A function for processing electronic money is installed in a mobile phone 7 provided with a contactless IC chip. At this time, an electronic money member number is written to the contactless IC chip. The user accesses a point site on a point server 10 through a user terminal, and logs in thereto. The user enters the electronic money member number in the point site. The point server 10 transmits a combination of the electronic money member number and the user's point member number to an electronic money server 2. The electronic money server 2 receives the electronic money member number and the point member number from the point server 10, and memorizes them after establishing a linkage therebetween.
