The repayment date of China Bank's credit card is 20 days after the bill date. The shortest interest-free period is 20 days and the longest is 50 days.

The interest-free period of credit card refers to the non-cash transaction of credit card, and the interest-free repayment period is from the bank bookkeeping date to the due repayment date. During this period, as long as the current payable amount (total amount owed) on the current statement is fully paid off, there is no need to pay any interest on non-cash transactions (advance cash does not enjoy interest-free discount).

Generally, you can enjoy the longest interest-free period by swiping your card on the second day of the billing date. The interest-free period enjoyed by swiping the card on the day of billing is the shortest.
