TLDR: Artificial intelligence is fundamentally transforming global money movement, moving from a peripheral tool to the core of payment systems. Executives from Discover Network and Worldpay highlight AI’s benefits in customer service, back-office automation, and especially in real-time fraud detection. However, they also acknowledge the dual nature of AI, as generative tools empower fraudsters, necessitating continuous innovation and robust data management. The future of payments is envisioned as agent-led commerce, emphasizing the critical need for trust and collaboration across the ecosystem.
Artificial intelligence (AI) is no longer a peripheral tool but has become the foundational backbone of global payments infrastructure, fundamentally reconfiguring how money moves around the world. This transformation is streamlining back-office operations, enhancing customer service, and revolutionizing fraud prevention, according to insights from Judith McGuire, Senior Vice President of Global Products at Discover Network, and Ian Hillis, Senior Vice President of Growth at Worldpay.
McGuire highlighted three key areas where AI is delivering significant benefits. Firstly, in customer service, AI assists with scripting, prompting, and providing agents with more comprehensive information, leading to more impactful customer interactions. Secondly, AI is proving invaluable in automating repetitive back-office tasks, freeing up human employees to focus on more critical work. Most notably, McGuire emphasized AI’s role in unlocking the power of data, enabling faster decision-making, network monitoring, and substantial fraud reduction. She stressed the “absolutely essential” need for human oversight, rigorous testing, and robust AI deployment guardrails.
Ian Hillis noted that software platforms have been early adopters of AI, leveraging it to improve engineering efficacy and platform support, particularly within payments. These platforms, driven by a desire for rapid growth, utilize AI to “abstract away the complexity that can be associated with payments while including the advantages mentioned earlier.”
Both executives underscored that security remains the most pressing challenge, describing payments fraud as a continuous “game of cat and mouse.” The emergence of generative AI tools has armed fraudsters with unprecedented capabilities. Hillis warned, “Unfortunately, the same advantages AI provides of speed, improved actions, lower cost and better fidelity apply to the fraudsters as well. Anyone can hop onto any free-to-use gen AI tool, and pretty quickly, you can have a realistic avatar and supporting credentials. Five years ago, that took significant resources and time. Today, we have to be the ones to stay ahead of that.” McGuire elaborated on Discover Network’s adaptive strategies, stating that AI is “essential to contributing to security of the network,” primarily by monitoring transactions to verify legitimate users. AI models, trained on extensive transaction datasets, can detect anomalies in real-time by evaluating hundreds of variables—such as location, device fingerprint, transaction history, and subtle behavioral cues—all within milliseconds. Hillis added that “fraud defense lives and dies on data,” revealing that Worldpay has been embedding AI across its core payments infrastructure for nearly a decade, with models trained on an astounding “55 billion transactions annually, 135 currencies, [and] 174 countries.”
Effective data management is deemed the linchpin of AI success. McGuire asserted that the AI revolution will fundamentally alter how companies manage data, demanding that it be “accessible, understandable and scalable in a much different way than they have previously… managing data is going to be the core to facilitating this AI revolution.” Hillis used a culinary metaphor to illustrate this point: “AI without data is like a recipe without ingredients. AI with mediocre data is a recipe that’s going to be fed to the dog under the table. While modern AI has reduced the need for perfect data, the better the ingredients, the better the dish.”
Despite the significant progress, both leaders acknowledged that the payments industry’s adoption of AI is still in its nascent stages. McGuire emphasized the need for “thoughtful policy and delivery approaches in place as an ecosystem,” advocating for industry-wide collaboration to build trustworthy policies and mechanisms for end-customers. Hillis pointed out that “AI in payments isn’t perfect yet, and every new breakthrough is going to carry unresolved friction.” He stressed the criticality of “training and tuning” and highlighted that “transparency gaps remain. Black box AI can backfire if merchants can’t explain outcomes.”

The discussion also ventured into the revolutionary potential of “agent-led commerce,” where AI systems possess the capacity for autonomous action. Hillis described it as “the closest thing I’ve seen in payments to sci-fi magic,” with the potential to fundamentally shift trust from the transaction cart to the underlying infrastructure. He foresees “supercharged conversion rates, minimization of cart abandonment,” and optimized pricing and supplier matching for merchants, leading to lower customer acquisition costs. McGuire echoed the sentiment, emphasizing that the conversation around agentic commerce will revolve around “trust.” She questioned how to build a “truly trustworthy environment in this new world” where AI agents might impersonate cardholders, merchants, and acquirers, concluding that “creating that trust is going to be key to getting consumers engaged on a wide scale.”
