As far as I know, the reasons for unsuccessful credit card applications are generally as follows:

1. The bank cannot confirm whether my signature or the signature of the application form is inconsistent with the certificate;

2. The signature of the application form is inconsistent with the regulations or the application form has been signed but not signed.

.3. The application is that the information is not detailed, the family is unknown or not provided, the salary unit information is unknown or not provided, and the contact information is unknown or not provided.

4. The applicant's relevant information is insufficient or not filled in on time, or the applicant's age does not meet the requirements;

5. The applicant's unit does not meet the requirements of the bank or the post does not meet the requirements;

6. The applicant does not have a job or a stable source of income, and it is also possible that the applicant is a practitioner in a restricted application industry.

It is suggested that the landlord combine his own reality to see if there are any problems with the above items. I hope my answer can help the landlord!
