PROBLEM TO BE SOLVED: To provide an IC card capable of informing a card processor that the number of times of non-matching in the collation of identification(ID) information approaches the limited number of times before the number of times of non-matching arrives at the limited number of times, when the ID information is supplied to the IC card. SOLUTION: A collation means 13 in an IC card 100 collates 1st ID information stored previously in a 1st storage means 16 with 2nd ID information supplied from a card processor via a 1st interface(I/F) means 11 and writes the number of times of non-matchings in the collation in a 2nd storage means 17. When the 2nd ID information is supplied from the card processor, a control means 14 generates a warning information when the number of times of non- matchings is the preset number of times or more and less than the limiting number of times and supplies the warning information to the card processor via a 2nd I/F means 12 before the execution of collation by the collation means 13. |
