Mastercard and DBS Bank Complete Taiwan’s First Agentic AI Payment

Agentic AI is shifting commerce from human-initiated checkout toward software that can search, decide and pay within a user’s mandate. That raises new demands around identity, authorization, fraud controls and disputes, making payment infrastructure a strategic battleground. Mastercard is extending its card network, tokenization and transaction data into the “prompt economy,” seeking to preserve its role as a trusted intermediary as banks, Visa and technology platforms build competing rails for autonomous commerce.

Mastercard launched Agent Pay for Machines on June 10, 2026, enabling continuous machine-to-machine payments across cards, bank accounts and stablecoins, including microtransactions worth fractions of one cent. More than 30 early participants include Adyen, Stripe, Coinbase and Cloudflare. On the company’s July 30 earnings call, Chief Executive Michael Miebach said Mastercard’s global network and data scale should keep it central to agentic commerce despite competition from banks and technology giants, as the company moves the product from pilots toward broader adoption.

The payments industry is shifting from purchases initiated by people to transactions researched, selected and executed by AI agents. That transition could redraw control over authorization, customer relationships, authentication and liability, making trust a competitive requirement rather than a supporting feature. For networks such as Mastercard, preserving security, privacy, transparency and recourse will determine whether agentic commerce can move beyond pilots and operate at global scale.

At ACI Worldwide’s two-day Payments Unleashed EMEA forum in London on June 29-30, 2026, Mastercard Vice President of Product Management Patricia Ferrer joined executives from Amazon and ACI to discuss the agentic buyer. The session focused on enabling agent-initiated payments while limiting fraud and false declines. The trust gap remains stark: an ACI-commissioned YouGov survey of 2,080 UK adults in June found only 17% would trust an agent with their payment data.

As AI agents move from supporting decisions to making purchases autonomously, traditional payment systems—in which people initiate and complete transactions one at a time—are ill-equipped for round-the-clock, high-frequency and low-latency machine-to-machine commerce. Mastercard therefore expanded on its 2025 Agent Pay offering with AP4M, allowing businesses to define agent identities, authorization rules and spending limits as the foundation for controlled autonomous commerce.

Mastercard formally launched Agent Pay for Machines (AP4M) on June 10, 2026, U.S. time. The protocol can process microtransactions of less than 1 cent across global payment networks and provide guaranteed multi-rail settlement through cards, accounts and stablecoins. More than 30 companies joined the initial rollout, including OKX, Coinbase, Stripe, Adyen and Cloudflare.

AI agent payments allow systems not only to recommend products but also to complete transactions autonomously within spending limits and authorizations set by users. The significance of the collaboration between Banco Santander and Mastercard lies in bringing this form of agentic commerce into a regulated banking framework and testing whether existing payment networks can maintain security, privacy and consumer protection.

On March 2, 2026, Banco Santander used Mastercard Agent Pay in a controlled environment, with PayOS providing end-to-end orchestration, to complete Europe’s first live transaction initiated and executed by an AI agent through Santander’s existing payment infrastructure. The companies did not disclose the transaction value and stressed that the project remains a pilot and has not been commercially launched. They plan to expand testing and explore additional use cases.
