Understanding 3D Secure and Its Role in Online Payments

Illustration of three interconnected domains representing 3D Secure3D Secure is a security measure that introduces an extra layer of protection for online transactions, guaranteeing that only authenticated users can complete a purchase.

In essence, it involves three domains working together to authenticate transactions: the acquirer domain (merchant), the issuer domain (card issuer), and the interconnection domain (payment processor).

This protocol aims to reduce fraud and protect both merchants and customers from unauthorized transactions.

The Three Domain Model Explained

The three-domain model consists of the acquirer domain (merchant), the issuer domain (card issuer), and the interconnection domain (payment processor), which collaborate to authenticate transactions. In this interoperability domain, the acquirer domain verifies the information supplied by the customer during authentication, ensuring the security of debit card transactions.

On the other hand, the issuer domain, which is associated with the cardholder’s bank, facilitates the enrollment of cards for the 3D Secure service and authenticates cardholders during the process.

Visa Secure and Mastercard SecureCode

Visa Secure and Mastercard SecureCode are examples of 3D Secure implementations that provide enhanced security for online credit or debit card transactions. These implementations have varying processes for generating one-time codes. Specifically, Visa Secure utilizes a one-time password, while Mastercard SecureCode utilizes a one-time code transmitted to your mobile phone through SMS, avoiding the use of static passwords.

These implementations, which add an extra layer of security through the use of an access control server, aid in protecting online card transactions from illegal use and acquisition.

The Inner Workings of 3D Secure Authentication

Illustration of data points and risk analysis for 3D Secure authenticationThe 3D Secure authentication process, also known as the financial authorization process, relies on data points and risk analysis to determine whether additional verification, such as biometric or two-factor authentication, is necessary during the payment process. This enhances the security of online transactions while ensuring a seamless experience for the customer.

We will examine the data points and risk analysis, along with biometric and two-factor authentication, in the context of this process.

Data Points and Risk Analysis

3D Secure collects and analyzes over 150 data points, including:

  • Device information
  • Order history
  • IP address
  • Location data
  • Transaction amount
  • Cardholder name
  • Card expiration date
  • Card verification value (CVV)

Through the use of Risk-Based Authentication (RBA), 3D Secure can evaluate each transaction’s fraud risk in real-time, making transaction reviews more accurate and lessening the chances of false positives or negatives.

This real-time data analysis enables low-risk transactions to be authenticated in the background, while higher-risk transactions may require additional verification steps.

Biometric and Two Factor Authentication

Biometric, two-factor, and password authentication methods, such as:

  • Fingerprint recognition
  • Facial recognition
  • Voice recognition
  • Iris scans
  • SMS codes

Biometric authentication, as a form of strong customer authentication, can be used to enhance the security of 3D Secure transactions. It relies on unique physical or behavioral characteristics to verify a user’s identity during a transaction.

Two-factor authentication (2FA) adds another layer of verification by requiring both card details and an additional authentication factor, such as a one-time password (OTP) sent to the user’s mobile device. Including these extra security measures allows 3D Secure to provide enhanced protection for customers and merchants against unauthorized access and fraudulent transactions.

The Advantages of Implementing 3D Secure for Merchants

Illustration of a secure online payment process with 3D SecureImplementing 3D Secure for your business brings numerous benefits, including:

  • Liability shift protection against fraudulent chargebacks
  • Improved customer experience with frictionless flow
  • Strengthening customer trust in online payments
  • Lowering fraud risk

Adding this extra security layer enables merchants to enhance their payment process and protect against potential fraud.

Liability Shift and Fraudulent Chargebacks

One of the primary advantages of 3D Secure for merchants is the liability shift, which transfers responsibility for fraudulent chargebacks to the card issuer and thereby protects merchants. This shift occurs when the customer successfully completes the 3D Secure authentication process, or when the merchant initiates a transaction with 3D Secure and subsequent transactions without it.

Implementing 3D Secure allows merchants to minimize fraud risk and shield their business from liability in case of incorrect customer authentication.

Frictionless Flow and Customer Experience

Frictionless flow in 3D Secure provides a smooth payment experience, leading to a decrease in customer abandonment and a rise in conversion rates. Utilizing risk-based assessments and exchanging background information, 3D Secure can assess each transaction’s risk and automatically approve those with low risk, offering customers a seamless experience.

