PROBLEM TO BE SOLVED: To settle small-amount dealings on the Internet, etc., by using a card. SOLUTION: Credit is given to small-amount dealings on the Internet, a credit amount sum, a credit period, a credit frequency, etc., are evaluated to decide specific conditions to be met at irregular intervals, and then small-amount credit is totalized and billed for a user. When the user pays for credit to dealings other than the small-amount dealings, the billed amount of the small- amount dealings is added to the bill and details regarding the credit to the small-amount dealings are e-mailed to the user each time credit is given. |
