The credit line is smaller than the credit line. For example, there are only 6,000 credit cards left in Xiao M, and the card holder needs to pay 6 100 yuan online. Naturally, his payment was unsuccessful. In this case, the cardholder can obtain more available credit card limit by repayment or applying for temporary limit.

In the process of credit card payment, entering incorrect credit card information including credit card number, payment password and verification code will lead to the failure of credit card online payment.

In order to control their credit card consumption, many card holders will set a payment limit for their credit cards. After that, the credit card consumption exceeds the payment limit, and the transaction will fail.
