To provide an information processing service system capable of improving convenience by eliminating a physical action such as putting in money or loading a card.

When an IC card 102 gets closer to a copying machine 101 and communication is started, configuration operation is performed and the copying machine 101 recognizes that the communication equipment of a party is the IC card 102 (S105). A personal information identifier (personal authentication ID) is received from the IC card 102 (S502). On the basis of this ID information, the copying machine 101 displays the confirmation message of whether or not a function is to be used on an operating part thereof together with the ID information (S503). When the user presses an OK key as a message confirmation, the copying machine 101 inquires the authentication of the personal information through the Internet 104 to an electronic settlement authentication server 103 (S508). When the result of inquiry is OK, processing for permitting the use of the copying machine 101 is performed (S509).
