Three Domain Secure (3-D Secure)
Visa is announcing a global plan to support 3-D Secure 2.0 to help protect e-commerce transactions.
3-D Secure (3DS) – stands for Three-Domain Secure. A messaging protocol to enable consumers to authenticate themselves with their card issuer when making card-not-present (CNP) e-commerce purchases. 3DS is an additional security layer that will help prevent unauthorized CNP transactions and protects the merchant from CNP exposure to fraud.
The three domains consist of:
The merchant/acquirer domain
Issuer domain
the interoperability domain (payment systems)
The purpose of the 3DS protocol within the payments community is to facilitate the exchange of data between the merchant, cardholder and card issuer. The objective is to benefit each of these parties by providing the ability to authenticate cardholders during a CNP e-commerce purchase, reducing fraud.
Visa currently offers its 3-D Secure service through the Verified by Visa program, which supports the existing 3-D Secure 1.0 specifications for consumer authentication.
Visa anticipates that early adoption of 3-D Secure 2.0 will begin in the second half of 2017.
Merchants that authenticate transactions using 3-D Secure are generally protected from issuer card-not-present fraud-related chargeback claims,1 and this rule will extend to merchant-attempted 3-D Secure 2.0 transactions after 12 April 2019, the global program activation date.
