Abstract
A contactless integrated circuit (IC) card (11) is comprised of the following: a first antenna coil (102) and a second antenna coil (103) for generating an electromotive force by receiving electromagnetic waves from a reader/writer; a first electromotive force measuring unit (311) and a second electromotive force measuring unit (312) for respectively measuring the electromotive force generated by each of the antenna coils; an electromotive force comparing unit (313) for comparing the characteristics of the electromotive forces which are respectively generated by the respective antenna coils and then measured; and an application selecting/executing unit (215) for selecting one application from a program storing unit (216) based on the comparison made by the electromotive force comparing unit (313) and executing the selected application.
