Hello, the longest interest-free period for our credit card is 50 days. Assume that the billing date is the 10th and the due repayment date is the 28th: ??For example: Generally, the customer will be on August 9th. If the customer consumes on August 10, the bill will be issued on August 10, and repayment will be required on August 28, so the interest-free period is the shortest; if the customer consumes on August 10, the bill will not be issued until September 10, and September If you repay on the 28th, there will be an interest-free period of up to 50 days. That is, if the customer repays the entire repayment amount before the due payment date (inclusive), the card consumption on the bill date can enjoy the longest interest-free period.
