One of the solutions that has been developed to enhance online security is 3D Secure, a protocol that adds an extra layer of authentication for online card payments. In this article, we will explain what 3D Secure is, how it works, what are its benefits, and how you can implement it in your online business.
Introduction
What is 3D Secure and why is it important for online transactions?
3D Secure is a protocol that was created by Visa and Mastercard to provide an additional security layer for online credit and debit card transactions. The name refers to the "three domains" that interact using the protocol: the merchant/acquirer domain, the issuer domain, and the interoperability domain.
The main purpose of 3D Secure is to verify that the person making an online purchase is the legitimate owner of the card being used. This way, both customers and merchants are protected from unauthorized or fraudulent charges. The protocol also shifts the liability for chargebacks from the merchant to the card issuer, reducing losses and disputes for online businesses.
How does 3D Secure protect both customers and merchants from fraud?
When a customer makes an online purchase using a card that is enrolled in 3D Secure, they are asked to provide an additional proof of identity before completing the transaction. This proof can be a password, a code sent to their phone or email, or a biometric verification such as fingerprint or face recognition. This process ensures that only the authorized cardholder can use their card online.
If a fraudster tries to use a stolen card or card details on a website that supports 3D Secure, they will not be able to complete the payment without knowing or having access to the cardholder's verification method. This prevents them from making unauthorized purchases and reduces the risk of chargebacks for merchants.

Reduced fraud and chargebacks: By requiring an extra authentication step, 3D Secure reduces the chances of fraudulent transactions and chargebacks. This saves time, money, and reputation for online businesses.
Increased customer trust and loyalty: By providing a secure payment environment, 3D Secure increases customer confidence and satisfaction. Customers who feel safe shopping online are more likely to return and recommend the online business to their friends and family.
Improved conversion rates: By offering a fast and easy authentication process, 3D Secure reduces the friction and abandonment that customers may experience during checkout. Customers who complete their purchases without hassle are more likely to buy again and spend more.
How 3D Secure works
What are the three domains involved in 3D Secure authentication?
The three domains that interact using the 3D Secure protocol are:
The merchant/acquirer domain: This domain includes the online merchant, the payment gateway, and the acquirer (the bank that processes the payment on behalf of the merchant).
The issuer domain: This domain includes the card issuer (the bank that issued the card to the customer) and the card network (Visa, Mastercard, etc.).
The interoperability domain: This domain includes the infrastructure and services that enable the communication and coordination between the other two domains. This includes the 3D Secure server, which is responsible for initiating and verifying the authentication process.
What are the steps involved in a typical 3D Secure payment process?
The steps involved in a typical 3D Secure payment process are:
The customer enters their card details on the merchant's website and clicks on "pay".
The merchant's website sends the card details and the transaction information to the payment gateway.
The payment gateway forwards the information to the acquirer, which sends a request to the card network to check if the card is enrolled in 3D Secure.
The card network contacts the issuer, which confirms if the card is enrolled in 3D Secure and sends a response back to the card network.
The card network sends a response back to the acquirer, which forwards it to the payment gateway.
The payment gateway sends a response back to the merchant's website, which redirects the customer to the 3D Secure server.
The 3D Secure server displays a secure page where the customer is asked to provide their verification method (password, code, biometric, etc.).
The customer enters their verification method and submits it to the 3D Secure server.
The 3D Secure server validates the verification method with the issuer and sends a response back to the merchant's website.
The merchant's website displays a confirmation page where the customer can review and complete their purchase.
How does 3D Secure verify the identity of the cardholder?
3D Secure verifies the identity of the cardholder by using one or more of these factors:
Something you know: This factor includes something that only you know, such as a password, a PIN, or an answer to a security question.
Something you have: This factor includes something that only you have, such as a code sent to your phone or email, or a physical token or device.
Something you are: This factor includes something that only you are, such as your fingerprint, your face, or your voice.
The combination of these factors provides a strong authentication that confirms that you are who you say you are.
3D Secure challenges and solutions
What are some of the challenges faced by 3D Secure implementation and adoption?
Some of the challenges faced by 3D Secure implementation and adoption are:
Lack of awareness and education: Some customers and merchants may not be aware of what 3D Secure is or how it works. They may also have misconceptions or doubts about its security or usability. This may lead to confusion, frustration, or reluctance to use it.
Inconsistent user experience: Some customers may encounter different authentication methods or interfaces depending on their card issuer, card network, or device. This may cause inconsistency, confusion, or inconvenience for customers who expect a seamless and uniform payment experience.
Poor performance and compatibility: Some customers may experience delays, errors, or failures during the authentication process due to technical issues or compatibility problems. This may affect their satisfaction and trust in online payments.
How does 3D Secure 2.0 address some of the limitations of the original protocol?
To overcome some of these challenges, Visa and Mastercard have developed a new version of 3D Secure called 3 D Secure 2.0 or 3DS2. This version introduces several improvements and features that enhance the security and user experience of online payments. Some of these features are:
Risk-based authentication: 3DS2 uses a risk-based approach that analyzes various data points (such as device, location, behavior, transaction history, etc.) to determine the level of risk associated with each transaction. Based on this risk assessment, the issuer can decide whether to approve the transaction without additional authentication, request a simple authentication (such as a one-time password), or request a strong authentication (such as a biometric verification). This way, 3DS2 can reduce the number of unnecessary or intrusive authentication requests and provide a smoother and faster payment experience for customers.
