1. Overdue online loans are usually not directly related to credit card applications: credit cards and online loans are two different financial products, and they have independent application and approval processes. When banks decide whether to approve a credit card application, the main factors they consider include the applicant's credit history, income, etc., rather than a specific overdue loan record.

2. Credit card applications pay more attention to other factors: Credit card issuers usually focus on factors such as the applicant’s credit score, income stability, and repayment ability. While a past due date may have some impact on your credit score, it's usually not the deciding factor.

3. Overdue online loans have a greater impact on your credit record: Although overdue online loans will not directly affect your credit card application, it will have a negative impact on your credit record. Overdue records can cause a decrease in your credit score and adversely affect future borrowing applications.

To sum up, overdue online loans will not directly affect your application for a credit card. However, overdue records may have a negative impact on your credit score and credit history, so it is recommended that you try to pay off your debts on time and maintain a good credit record.

Therefore, paying off debts on time and avoiding overdue payments is crucial to maintaining a good credit history.
