The reasons for failure of credit card application may be as follows:

1. Not meeting the card issuance conditions. To apply for a credit card, you need to be over 18 years old; have good credit information and no bad records; have a fixed job; and have stable economic income.

2. The application materials are incomplete. The application materials provided need to ensure the authenticity and completeness of the content. If the information is fictitious or incomplete, the bank will not approve the application.

3. Bad credit record. The applicant's credit information affects credit card processing. Please see the central bank for specific credit information.

4. Submit applications frequently. Some banks will consider applicants who frequently apply for multiple credit cards in a short period of time to be high risk, but not all banks are like this.

5. There are problems with the applicant organization. Card applicants must apply for a credit card at an official institution or a third party authorized by an official institution, otherwise there may be a risk of personal information being leaked.
