1. Credit card interest-free overdraft has a time limit, and the time limit of each bank is different. The general bank will tell you the latest repayment date of the current period, that is, the billing date.

2. On the billing date, the bank will clearly list your consumption record, the amount to be repaid, the minimum repayment amount and the latest repayment date between the previous billing date (last month) and the billing date of this month on the credit card bill.

There are two kinds of bills: paper and electronic. At present, most banks encourage customers to use electronic bills.

You need to pay off the overdraft amount according to the repayment amount (or the minimum repayment amount) on the bill.
