<p>A user can play a network game using a game client (108) and receive electronic chips issued according to the score of the game. An electronic chip issuing module (102) dynamically determines the conversion rate from the score to the number of electronic chips in cooperation with a game server (109) with reference to an electronic chip condition calculating module (107). The user can purchase a commodity through a Web-POS client (110) and receive a discount by using electronic chips issued to each user. An electronic chip consumption module (103) dynamically determines the conversion rate from electronic chip to coin in cooperation with a Web-POS server (111) with reference to the electronic chip condition calculating module (107). Since the conversion rates are thus dynamically changed, diverse sales promoting effects are produced.</p> |
