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.

Description

technical field

[0001] The present invention relates to a non-contact integrated circuit (IC) card, in particular to a non-contact IC card which can execute a plurality of application programs and facilitate the user to select an application program. Background technique

[0002] Magnetic cards, including credit cards, have been routinely used regardless of their purpose, such as commercial purposes. Recently, however, magnetic cards have given way to IC cards. Possible reasons include that the IC card has a low risk of tampering and is superior in security and large storage capacity, and that a non-contact interface can be applied to the IC card through wireless communication with a host terminal. IC cards with these advantages are extremely popular in the transportation field. In particular, these effects have been confirmed in the processing of ticket checking that requires a large capacity and high speed, and its future application in various fields will be further con...
