Credit account integration method

摘要

A credit account management system comprises a refund method management unit, and a credit limit setting unit. The refund method management unit receives the designation of a refund method of the outstanding credit-loan amount in the credit account after integration from the user, and sets the refund method of the outstanding credit-loan amount in the credit account after integration. After credit accounts are integrated, the outstanding credit-loan amount is refunded according to the refund method set by the refund method management unit. The credit limit setting unit compares the outstanding credit-loan amount in the credit account after integration and a target credit limit which is expected to be given in the credit account after integration, and sets a credit limit in the credit account after integration based on the comparison result.
