PROBLEM TO BE SOLVED: To prevent the forgery of a thermosensitive recording card. SOLUTION: Concerning the thermosensitive recording card, with which a magnetic recording part 3 for recording information and a discoloring part composed of a thermosensitive material to be discolored by heating are provided, information on the magnetic recording part 3 is reloaded corresponding to the frequency of use and heating parts 2a-2f in at least one part of the discoloring part are heated, heating patterns 10a-10f are drawn in an ink so as to be overlapped with at least one part of the heating parts 2a-2f to be heated in the discoloring part. Since at least one part of the heating parts 2a-2f to be heated is overlapped with the heating patterns 10a-10f, when exchanging the discolored part with the other part, it is necessary to remove the heating patterns 10a-10f so that forgery becomes difficult. |
