Why does 3DS reduce conversion?

3DS introduces additional steps in the checkout flow, which can create friction and lead to customer drop-off. Applying authentication unnecessarily can negatively impact conversion rates.

Dynamic 3DS applies authentication selectively based on transaction context, such as risk level, customer behavior, or regulatory requirements. This helps balance fraud prevention with conversion.

What is step-up authentication?

Step-up authentication is when 3DS is triggered after an initial transaction attempt, typically in response to an issuer requirement. This allows merchants to retry and recover payments that would otherwise be declined.

Is 3DS required for SCA compliance?

In regions like the European Economic Area, Strong Customer Authentication (SCA) regulations require 3DS or similar methods for certain transactions. However, exemptions can apply depending on risk and transaction type.

Can 3DS be used across multiple PSPs?

Yes. Payrails allows merchants to apply a consistent 3DS strategy across multiple payment providers, rather than relying on each PSP's individual implementation.

How does 3DS help reduce fraud?

3DS verifies the identity of the cardholder during checkout, reducing unauthorized transactions and shifting liability to the issuing bank in many cases.

How long does it take to implement 3DS?

Implementation typically depends on the payment setup and integration complexity. With Payrails, 3DS can be configured within existing payment workflows without building custom authentication logic.

3D Secure (3DS) authentication for enterprise merchants

Get authentication right on every transaction

3DS is often applied too broadly, creating unnecessary friction, or too narrowly, increasing risk and declines. Payrails integrates authentication into the payment flow so it can be applied dynamically, and measured, to improve outcomes based on real performance, not assumptions.

Apply 3DS dynamically

Most 3DS implementations rely on fixed logic or default PSP behavior. Payrails applies authentication dynamically based on transaction context, risk signals, and regional requirements — reducing unnecessary challenges while staying SCA-compliant across markets.

Recover payments with step-up authentication

When issuers require authentication (for example due to SCA), Payrails can trigger 3DS during a retry flow. This "step-up" approach recovers transactions that would otherwise be declined.

PSP-agnostic 3DS strategy

Payrails' provider-agnostic platform enables one unified 3DS strategy across multiple PSPs — avoiding inconsistencies between providers and giving you control over when and how 3DS applies in every market.

3D Secure is an authentication protocol used to verify cardholder identity during online payments. It adds an extra step, such as a one-time password or biometric check, to reduce fraud and shift liability to the issuer. The current version, 3DS2 (EMV 3DS), sends more transaction data to the issuer, so many low-risk payments are approved without any challenge to the customer.
