Abstract

An information display method by use of a card including an information display section which includes a reversible thermosensitive recording portion capable of recording information reversibly therein with application of heat thereto, comprises the steps of (1) storing first information in the information display section; (2) comparing the first information stored in the information display section with a reference information; (3) displaying a second information in the information display section, based on the comparison of the first information and said reference information, and repeating the steps (1) to (3) by updating the first information and the second information when further information is stored in the information display section.

Claims

1. An information display method by use of a card comprising an information display section which comprises a reversible thermosensitive recording portion capable of recording information reversibly therein with application of heat thereto, comprising the steps of:

(1) storing first iconic information in said information display section;

(2) comparing said first iconic information stored in said information display section with reference information;

(3) displaying second iconic information in said information display section, based on the comparison of said first iconic information and said reference information, and

repeating said steps (1) to (3) by updating said first iconic information and said second iconic information if further information is stored in said information display section.

2. The information display method as claimed in claim 1, wherein said first iconic information comprises a plurality of pieces of iconic information, which are successively stored in said information display section.

3. The information display method as claimed in claim 1, wherein said first iconic information is displayed in accordance with the storing thereof in said information display section.

4. The information display method as claimed in claim 1, further comprising the step of making a choice as to whether or not repeating of said steps (1) to (3) should be performed.

5. An information display method by use of a card comprising an information display section which comprises a reversible thermosensitive recording portion capable of recording information reversibly therein with application of heat thereto, and an information memory section for storing information, comprising the steps of:

(1) storing first iconic information in both said information display section and said information memory section;

(2) comparing said first iconic information stored in said information memory section with reference information;

(3) displaying second iconic information in said information display section, and storing said second iconic information in said information memory section, whichever step may come first, based on the comparison of said first iconic information and said reference information; and

repeating said steps (1) to (3) by updating said first iconic information and said second iconic information if further information is stored in said information display section.

6. The information display method as claimed in claim 5, wherein said first iconic information comprises a plurality of pieces of iconic information, which are successively stored in both said information display section and said information memory section.

7. The information display method as claimed in claim 5, wherein said first iconic information is displayed in accordance with the storing thereof in said information display section.

8. The information display method as claimed in claim 5, further comprising the step of making a choice as to whether or not repeating of said steps (1) to (3) should be performed.

9. The information recording method an claimed in claim 5, wherein said information memory section comprises at least one memory section selected from the group consisting of a magnetic memory section, an IC memory section, and a rewritable bar code section.
