The common reasons for failure are as follows:

1. Information entered incorrectly
   
   • Verify that your card number, date, and CVV are entered correctly.
   • Billing address does not match the address registered with your card-issuing bank.
   • Cardholder name does not match.
2. Insufficient balance
   
   • Ensure that your balance or credit is sufficient to cover the total amount of this order.
3. PC interception
   
   • When entering your credit card information on a PC, the payment system checks if your transaction is secure. If it's deemed unsafe, the payment will be intercepted, leading to a failed transaction. It is recommended to complete the payment using a mobile device.
4. 3D verification failure
   

   • The credit card is not enrolled in the '3D Secure' service.

   • Incorrect 3D Secure password for the credit card.

   • The card-issuing bank is not part of the 3D Secure system

   • Busy systems at the card-issuing bank or network congestion, leading to extended wait times for processing transactions.

   • The bank or credit card organization determines the browser as unsupported.

5. High Risk Controlled
   
   • Credit card security is insufficient, please enable 3D Secure verification
   • The country of credit card issuance does not match the country of use
   • The region of the IP address does not match the shipping address.

3D Secure is an online security authentication service jointly promoted by international credit card organizations (Visa, MasterCard, JCB, etc.), card-issuing banks, and acquiring banks to prevent cardholders from being defrauded during online payments.

3D Secure is divided into two verification modes:

1. Static password verification: Cardholders need to apply to the card-issuing bank.

2. Dynamic password verification: The mobile phone number provided when applying for the credit card.
