U.S. Payments Forum launches EMV 3DS Mini-Series

The U.S. Payments Forum just released the first instalment in its newly launched EMV 3DS Mini-Series, which is aimed at promoting secure ecommerce practices through the adoption and optimization of EMV 3-D Secure (EMV 3DS). The quick-read resource brief offers merchants, acquirers and issuers a foundational understanding of the protocol's architecture, benefits and implementation challenges—marking the beginning of a broader educational effort to strengthen online payment security.

EMV 3DS is a globally recognized authentication protocol that facilitates secure data exchanges between merchants and card issuers. Used effectively, it can reduce eCommerce fraud, raise approval rates, protect merchants from chargebacks, and enhance customer trust in digital transactions. Despite its promise, EMV 3DS adoption in North America remains limited, primarily due to concerns over checkout friction and the complexity of integration.

The new brief explains how EMV 3DS functions across three primary domains: acquirer, issuer, and interoperability. These include systems like the 3DS client and server (on the acquirer side), the directory server (ensuring message routing), and the access control server (on the issuer's end), which authenticates cardholders during online transactions.

Stronger security, lower fraud risk

One of the standout features of EMV 3DS is its ability to support both traditional Primary Account Numbers (PANs) and newer network tokens, offering a flexible approach to secure payment processing. The protocol also helps shift fraud liability from merchants to issuers under certain conditions, which can be a strong incentive for adoption, the forum pointed out.

Use cases covered in the brief include high-risk or high-value transactions, card-on-file account setups and cross-border ecommerce. As EMV 3DS evolves, emerging applications are also on the horizon, including the use of mobile driver's licenses and biometric data for identity verification—promising both increased security and a streamlined user experience.

The brief underscores EMV 3DS's benefits: better fraud detection for issuers, reduced chargebacks for merchants and improved customer trust across digital channels. By reducing fraud rates, merchants can maintain stronger relationships with issuers and minimize disruptions caused by high-risk transaction flags.

Adoption challenges and looking ahead

Notably, the brief addresses the persistent hurdles that have kept EMV 3DS adoption relatively low in the U.S. These include concerns over increased cart abandonment due to added authentication steps, inconsistent merchant data quality that can disrupt fraud detection, and the significant technical lift required to implement asynchronous transaction flows.

To help counter these concerns, EMV 3DS 2.x introduced improvements that minimize friction, challenging cardholders only when necessary. The forum emphasized that while implementation can be complex, the long-term benefits—improved approval rates, fraud protection and customer satisfaction—far outweigh the initial hurdles.

"EMV 3DS is no longer just a fraud-prevention tool; it's a path to building trust and streamlining online commerce," said members of the U.S. Payments Forum's Payments Fraud Working Committee. "Our goal with this mini-series is to break the protocol down into digestible pieces that merchants and providers can act on today."

The forum also highlights that international regulatory environments—such as Europe's PSD2 and India's nationwide ecommerce mandates—have driven broader EMV 3DS adoption. While the United States lacks similar mandates for now, the brief suggests that regulation may follow suit. Merchants with international reach are encouraged to align early and adopt the protocol to smooth cross-border transaction experiences and stay ahead of compliance trends.

Future installments of the EMV 3DS Mini-Series will address more advanced use cases and topics, including 3DS "Data Only" flows and 3RI (three-domain secure requestor initiated) transactions. These entries aim to support both first-time adopters and seasoned payment professionals looking to fine-tune their fraud prevention strategies.

The full brief and related resources are available for free at the U.S. Payments Forum's website. As cyber threats continue to escalate, this series promises to be a timely and practical tool for stakeholders looking to protect their digital storefronts and their customers.
