1. Billing date and repayment date of credit cards: The repayment date of credit cards is subject to your billing date. Usually, when you receive the first bank mail card, the billing date and repayment date will be written on the bill. Usually, banks will have an interest-free repayment period of several tens of days. The interest-free repayment period is the period from the billing date to the repayment date.

2. The difference between paying the current period, paying the full amount and paying the minimum repayment:

(1) Paying the principal: paying off all the amount of this bill and waiting for the rest to be paid in the next period;

(2) Pay all: Pay off all bills;

(3) Minimum repayment: credit will not be affected. According to the amount determined by your billing bank, about 1% of the amount in this bill will be repaid without affecting credit.

3. Repayment rules: bind a savings card that automatically repays when it expires or use a third party, such as Alipay and WeChat.

4. Remedy of bad credit: every bank's credit card has a grace period, and you can ask the customer service for the grace period according to each bank. If the credit card forgets to repay, or the repayment is overdue, you can talk to the customer service for less than three days, and try not to count it as credit.
