PROBLEM TO BE SOLVED: To provide a master point card system which can analyze a commercial area, a customer distribution, etc., without making stores feel loss or unfairness and saves labor in promotion. SOLUTION: A master point card where predetermined master points (10,000 points) are stored is inserted into a card terminal; and the master points (10,000 points) are added to the remaining master points and stored, and the points (10,000 points) are subtracted from the master points of the master point card to set the master points to zero. When the customer makes a purchase, the points corresponding to the purchase amount are issued and subtracted from the remaining master points (10,000 points), and the issued points are added to the current points of the customer card and displayed. |
