Online payment security has become a critical concern for ecommerce businesses. As more customers purchase products online, Magento 2 merchants need a payment gateway that not only processes transactions reliably but also provides strong protection against fraudulent payments.
For Australian businesses, NAB Transact provides a secure online payment solution that supports modern payment authentication technologies, including EMV 3D Secure (3DS2).
When integrated with Magento 2, NAB Transact with 3D Secure helps merchants create a safer checkout experience by adding an additional layer of customer authentication while reducing the risk of unauthorised transactions.
This article explains how NAB Transact 3D Secure Magento 2 integration works, why EMV 3DS is important for online payments, and how it improves payment security for Magento stores.
What is EMV 3D Secure?
EMV 3D Secure (3DS) is a payment authentication standard designed to improve security for online card transactions.
Traditional online payments mainly rely on card details entered by customers. However, if card information is stolen, attackers may attempt to perform fraudulent transactions.
3D Secure introduces an additional verification step between the customer, the card issuer, and the payment gateway.
Depending on the transaction risk level, customers may be required to complete additional authentication, such as:
- Confirming the payment through a banking application
- Entering a verification code
- Approving the transaction through the card issuer
- Completing another authentication method provided by the bank
The purpose of EMV 3DS is to verify that the person making the payment is the legitimate cardholder.
How Does NAB Transact 3D Secure Work with Magento 2?
A Magento 2 store integrated with NAB Transact can use EMV 3D Secure authentication during the payment process.
The typical payment flow works as follows:
Customer Checkout
↓
Magento 2 Payment Gateway
↓
NAB Transact
↓
EMV 3D Secure Authentication
↓
Card Issuer Verification
↓
Payment Approval
The process includes several steps:
Customer starts checkout
The customer selects the payment method and enters card details during the Magento 2 checkout process.
Magento 2 sends the payment request
Magento 2 securely communicates with NAB Transact through the payment gateway integration.
NAB Transact performs risk evaluation
The transaction is analysed to determine whether additional authentication is required.
Low-risk transactions may be processed smoothly, while higher-risk transactions may require customer verification.
Customer completes authentication
If required, the customer completes verification through their card issuer.
Payment is processed
After successful authentication, NAB Transact completes the transaction and returns the payment result to Magento 2.
Benefits of NAB Transact 3D Secure for Magento 2 Merchants
Reduce fraudulent transactions
Payment fraud is one of the biggest challenges for online retailers. Stolen card information can be used to create unauthorised purchases, causing financial losses and customer disputes.
EMV 3D Secure adds another verification layer to help confirm customer identity before payment approval.
Improve customer trust during checkout
Customers are increasingly concerned about payment security when shopping online.
A Magento 2 store that uses a payment gateway with 3D Secure authentication provides customers with greater confidence when entering their payment information.
Provide a better checkout experience with 3DS2
Modern EMV 3D Secure v2 is designed to reduce unnecessary checkout interruptions.
Instead of requiring authentication for every transaction, 3DS2 uses risk-based authentication to determine when additional verification is needed.
This helps merchants balance:
- Payment security
- Fraud prevention
- Smooth customer checkout experience
EMV 3D Secure v2 for Modern Magento 2 Payments
EMV 3D Secure v2 (3DS2) improves the traditional 3D Secure experience by supporting more advanced transaction analysis and better compatibility with modern ecommerce environments.
Key improvements include:
- Risk-based authentication
- Improved support for mobile shopping experiences

For Magento 2 merchants, 3DS2 provides a more balanced approach between protecting payments and maintaining a fast checkout process.
