hello, you can enjoy the interest-free period when you swipe your credit card. The interest-free period means that you don't have to pay any interest if you pay off all the consumption money before the final repayment date. The interest-free repayment period is 2 days to 5 days, and the length of time will depend on the specific time of your consumption. If your consumption is before the current billing date, it will be included in the current bill; If it is included in the next bill after the billing date, you can enjoy a longer interest-free period.
