1. Credit card extension means that when the cardholder uses the credit card installment function, he can't return the corresponding money according to the agreed time, and the cardholder can contact the credit card center to request an extension of the installment number. This situation is called credit card installment extension.

2. At present, many banks such as ICBC and Agricultural Bank of China have applied for credit card deferred repayment. The number of extension periods that ICBC can choose is the same as the first period, which is divided into three periods, six periods, nine periods, 12 period, 18 period and 24 periods, but the rate of each period is higher than the first period. If the first installment rate of Phase III is 1. 12%, the deferred installment rate is1.65%; The interest rate of the first installment of the sixth installment is 1.96%, and the interest rate of the deferred installment is as high as 3.60%. If the cardholder applies for an extension after the first repayment, the extension fee shall be calculated according to the unpaid principal.

3. The extension business of ABC is similar to that of ICBC. Cardholders can also apply for extension of outstanding principal after the first installment, but the cumulative number of installments before and after the first installment shall not exceed 24. No matter the initial payment or subsequent extension, the handling fee rate of each payment is six thousandths, which is more beneficial to cardholders.
