Credit card 3D authentication:

In order to improve the security of online transactions and effectively reduce the occurrence of online fraudulent transactions, VISA established the 3DSecure specification (ThreeDomainSecure, referred to as 3D), and later Mastercard and JCB also* **Also join this specification. 3D is only applicable to MOTO (mailordertelephoneorder) transactions occurring at overseas online merchants. When making transactions, cardholders only need to enter the card number, validity period, CVV2, dynamic password and mobile phone verification code on the merchant's webpage to complete the transaction. There is no need to go through online banking or other third-party payment platforms to enhance transaction security.

Warm reminder:

1. 3D authentication is the online payment method of each card organization. The information entered during the transaction is determined by each card organization and will be different. If you need to enter a mobile transaction code, use the mobile phone number you reserved in the bank card system when you applied for a credit card.

2. The supplementary card of a credit card that supports 3D authentication service can also activate 3D authentication service, but this supplementary card must have independent online banking.
