There was concern that data exchange would occur. For example, when an unused telephone card or various pre-built cards are placed in a conventional wallet, etc., when going to a place where electromagnetic wave signals come and go, unnecessary data exchange occurs, and as a result, unused contactless IC cards are used. There was a concern that the card would be used up.
