the principle of credit card waiver is that credit card issuers provide customers with a certain loan amount and a consumption freeze period according to their income, credit records and other conditions, and customers should pay the total consumption within this period and pay off all debts within the timely repayment period. If the customer fails to repay the loan or fails to repay the loan, it will incur penalty interest and late payment fees. Credit card waiver means that the card issuer waives part or all of its penalty interest and late payment fees according to the specific situation of customers, so as to reduce the payment burden of customers and maintain a good credit record.
