NONCONTACT TYPE INFORMATION PROCESSING MEDIUM, DECIDING METHOD FOR OPERATION STATE IN THE SAME NONCONTACT INFORMATION PROCESSING MEDIUM, NONCONTACT CARD AND DECIDING METHOD FOR OPERATION STATE IN THE SAME NONCONTACT CARD

摘要

PROBLEM TO BE SOLVED: To provide a noncontact card which makes it possible to visually confirm whether or not the operation is possible and whether or not an internal circuit system, element etc., function effectively. ;SOLUTION: This noncontact card 1 which performs information transmission between it and external equipment by the transmission and reception of signals through radio, is provided with a card type base material 2, an antenna 3 and an operating voltage generating circuit 12 which are incorporated in the base material 2 and generate an operating voltage corresponding to the signal intensity through the radio from the external equipment, an LED 5 which is arranged in the state of appearing on the base material 2 and a control part 11 which turns on and controls the LED 5 when the operating voltage generated by the operating voltage generating circuit 12 is higher than a specific voltage.;COPYRIGHT: (C)1999,JPO
