This disclosure relates to the prevention of theft of information from the information stored in a card which can perform non-contact communication. A non-contact communication card having an interface for communicating information in a non-contact state communicates with, for example, an external non-contact communication apparatus only within a designated period of time. A user may be allowed to control the execution of non-contact communication by providing a card with an input component which designates permission/prohibition of communication. Providing the card with a recoding component which records a communication log allows the user to check which kinds of non-contact communication have been executed.
