The reason why a credit card transaction is rejected is as long as the following conditions exist:

1. Credit card with bad transaction record. The card used by consumers to pay has bad transaction records, such as chargebacks, etc.

2. Unauthorized transaction. The card used by the consumer to pay was a 3D card, but the 3D verification code was not filled in during the payment process. Therefore, the system will judge it as an unauthorized transaction and refuse to deduct the money. It is also possible that the consumer's card-issuing bank did not authorize the transaction.

3. The same IP is paid multiple times within a short period of time. Consumers who pay multiple times for the same IP within a short period of time are suspected of cashing out, money laundering, fraud and other illegal activities. The system refuses the deduction.

4. The card balance is insufficient or the card validity period has expired. The card used by the consumer to pay exceeds his credit limit or the card has expired.

5. The information is incomplete, wrong or the payment is terminated midway. When consumers fill in credit card-related information, if the information is incomplete or incorrect, the bank will be unable or refuse to deduct the money.

6. Payment in risk areas. The IP that consumers pay comes from areas classified as high-risk by international credit card organizations. The system will judge high-risk transactions and refuse to charge. Such as: Venezuela

7, cross-border, cross-regional transaction payment. The card used by the consumer to pay is a card from a non-resident country, and there is suspicion of card theft, so the system will rate the transaction as a high analysis transaction and refuse to deduct the money.
