1 CCB's transaction was rejected because the balance of the user's CCB account was insufficient, which would directly lead to payment failure. After all, the account balance is not enough to complete the payment.

Cardo of China Construction Bank belongs to chip card or magnetic stripe card. If the chip or magnetic stripe of the chip card or magnetic stripe card is damaged, that is, it will be demagnetized, which will lead to the user being unable to be recognized when swiping the card with the Construction Bank Card, resulting in the bank transaction being rejected.

3 The freezing of the construction bank card will also lead to the rejection of the transaction. There are many reasons why bank cards are frozen, such as loss of bank cards, loss of users' reports, bank cards being frozen due to continuous input errors of bank card passwords, and freezing due to judicial reasons. This situation can only be restored after thawing.

When the transaction of CCB is rejected, we must contact the official customer service of CCB in time to consult the specific reasons, so as to find a solution and restore the normal use of CCB bank cards.

If the bank refuses to trade, it shall consult to understand the relevant reasons and apply for recovery after solving the problem. When a bank refuses a transaction during the transaction, it is necessary to first find out the reason for the refusal, perhaps because the amount of the transaction exceeds the remaining amount in the bank card of the party concerned. If the transaction fails due to insufficient balance, the transaction can only be resumed if the balance is sufficient. The reason why the transaction is rejected, as long as the following circumstances exist:

1, credit card with bad transaction record. The card used by consumers for payment has bad transaction records, such as refusal to pay.

2. Unauthorized transactions. The card the consumer used to pay was a 3D card, but the 3D verification code was not filled in during the payment process. Therefore, the system will judge the transaction as unauthorized and refuse to deduct money. In addition, it is also possible that the issuing bank of the consumer has not authorized the transaction.

3, the same IP in a short time, repeated payment for many times. Consumers pay repeatedly on the same IP in a short period of time, and there are other illegal acts such as cashing, money laundering and fraud. The system refused to deduct money.
