What Is 3D Secure

3D Secure, such as Verified by Visa and MasterCard SecureCode, allows transactions to be conducted in safety online, greatly reducing the risk of fraud and chargebacks. The process allows the cardholder domain, interoperability domain and merchant domain (3 Domains or 3D) to securely communicate with each other and allow the authentication of the cardholder transaction.

How Does 3D Secure Work

  • Enrolment Enquiry

    When a payment request arrives at the merchant or payment gateway, the Merchant Plug In (MPI) component is activated. The MPI talks to Payment scheme (Visa or MasterCard) to check if the card is enrolled for 3D Secure.

  • End User Identification

    If the card is not enrolled, this means that either the bank that issued the card is not yet supporting 3D Secure or it means that the cardholder has not yet been registered for the service. If however the card is enrolled, the MPI will redirect the cardholder to the 3D Secure authentication web page for the issuing bank; the cardholder will then identify himself.

  • Transaction Authorisation

    The MPI will evaluate the reply from the bank and, if successful, allow the transaction to proceed for authorisation. The transaction could still fail for lack of funds or other reasons but is more likely to be approved because of the authentication.
