Credit card repayment must first bind my debit card, and then deposit the corresponding amount into the debit card before the repayment date. After the debit card is bound, the specific credit card repayment method and term are as follows: 1. If it is paid off in full, no cost will be incurred; 2. Credit cards generally have a grace period of three days after the repayment date, and repayment within the grace period is regarded as timely repayment; 3. To repay the minimum repayment amount, you need to calculate the daily interest, starting from the consumption bookkeeping date.
