The Worldwide Standard for Online Payment Authentication

What is 3D Secure?

3D Secure is a standard protocol in the payments industry that aims to detect and prevent credit card fraud, and in turn to protect credit card holders, merchants, and banks from security fraud. 3D Secure has been adopted by Visa, Mastercard, American Express, JCB, Discover, UnionPay, as well as many other regional card schemes. Recently, the advent of 3D Secure 2 (3DS2) has ushered in a new era for the protocol, with improvements to the accuracy of fraud detection, and much improved cardholder usability.

About 3D SECURE AUTHENTICATION

3D Secure is an authentication protocol for online credit card payments, and it has been the de facto authentication standard since the year 2000. A recent revision to the protocol has produced "3D Secure 2”, which includes many added features and benefits over 3DS1. But while the industry is gradually transitioning from 3DS1 towards its successor, 3DS1 still remains the most widely adopted authentication protocol for eCommerce transactions. 3D Secure was designed by Visa in 1999, and has since been adopted by other card schemes. You may have used 3D Secure before when asked to type in a password during eCommerce checkout, or you may recognise the protocol by its various market branded names.

3D Secure

3DS1 has been widely deployed in all countries around the world, and has a long, proven record of solving credit card fraud issues for merchants, payment gateways, and banks alike.

How it Works

The capital "D" in "3D Secure" stands for "domain", and there are 3 of them: the acquiring domain, the issuing domain, as well as the interoperability domain to link the two together.

3D Secure workflow
Issuing Domain
Issuing Domain
ACCESS CONTROL SERVER (ACS)

The issuing domain is where the issuing banks operate. They are the ones who issue cards to cardholders, who then use the card to purchase goods and services. The issuing bank needs to deploy an Access Control Server, also known as "ACS", in order to receive 3D Secure messages, process the messages, and authenticate the card user.

Directory Server
Interoperability Domain
Directory Server

The interoperability domain consists of just the Directory Server, which is deployed by card schemes, and can be considered the glue between the acquiring and issuing domains. If a merchant wants to authenticate a credit card and its user, how do they know which issuing bank to contact? The answer is simple: they send a message to the card scheme's Directory Server, which holds a "directory" of all the BIN ranges corresponding issuing banks. The Directory Server will receive the message from the MPI, check the card number against the BIN range directory that it holds, and forward that message onto the correct issuing bank. The issuing bank would then proceed with authenticating the card user.

Merchant Domain
Acquiring Domain
MERCHANT PLUG-IN (MPI)

The acquiring domain is where the merchant, payment gateway, and acquiring banks sit. They initiate the transaction, which they wish to be authenticated. In order to do so, entities in the acquiring space need to deploy a "merchant plug-in", also known as "MPI".
