Why use EMV 3DS?

Online merchants and their customers expect a secure, quick, and convenient eCommerce check out experience.

EMV 3DS provides an additional layer of security for eCommerce transactions and allows the card issuer to authenticate the cardholder through a dedicated and secure channel. It reduces cart abandonment and enables an effortless checkout experience for your customer. It replaces what was formerly known as 3DS 1.

How does it work?

Using merchant plug-in (MPI) software installed on your web server or the hosted services of your payment gateway, EMV 3DS works with Visa and MasterCard’s authentication services, Visa Secure (formerly known as Verified by Visa) and MasterCard® Identity Check (formerly known as SecureCode™). EMV 3DS provides transaction information to the card issuer to authenticate the transaction.

Not all transactions will need a verification check. In fact, depending on your business type, most will pass through without a challenge.

For EMV 3DS to be active, the cardholder must be registered through their issuing bank and the merchant through their financial institution.

Manage your risk

Stay vigilant when it comes to high risk or suspicious sales and remember to cancel and refund any order that seems suspicious.
