PURPOSE: A credit card management apparatus including plural card numbers in a card company server, method, and record medium are provided to prevent the leakage of card information by issuing plural card numbers. CONSTITUTION: In case the card usage range of a mother card number is bigger than the card usage range of a child card number, a credit card management apparatus updates the card usage range of the mother card number and the child card number by reflecting an approval determination result(325, 330). In case the residual card usage range of the child card number is exhausted, the credit card management apparatus terminates the usage of the child card abidingly(340). |
