Consequences of overdue repayment of credit cards:
1. It is a breach of contract not to repay after the credit card is overdrawn. The bank may require the cardholder to repay the principal, overdue interest, late payment fee and over-limit fee, etc. If the bank sues the court and wins, the cardholder will also bear the litigation costs.
2. If the cardholder maliciously overdraws a certain amount for the purpose of illegal possession and fails to pay it back within the time limit, which constitutes the crime of credit card fraud, he shall also bear criminal responsibility.
3. Overdue repayment will leave a bad credit record for the cardholder and affect the smooth progress of the cardholder's future loan.
