BE SOLVED: To provide a non-contact information exchanging device which can discriminatingly and securely use plural functions displayed by plural semiconductor devices without operating a semiconductor device controlling other antennas which should not receive electromagnetic waves although the structure is simple. SOLUTION: Non-contact information exchange cards 1 and 1a are equipped with one antenna 3a and the other antenna 3b which exchange information without contacting with an electromagnetic wave from the outside 13 and semiconductor devices 5a and 5b which have functions of controlling the antennas 3a and 3b respectively and processing the information, and a shield member 17 which cuts off the electromagnetic wave 15 from the outside 13 is arranged between the antennas 3a and 3b.</p> |
