MAGNETIC PRINTED MATTER, AND METHOD FOR READING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a magnetic printed matter and a method for reading the same in which forgery can be hardly performed, and authenticity determination having high credibility can be performed.SOLUTION: A base 1 in which a symbol string 11 is printed, is provided. The symbol string 11 includes a first magnetic print part 10 printed on the base 1, and a second magnetic print part 20 printed on the base 1. The first magnetic print part 10 includes a first magnetic material having a Curie temperature (TcA) of a first temperature. The second magnetic print part 20 includes a second magnetic material having a Curie temperature (TcB) of a second temperature higher than the first temperature.SELECTED DRAWING: Figure 1
