PROBLEM TO BE SOLVED: To confirm the content of data or the presence or absence of update without requiring any special reading machine for reading information by a user with respect to a capacitive data card. SOLUTION: Relating to this capacitive data card a first anchor layer 42, conductive data pattern layer 43 forming a capacitive data pattern, and protecting layer 44 are successively formed on one face of a substrate 41, and the conductive data pattern layer 43 forms an input and output device being a closed circuit including an in-card circuit through an air capacitor so that the input and output of data can be operated with the input and output device. A second anchor layer 46, reversible thermosensitive recording layer 47, and protecting layer 48 are successively provided on the whole part or at least one part of the other face of the substrate 41. |
