1. First of all, overdue credit card repayment will have a negative impact on personal credit history. After the credit card is overdue for one week, the bank will submit the overdue record to the credit reporting agency, and then add the overdue information to the personal credit report. Overdue records will reduce the personal credit score and make the personal credit status decline.

2. Secondly, overdue will affect the increase of personal credit card limit. When deciding whether to increase the credit limit, banks will comprehensively consider the personal credit status, among which overdue records are an important factor for banks to consider. A week overdue will be regarded as a credit defect, which may lead to the failure to increase the application amount and limit the use of personal credit cards.

3. In addition, overdue credit card repayment will lead to penalty interest and liquidated damages. Once overdue, the bank will calculate the penalty interest according to the number of overdue days, and the longer the overdue time, the higher the penalty interest will be. At the same time, banks will also charge corresponding liquidated damages, further increasing the repayment pressure of individuals.

to sum up, one week overdue credit card will have a negative impact on personal credit record and credit card limit, and lead to penalty interest and liquidated damages. Therefore, users are advised to check the credit big data regularly to understand their credit status, and ensure repayment on time to avoid overdue situations.

Extended data:

Credit big data refers to the collection, collation and analysis of personal credit-related data through big data technology and methods, including personal repayment records, overdue conditions, loan history, etc. Credit big data can help banks and financial institutions to evaluate personal credit status more accurately and provide better financial services for individuals.

By querying credit big data, individuals can know their credit scores and credit records, find and correct wrong information in time, and take measures to improve their credit status according to their own situation. At the same time, banks can also assess personal credit risk through credit big data and formulate financial products and services more accurately.

At present, there are many credit reporting agencies providing credit reporting and credit inquiry services, such as China People's Bank Credit Information Center and China Credit Report. Users can check their personal credit reports online by logging on to the official websites of relevant credit reporting agencies, understand their credit status, and take corresponding measures as needed.

In short, a credit card overdue for one week will adversely affect the credit history, credit card limit and personal economy. Users are advised to develop good repayment habits, check credit big data regularly, understand and manage personal credit status in time, ensure good credit and obtain better financial services.