This seamless and uninterrupted flow from the start to the completion of the shopping process leads to higher customer satisfaction and loyalty.

The Consumer Perspective: How 3D Secure Affects Online Shoppers

Illustration of mobile payments and 3D Secure authenticationWhile 3D Secure offers significant benefits in terms of security, it may also present some challenges for consumers. For instance, they may encounter compatibility issues with mobile payments and concerns about transaction abandonment due to additional authentication steps.

Understanding these challenges can help merchants address them and provide a better experience for their customers.

Mobile Payments and 3D Secure

As mobile payments become increasingly popular, accommodating 3D Secure authentication in this context may require additional steps or adjustments. To enable 3D Secure authentication for mobile payments, merchants must:

  1. Ensure their mobile payment platform supports 3D Secure.
  2. Implement the necessary software or API integration.
  3. Modify the mobile payment flow to include the extra verification step of 3D Secure.

Addressing these challenges enables merchants to offer a secure and easy payment experience to their customers, including on mobile devices.

Transaction Abandonment Concerns

Some customers may abandon transactions due to the extra authentication steps required by 3D Secure, leading to potential lost sales for merchants. Research indicates that transaction abandonment rate during 3D Secure ranges from 17-20%, with failure rates on transactions challenged through 3DS V2 estimated to be around 26%.

However, the implementation of a risk-based approach by card schemes has resulted in a 70% decrease in abandonment rates in UK transactions. Understanding and addressing these concerns can help merchants enhance the online shopping experience for their customers and reduce transaction abandonment.

While the United Kingdom has seen a significant decrease in abandonment rates due to the implementation of risk-based approaches, the situation varies across other European countries. The transaction abandonment rates during 3D Secure authentication in other European/EU countries also depend on the specific implementation of 3D Secure and the familiarity of consumers with this additional security measure.

For instance, countries like Germany and France, which have a high prevalence of online shopping, have reported lower abandonment rates due to increased consumer familiarity with 3D Secure. However, in countries where online shopping and the use of 3D Secure are less prevalent, higher abandonment rates may be observed.

It's important for merchants to understand these regional differences and adapt their 3D Secure strategies accordingly to minimize transaction abandonment and enhance the online shopping experience for their customers.

Setting Up 3D Secure for Your Business

Illustration of setting up 3D Secure for business with payment processorsSetting up 3D Secure for your business involves partnering with payment processors and tailoring the authentication process to your needs. Payment processors, such as Mollie, Stripe or Adyen, can help you implement 3D Secure and ensure compliance with relevant regulations.

Partnering with Payment Processors

Partnering with payment processors like Mollie or Adyen can help businesses implement 3D Secure and ensure compliance with relevant regulations. Most payment processors offer 3D Secure as a feature of their payment gateway solutions, and merchants are advised to work with their payment processor to enable and configure 3D Secure for their online store. This may involve setting up the necessary API integration, configuring the authentication flow, and implementing the required changes in the checkout process. It is recommended to refer to the documentation and support resources provided by the payment processor for detailed instructions on integrating 3D Secure.

Customizing the Authentication Process

By customizing the 3D Secure authentication process, merchants can strike a balance between security and convenience for their customers. Custom Radar rules provide businesses with the ability to determine when to request 3D Secure and how to manage each authentication result and liability shift.

Merchants can also utilize the tools offered by payment gateways for online transaction security, allowing them to include extra security measures and tailor the 3DS process to their specific needs.

Navigating 3D Secure Challenges and Errors

Dealing with 3D Secure challenges and errors requires an understanding of when 3D Secure fails and strategies for rectifying these problems. In the event that a card does not support 3DS or an error occurs during the authentication process, the payment will continue as normal, but the issuer will not be held liable, as a successful 3DS authentication did not take place.

When 3D Secure Fails

If 3D Secure authentication fails, customers should contact their card issuer and merchants should check for potential issues with their 3D Secure implementation. Typical causes of 3D Secure authentication failure include entering incorrect cardholder information and not authenticating with the correct password or code.

If 3D Secure authentication fails, merchants need to decide whether to continue with the transaction.
