1. Credit score: Late repayment will lower personal credit score, which may lead to rejection of credit card application or obtaining a lower credit limit.

2. High interest rates and fees: Credit card companies may think that loans overdue means that individuals can't repay on time, so they will charge high interest or extra fees to cardholders.

3. Limit line: Overdue records may cause credit card companies to limit your credit line and affect your ability to use credit cards in an emergency.

4. Credit review: overdue loans will leave a bad record in the credit report, and when applying for other loans or credit products in the future, they may be strictly reviewed or even rejected.

5. Increase the debt risk: If there are high overdue online loans and credit card overdrafts at the same time, individuals will face greater financial risks and may find it difficult to repay their debts.

Summary: The high overdue amount of online loans will have a negative impact on credit cards, including lower credit score, high interest rates and fees, limited credit line, stricter credit review and increased debt risk. Timely repayment of debts is an important factor to maintain a good credit record.
