Information recording card, and information recording and recognition methods using the card
First Claim
1. A card comprising:
- a reversible thermosensitive recording portion capable of recording information therein and deleting recorded information therefrom reversibly, wherein the information recorded in the reversible thermosensitive recording portion is visually displayed; and
an irreversible recording portion capable of recording information therein which cannot be deleted, the information recorded in the irreversible recording portion being substantially the same contents as the information recorded in the reversible recording portion and also being visually displayed;
wherein said reversible thermosensitive recording portion is capable of assuming at least two different states with respect to the color tone and/or transparency thereof.

Abstract
A card is composed of a reversible thermosensitive recording portion capable of recording information therein, and an irreversible recording portion capable of recording information therein. An information recording method uses the card in which an numerical information is recorded in the reversible thermosensitive recording portion, and an information which has substantially the same contents as those of the numerical information recorded in the reversible thermosensitive recording portion is recorded in the irreversible recording portion for preventing improper alternation of the numerical information recorded in the reversible thermosensitive recording portion. The numerical information recorded in the reversible thermosensitive recording portion and the information recorded in the irreversible recording portion are recognized by an optical device.

16. An information recognition system for a card comprising:
-
a reversible thermosensitive recording portion in which numerical information is recorded, wherein the numerical information recorded in the reversible recording portion is visually displayed; an irreversible recording portion in which an information which has substantially the same contents as said numerical information recorded in said reversible thermosensitive recording portion is recorded in said irreversible recording portion, and is also visually displayed; and an information memory portion in which information is stored; wherein the matching of said numerical information recorded in said reversible thermosensitive recording portion, said information recorded in said irreversible recording portion, and said information stored in said information memory portion is judged by information processing means.
