As far as I know, there are four main reasons why credit cards are rejected. Of course, I don't know four reasons. More landlords can call the customer service of the bank you apply for directly. Generally speaking, the common reasons are:

First, the application information is incomplete; The applicant fails to provide the basic documents; The documents provided by the applicant do not meet the acceptance criteria.

Second, your industry does not meet the credit card application; Or age, working years, salary income or other financial conditions do not meet the prescribed card issuing standards.

Third, you have a record of malicious overdraft or loan default in other banks before, or a record of unpaid telephone bills, and so on.

Fourth, you have repeatedly applied, and the cycle interval is too short.

Mainly the above, the landlord can judge what caused his application to be unsuccessful according to his actual situation. I hope my answer can help the landlord!
