3D Secure is an authentication protocol that adds an extra layer of security for online credit and debit card transactions. It asks the cardholder to verify their identity with a password or a one-time code, keeping fraud at bay.

Here’s how it works: when a customer shops online, the merchant’s payment gateway pings the card issuer to check the cardholder’s identity. The issuer then prompts the cardholder to enter their 3D Secure password or a code sent to their phone or email. Once they nail that step, the transaction gets the green light, and the payment goes through.

This protocol shines in the payment processing world. Known as an authentication protocol, 3D Secure powers up online payment security. Big players like Visa (with “Verified by Visa”) and Mastercard (with “SecureCode”) use it for cardholder verification and fraud prevention. It ensures the person swiping the card online is legit, protecting merchants and customers alike from shady transactions.
