The objective of the present invention is, with respect to a portable terminal which is provided with an electronic money function, to facilitate restoration of an original state if a terminal has been discovered, while preventing unauthorized usage of electronic money at a time of loss for a terminal which is provided with an electronic money function. If a terminal is lost, an electronic money server is accessed from a second terminal in order to perform a loss lock request. The electronic money server turns ON a loss lock flag corresponding to an electronic money ID in order to output a negative flag ON instruction for an electronic money function section at a point at which access has been made from the terminal. For the electronic money function section, by turning ON a negative flag, the electronic money function section is locked so that settlements and charges are disabled.
