For revolving loans, banks generally don't check the credit information every time, but they will grant credit and adjust the loan interest rate according to the borrower's repayment record and credit rating. If the borrower has bad records such as overdue and arrears, it will affect the trust in the bank and lead to the reduction or cancellation of the credit line. Therefore, timely repayment and maintaining a good credit record are the keys to the success of revolving loans.