Mobile-friendly design: 3DS2 is designed to be compatible and responsive with different devices and platforms, especially mobile devices. It supports native mobile applications, biometric authentication methods, and embedded browser solutions. It also adapts to different screen sizes, orientations, and resolutions. This way, 3DS2 can provide a consistent and convenient payment experience for customers who use their mobile devices to shop online.
Regulatory compliance: 3DS2 is aligned with the latest regulatory requirements and standards for online security and data protection, such as the Payment Services Directive 2 (PSD2) in Europe and the General Data Protection Regulation (GDPR) in the European Union. PSD2 requires online transactions to use strong customer authentication (SCA), which is a form of two-factor authentication that uses at least two of the three factors mentioned above (something you know, something you have, something you are). GDPR requires online businesses to protect the personal data and privacy of their customers and to obtain their consent before collecting or processing their data. By using 3DS2, online businesses can comply with these regulations and avoid penalties or fines.
How can online businesses integrate 3D Secure into their checkout flow?
To integrate 3D Secure into their checkout flow, online businesses need to work with their payment service providers (PSPs) or payment gateways to enable the protocol on their websites or applications. Depending on the PSP or gateway, online businesses may have different options or methods to implement 3D Secure, such as:
Hosted payment page: This method involves redirecting the customer to a secure payment page hosted by the PSP or gateway, where they can enter their card details and complete the authentication process. This method is easy to implement and does not require much technical knowledge or resources from the online business.
API integration: This method involves integrating the PSP's or gateway's API into the online business's website or application, where they can collect the card details and initiate the authentication process. This method gives more control and flexibility to the online business over the look and feel of their checkout flow.
SDK integration: This method involves integrating the PSP's or gateway's SDK into the online business's native mobile application, where they can collect the card details and initiate the authentication process. This method provides a seamless and native payment experience for mobile customers.
Regardless of the method chosen, online businesses should ensure that they follow the best practices and guidelines provided by their PSPs or gateways to optimize their checkout flow and customer experience.
Conclusion
In conclusion, 3D Secure is a protocol that provides an extra layer of security for online card payments by requiring an additional verification step from the cardholder. By using 3D Secure, online businesses can reduce fraud and chargebacks, increase customer trust and loyalty, and improve conversion rates. The latest version of 3D Secure, 3DS2, introduces several improvements and features that enhance the security and user experience of online payments, such as risk-based authentication, mobile-friendly design, and regulatory compliance. Online businesses can integrate 3D Secure into their checkout flow by working with their payment service providers or payment gateways and choosing the best option or method for their needs.
If you are an online business owner who wants to provide a secure and smooth payment experience for your customers, you should consider adopting 3D Secure for your online transactions. You will not only protect your business from fraud and chargebacks, but also boost your customer satisfaction and retention.
FAQs
What is the difference between 3D Secure and 3DS2?
3D Secure is the original protocol that was created by Visa and Mastercard to provide an extra layer of security for online card payments. 3DS2 is the new version of 3D Secure that introduces several improvements and features that enhance the security and user experience of online payments, such as risk-based authentication, mobile-friendly design, and regulatory compliance.
How can I tell if a website supports 3D Secure?
One way to tell if a website supports 3D Secure is to look for the logos or symbols of the protocol on the checkout page or the payment form. These logos or symbols may vary depending on the card network or the card issuer, but they usually include the words "Verified by Visa", "Mastercard SecureCode", "American Express SafeKey", or "3D Secure". Another way to tell if a website supports 3D Secure is to check if you are asked to provide an additional verification step after entering your card details and clicking on "pay". This verification step may involve entering a password, a code, or a biometric verification.
What if I forget my 3D Secure password or code?
If you forget your 3D Secure password or code, you can request a new one by following the instructions on the 3D Secure page. Depending on your card issuer, you may be able to reset your password or code online, by phone, or by email. You may also be able to use an alternative verification method, such as a biometric verification, if your device supports it.
Does 3D Secure work with all cards and banks?
3D Secure works with most cards and banks that are part of the Visa, Mastercard, American Express, or Discover networks. However, not all cards and banks are enrolled in 3D Secure by default. Some cards and banks may require you to activate or register your card for 3D Secure before you can use it online. You can check with your card issuer or bank if your card is enrolled in 3D Secure and how to activate or register it if it is not.
Does 3D Secure guarantee that a transaction is not fraudulent?
3D Secure does not guarantee that a transaction is not fraudulent, but it does reduce the likelihood of fraud by adding an extra layer of security for online card payments. 3D Secure verifies that the person making an online purchase is the legitimate owner of the card being used, which makes it harder for fraudsters to use stolen cards or card details online. However, 3D Secure does not prevent other types of fraud, such as phishing, malware, or identity theft. Therefore, you should always be careful and vigilant when shopping online and protect your personal and financial information from unauthorized access or use. 44f88ac181
