PROBLEM TO BE SOLVED: To increase the use efficiency and the rate of collection of issued points. SOLUTION: A partner database 12 stores a sales conversion rate for converging the points issued from issuing organizations and a purchase conversion rate for converging reference points to the points issued from the issuing organizations in correspondence with the issuing organizations. When a user requests the conversion from converged points to converging points on a page provided by a point information providing part 15, a point confirmation/ notification part 17 confirms to a converging point issuer site 40 whether the user holds the points or not, and confirms to a converted point issuer site 40 whether the user is a qualified point holder or not. When the confirmation is completed, based on the sales and purchase exchange rates, a point calculation administration part 16 exchanges the user points based on the sales and purchase exchange rates. When a member registration is performed, the user can exchange the points to the reference points and hold the points, and also can exchange the points with commodities at a commodity exchange site 50. |
