Modirum Description

Three-Domain Secure (3DS or 3-D Secure) is a messaging protocol based on XML that allows cardholders to verify their identity with their card issuer during online purchases where the card is not physically present. This system plays a crucial role in minimizing unauthorized card-not-present transactions, thereby safeguarding merchants, issuers, and cardholders from potential fraud. By facilitating the transfer of cardholder information between the key players involved in a CNP transaction—namely the cardholder, merchant, card issuer, and payment processor—3-D Secure enhances security. Originally created by Visa in the early 2000s, the first version of this technology was known as Verified by Visa (VbV). Additionally, other major card brands have embraced services based on the 3-D Secure 1.0 framework, with MasterCard referring to it as MasterCard SecureCode (MCC), JCB International calling it J/Secure, and American Express branding it as American Express SafeKey. A significant advantage of implementing 3-D Secure is the transfer of liability for fraudulent transactions from merchants to card issuers, which effectively lowers the incidence of chargebacks. This system not only boosts consumer confidence in online shopping but also enhances the overall integrity of electronic payment systems.
