Too many credit card applications will affect loans. For example, users frequently apply for credit cards in a short period of time, so there will be a lot of inquiry records in the credit report. When applying for a loan, the lending institution will think that the user has applied for a large number of credit cards in a short time because of the shortage of funds, so it will refuse the user's loan application without ensuring whether the user has the repayment ability.

There are multiple credit cards at the same time, and the possibility of overdue will increase. Once there are too many overdue records, it will also affect the handling of various credit businesses in the future.
