There is no necessary connection between credit card application and the purchase of financial management, so it is normal to be rejected. Because whether a bank approves a credit card application is determined by many factors.
There are three reasons why a credit card is rejected:
The first is that there are problems with the applicant’s card application information, such as under 18 years of age, occupation that is prohibited for bank credit cards, insufficient information provided, and salary slips. The information is not detailed and so on.
Secondly, it may be that the applicant’s credit report is poor, such as the applicant applying repeatedly, having an unstable job, having a bad credit record, or being unable to be contacted, etc.
The third category is other reasons, such as the contact person not knowing or unwilling to be the contact person, the applicant's health reasons, the contact person not meeting the requirements, etc. You can check the reason yourself first.
