How does 3D Secure work?
3D Secure stands for 3 Domain Secure. In short, it’s an additional authentication method for online credit card transactions. It also provides protection against card misuse for the merchant and their acquiring bank, the cardholder and their issuing bank, and the card network associations (Visa, MasterCard).
After the customer clicks the payment button, the 3D Secure window prompts your customer to authenticate and confirm the card payment. This window is usually branded with the MasterCard SecureCode or Verified by Visa logos. Your buyer must enter a personal password (or security code), which will be verified by their card issuer.
