Fraud Prevention Guide: 3-D Secure (3DS)
3-D Secure (3DS) authentication shifts fraud-related chargeback liability to the card-issuing bank, providing added protection for merchants. If the issuing bank flags a transaction as risky, a challenge flow is triggered to verify the cardholder’s identity. According to card brands, approximately 95% of 3D Secure transactions are completed frictionlessly.
What is 3-D Secure (3DS)?
3-D Secure (3DS) helps prevent online fraud with card-not-present transactions. When enabled, a cardholder is required to authenticate their identity before the transaction can be completed.
The three domains of 3-D Secure (3DS) represent the key stakeholders in the authentication process for online card payments:
Issuer Domain
The cardholder’s bank or financial institution responsible for verifying the cardholder’s identity during the transaction.
Acquirer Domain
The merchant’s bank or payment processor facilitating the transaction on behalf of the merchant.
Interoperability Domain
The infrastructure that connects the issuer and acquirer, typically managed by the card networks to enable secure communication and authentication.
How does 3DS work?
First, the cardholder enters their card information to complete payment.
- If the card-issuing bank deems the transaction is low-risk, they approve the transaction.
- If the card-issuing banks deems the transaction high-risk, they may request additional verification.
Verification methods vary by bank but are user friendly for genuine cardholders. Once the cardholder is authenticated, the bank approves the transaction.
According to card brands, approximately 95% of 3D Secure transactions are completed frictionlessly.
Where is 3DS available?
The Strong Customer Authentication regulation, as part of PSD2 in Europe and similar regulations in the UK, India, Japan, and Australia, might require using 3DS for card payments.
3DS is optional in other regions, like the United States, but it's highly advised for all merchants to enable 3DS as a tool to reduce fraud.
3DS is often recognized with branding of Visa (Verified by Visa), Mastercard (Secure Code), and American Express (SafeKey), Discover (ProtectBuy).
What are the benefits of 3DS?
3DS is a critical fraud prevention tool that helps verify cardholder identity during online payments, significantly reducing the risk of unauthorized transactions. Beyond added security, 3DS offers a liability shift for fraud-related chargebacks, protecting your business from financial losses.
