In order to prevent borrowers from using loan funds in places prohibited by banks and the state, many banks require borrowers to upload use certificates from time to time. These vouchers can prove the borrower's specific consumption field, and can judge the relevant situation according to the time and amount. If the bank financial institution requires the borrower to provide the certificate of use, it must try its best to meet it, otherwise it may be required to settle in advance and the loan amount will be recovered.
