3D Secure (3-domain structure), also known as a payer authentication, is a security protocol that helps to prevent fraud in online credit and debit card transactions. This additional security was initiated and created by Visa and MasterCard and it’s branded as ‘Verified by Visa’ and ‘MasterCard SecureCode’ respectively.
The payer authentication is a three-part process, so there are three parties involved in the process: the issuer (such as Visa or MasterCard), the acquirer, and the interoperability domain (such as payment system).
How 3D Secure works
- The customer enters their credit or debit card information in the payment form
- Our payment service contacts a directory server and gets the message that the card is registered in the program
- The customer sees the 3D Secure page when they need to authenticate themselves to the issuing bank by entering the password or a one time PIN
- The result of the 3D Secure authentication goes to our payment service and then we submit transaction details to the acquiring bank
- The transaction is authorised by the acquirer
- The customer can see the response about whether the transaction is successful or failed
Advantages of 3D Secure
One of the advantages of 3D Secure is that it reduces fraud. It also makes depositing safer online, and it is easy to use.
3D Secure has certain limitations: not all cards are currently participating in the program authentication payer scheme. PLease check with your bank for more information.
