Contactless ic card

An application selection method for a contactless integrated circuit (IC) card that can execute a plurality of application programs,

• wherein the contactless IC card has a plurality of antenna coils, each generating an electromotive force by receiving electromagnetic waves from a reader/writer, and
• the method comprises:
• measuring the electromotive force generated by each of the antenna coils;
• comparing characteristics of the measured electromotive forces;
• and
• selecting one application program based on the comparison and executing the selected application program.

A program for a contactless integrated circuit (IC) card that can execute a plurality of application programs,

• wherein the contactless IC card has a plurality of antenna coils, each generating an electromotive force by receiving electromagnetic waves from a reader/writer, and
• the program causes a computer to execute the steps of:
• measuring the electromotive force generated by each of the antenna coils;
• comparing characteristics of the measured electromotive forces;
• and
• selecting one application program based on the comparison and executing the selected application program.
