3D Secure is an advanced security framework used in online payments to protect both consumers and merchants from fraudulent transactions. The system works by introducing an additional authentication step during the payment process, requiring cardholders to verify their identity before a transaction is completed. This extra layer of security is supported by global card networks under names like Verified by Visa, Mastercard SecureCode, and SafeKey by American Express.
The authentication process starts when a customer enters their card details for an online purchase. If 3D Secure is enabled, the customer may be directed to a verification page where their bank requests identity confirmation. Methods can include entering a password, providing a one-time PIN (OTP), or using biometric authentication. Only after the customer’s identity is verified does the payment proceed.
For businesses, 3D Secure provides a dual advantage: it enhances consumer trust by ensuring secure transactions and reduces liability for fraudulent purchases. The introduction of 3D Secure 2.0 has made the system more user-friendly by integrating risk-based authentication, allowing most transactions to be completed without interrupting the checkout process for trusted customers. This innovation makes online shopping safer and more seamless.
