Understanding 3D Secure

3D Secure is a security protocol developed by major credit card companies to enhance the security of online transactions. It is a system that adds an extra layer of authentication to protect against fraudulent activities. 

The system is designed to verify that the person making the purchase is the legitimate owner of the credit or debit card used for the transaction. This section of the article will help you understand what 3D Secure is and its evolution into 3D Secure 2.0.

Definition of 3D Secure

3D Secure is an online security protocol that helps to reduce the risk of fraudulent transactions. It was first introduced in 2001 by Visa, and since then, it has been adopted by other credit card companies like Mastercard, American Express, and Discover. 3D Secure is also known as Verified by Visa, Mastercard SecureCode, and SafeKey by American Express.

Differences between 3D Secure 1.0 and 2.0

3D Secure 1.0 was introduced in 2001, and it had limitations that affected its effectiveness. The system used a static password that was easy to guess and not very secure. 3D Secure 2.0, on the other hand, is an improvement over the first version. 

It uses advanced technologies to authenticate transactions, such as biometric authentication, SMS OTP, and facial recognition. Unlike the static password used in 3D Secure 1.0, 3D Secure 2.0 provides a more secure and convenient way of authenticating transactions.

How 3D Secure 2.0 Works?

When you make a payment with your credit card on a 3D Secure-enabled website, the authentication process begins. Here's a step-by-step guide to the process:

1. Cardholder initiates a payment: The payment process begins when the cardholder enters their payment details on the merchant's website.
2. The merchant initiates the authentication request: The merchant's payment gateway sends an authentication request to the card issuer's Access Control Server (ACS).
3. ACS sends a challenge request: The ACS sends a challenge request to the cardholder's device. The challenge request could be in the form of a push notification, an SMS, or a one-time password (OTP).
4. Cardholder completes the challenge: The cardholder completes the challenge by entering the requested information on their device.
5. ACS authenticates the cardholder: The ACS verifies the cardholder's identity and sends an authentication response to the merchant's payment gateway.
6. Payment is approved or declined: Based on the authentication response, the payment is either approved or declined.

Role of the Card Issuer, Merchant, and Cardholder

Now that we've covered the authentication process, let's take a closer look at the roles of the key players involved.

Card Issuer

The card issuer is responsible for providing the ACS and managing the authentication process. They also authenticate the cardholder's identity and determine whether to approve or decline the payment.

Merchant

The merchant is responsible for initiating the authentication request and integrating 3D Secure 2.0 into their payment gateway. They are also responsible for managing the payment process and providing a seamless user experience for the cardholder.

Cardholder

The cardholder plays a crucial role in the authentication process by completing the challenge request sent by the ACS. They must enter the requested information accurately and promptly to ensure a smooth authentication process.

Key Features of 3D Secure 2.0
