3DS Challenge Card Testing Detection

Understanding 3DS

• 3DS (Three-Domain Secure) is a security protocol developed by Visa, Mastercard, and Discover.
• It adds a challenge phase where the card issuer verifies the cardholder's identity during the transaction process.
• 3DS aims to reduce fraud and enhance security in online transactions.

3DS and Card Testing

• 3DS is not intended to interfere with card testing processes.
• Card testing involves validating the card details against a testing environment.
• 3DS simply adds an additional layer of verification without halting the card testing process.

How 3DS Works

• When a transaction is initiated, the merchant sends the card details to the card issuer's server.
• The issuer challenges the cardholder for additional authentication, like a PIN or SMS code.
• The transaction is authorized or declined based on the cardholder's authentication.
