Detailed description:

1. Classification of overdue credit cards: banks classify overdue credit cards according to customers' repayment situation, which is usually divided into one to five levels, with five being the most serious classification.

2. Overdue time: 100 days. Overdue means that the borrower continuously delays repayment for more than 100 days.

3. Five-level classification: Five-level classification is mainly applicable to loan products that are seriously overdue, that is, the loan risk is extremely high and the recovery probability is extremely low. This classification usually means that the borrower's repayment ability is very weak, and stricter collection measures may be needed to recover the arrears.

4. Influencing factors: the classification of overdue grades usually depends on many factors, including overdue time, overdue amount, customer credit history, repayment willingness, etc. The longer the overdue time, the greater the overdue amount and the worse the past repayment record, which will lead to an increase in overdue grade.

5. Consequence: For borrowers, the overdue five-level classification will damage their credit records and further affect their ability to obtain loans and credit cards in the future. At the same time, banks can take legal measures or entrust third-party institutions to collect money and recover outstanding debts.

Summary:

Credit card overdue 100 days belongs to the five-level classification, which means serious overdue and extremely high risk. This classification will have a negative impact on the borrower's credit record and may lead to legal collection measures. The classification of overdue grades is usually based on factors such as overdue time, overdue amount, customer credit history and repayment willingness.
