Reducing Payment Declines with Smart 3DS Strategies

Online payments walk a fine line between security and convenience, especially when it comes to secure payment processing for high-risk industries. Push too hard on fraud prevention and you risk frustrating genuine customers. Make the checkout too frictionless and you expose your business to fraud, chargebacks and regulatory risk.

This is where Smart 3D Secure (3DS) comes in. When implemented correctly, Smart 3DS can reduce payment declines, increase approval rates and strengthen security, all without damaging the customer experience.

In this article, we’ll explain what Smart 3DS is, why it matters and how an optimised 3DS strategy helps businesses strike the right balance between frictionless authentication and fraud prevention.

What Is 3D Secure?

3D Secure is an authentication protocol designed to reduce card fraud during online transactions. It adds an extra layer of verification by asking the cardholder to confirm their identity, typically through their bank or issuing app.

The latest version, 3D Secure 2 (3DS2), was introduced to improve on earlier iterations by enabling better user experiences, mobile-first design and risk-based authentication.

But simply enabling 3DS isn’t enough. Poor implementation can lead to unnecessary challenges, higher abandonment rates and increased payment declines. That’s why Smart 3DS matters.

What Is Smart 3D Secure?

Smart 3DS is a data-driven, adaptive approach to authentication. Instead of applying 3D Secure to every transaction, Smart 3DS uses real-time risk analysis to decide when authentication is truly needed.

Low-risk transactions can pass through frictionless authentication, while higher-risk payments are dynamically routed through step-up verification. The result is a smoother checkout for legitimate customers and stronger protection against fraud.

At its core, Smart 3DS focuses on three things:

• Reducing unnecessary authentication challenges.
• Improving authorisation and approval rates.
• Maintaining compliance and fraud prevention standards.

Why Traditional 3DS Can Hurt Conversion

One key mistake businesses make is treating 3DS as a blanket security tool. When every transaction is challenged, even low-risk customers face extra steps that slow down checkout.

This can lead to:

• Higher cart abandonment.
• Increased payment declines due to failed authentication.
• Poor mobile checkout experiences.
• Lower lifetime value from frustrated customers.

In competitive e-commerce, platforms and subscription models, even a small increase in friction can significantly impact revenue.

How Smart 3DS Reduces Payment Declines

Payment declines don’t always happen because of insufficient funds or fraud. Many declines occur due to overly aggressive authentication or poor routing decisions.

Smart 3DS helps reduce declines by:

• Applying authentication when necessary.
• Leveraging issuer and network data to assess risk accurately.
• Supporting exemptions such as low-value transactions and trusted beneficiaries.
• Optimising the authentication flow for mobile and web.

By sending fewer low-risk transactions through step-up authentication, businesses see higher approval rates and fewer failed payments.

Frictionless Authentication: The User Experience Advantage

One of the biggest benefits of Smart 3DS is frictionless authentication. When a transaction is deemed low risk, the customer doesn’t see any additional steps, the payment simply goes through.

This improves:

• Checkout speed
• Customer satisfaction
• Conversion rates
• Repeat purchase behaviour

For returning customers and those using trusted devices, implementing frictionless authentication flows is essential. These strategies enable businesses to uphold security standards, even in high-risk sectors, without compromising the user's purchasing journey or the reliability of payment processing.

Smart 3DS and Fraud Prevention

Reducing friction doesn’t mean lowering security, especially when it comes to secure payment processing for high-risk industries such as iGaming. In fact, Smart 3DS often improves fraud prevention by focusing attention where it’s most needed.

High-risk transactions can still trigger:

• Strong Customer Authentication (SCA)
• Biometric verification
• One-time passcodes or in-app approvals

This targeted approach ensures that fraud controls are applied intelligently, rather than indiscriminately. It also reduces false positives, one of the biggest drivers of lost revenue in online payments.

The Role of Data and Payment Orchestration

Smart 3DS works best when combined with payment orchestration. By analysing transaction data across multiple parameters, such as location, device, behaviour and issuer response, businesses can make smarter authentication decisions in real time.

Payment orchestration enables:

• Dynamic 3DS routing by market, issuer or risk level.
• Intelligent retry logic for failed authentications.
• Centralised control over security rules and exemptions.

Together, Smart 3DS and orchestration give businesses flexibility, resilience and better performance across markets.

Why Smart 3DS Matters for Regulated and High-Risk Industries

For sectors like e-commerce, platforms, subscriptions and iGaming, the balance between security and conversion is especially critical. 

Businesses operating in regulated environments need to deliver fast and reliable payment experiences, especially with B2B payment services, all while maintaining compliance with Strong Customer Authentication (SCA) requirements.

Smart 3DS makes this possible by aiming to ensure authentication is applied where it adds value, not where it creates friction.

This leads to:

• Higher acceptance rates.
• Lower fraud and chargeback exposure.
• Better compliance outcomes
• Improved customer trust.

Reducing Payment Declines with Smarter 3DS Security

Smart 3D Secure isn’t about removing security. It’s about applying it intelligently. By balancing frictionless authentication with targeted fraud prevention, businesses can reduce payment declines, improve approval rates and protect both revenue and customers.
