An AI Agent Just Bought a Coffee Tasting in Denmark. Now the Card Networks Want to Know Who It Was.

Mastercard and Danske Bank completed what they describe as Denmark's first payment in which an AI agent handled both the purchase and the payment for a customer, booking a coffee tasting through Mastercard Agent Pay. At the same time, Visa, Mastercard, and Ant International have begun building a shared "Know Your Agent" framework so payment networks can recognize trusted AI agents across ecosystems.

Denmark's First Fully Agentic Transaction

Mastercard announced on Monday, Sept. 21, that it had helped Danske Bank complete a transaction in which an AI agent made both the purchase and the payment on a customer's behalf, according to PYMNTS. The agent booked a coffee tasting through Priceless.com, Mastercard's experiences platform. The companies said it was the first time in Denmark that an AI agent had made such a purchase and payment.

The transaction ran on Mastercard Agent Pay, the company's program for payments initiated by AI agents. An AI agent here means software that can act for a person, not just give advice: in this case, choosing and paying for a booking. According to the release, the transaction shows how agents can buy things for customers while making sure payment happens with the customer's permission and "under a secure and verifiable framework."

"AI can help make everyday life simpler, but trust and security must come first," said Erik Gutwasser, division president for Mastercard Northern Europe. "Agent Pay is designed to ensure that AI-powered transactions are transparent, securely authenticated and always under the consumer's control. At the same time, the solution gives card issuers better insight into transactions initiated by AI agents."

Danske Bank struck a similar note. "At Danske Bank, we are exploring the possibilities of the new technology with a strong focus on customer value, trust and control," said Mark Wraa-Hansen, the bank's head of personal banking for Denmark.

PYMNTS also notes that Mastercard recently debuted Agent Pay for Machines, a service that lets agents transact with each other. That is the agent-to-agent end of the spectrum, where no human taps a button at the moment of payment.

The Identity Problem: Who Is This Agent?

Every card payment rests on a basic question: is this really the customer, and did they authorize it? Banks answer it with a process called Know Your Customer, or KYC, the identity checks financial firms run before and during a customer relationship. When an AI agent is doing the buying, a second question appears: which agent is this, who is responsible for it, and is it acting within the permissions it was given?

That is the problem Visa, Mastercard, and Ant International are trying to address together. On Sept. 10, the three companies said they had begun collaborating on a Know-Your-Agent interoperability framework, Reuters reported. The framework would let card networks, digital wallets, agent platforms, and online marketplaces recognize trusted AI agents across different payment ecosystems, while each keeps its own approval and risk-management processes.

According to The Next Web, the companies named three areas of work:

• Operator traceability across networks. Linking each agent to a validated operator, cardholder, or business.
• Shared certification. Assessing each agent against security and behavioral requirements.
• Continuous monitoring. Watching each agent using identity and transaction signals.

Building on Three Existing Protocols

The framework does not start from scratch. It builds on protocols each company already has for agent payments: Visa's Trusted Agent Protocol, Mastercard Verifiable Intent, and Ant International's Agentic Mobile Protocol. A protocol, in this sense, is a shared set of technical rules. The companies said they will explore ways to work toward common principles across them.

The work will run through BuildFin.ai, a platform convened by the Monetary Authority of Singapore, the city-state's central bank and financial regulator, that brings together financial institutions, technology providers, and researchers to develop AI solutions for financial services. The Next Web reports it builds on the regulator's Safeguards for Agentic Finance at Runtime (SAFR) framework and covers payment ecosystems in Singapore.

The practical promise is less duplication. "If [an] agent registers with Ant, they don't need to register again with Visa, Mastercard," Jiang-Ming Yang, Ant International's chief innovation officer, told CNBC, as quoted by The Next Web. The companies said the initiative could reduce integration costs and speed up launches of new agentic services.

Mastercard chief digital officer Pablo Fourez said in the announcement that "interoperability across Know-Your-Agent frameworks is essential to making agentic commerce work at scale." Visa's Rubail Birwadker, global head of growth products and strategic partnerships, said: "As AI agents become a bigger part of how people discover and buy, trust must scale with them."

What's Still Missing

It is early. The Know-Your-Agent effort is a collaboration to develop common standards, not a finished specification, and the reports on the announcement do not describe a published technical spec or a launch timeline. The Danske Bank transaction is a single milestone purchase, not a measure of consumer adoption.

Consumer appetite is also an open question. PYMNTS CEO Karen Webster, citing PYMNTS Intelligence research, said consumers' "interest over time in terms of delegating authority has declined, even though usage has increased." In other words, people are using AI more, but they are not necessarily more willing to let it spend their money.

Why It Matters

• Agent payments are moving from demos to real transactions. Denmark's first fully agentic purchase ran on live card infrastructure with a major bank.
• Identity is the bottleneck. Networks need to know which agent is acting and who stands behind it before agent commerce can scale; Know Your Agent is the industry's attempt to answer that.
• Rivals are cooperating. Visa, Mastercard, and Ant International aligning on common principles, under a regulator's umbrella, suggests the industry sees shared trust rules as a prerequisite.
• Consumer trust lags usage. Adoption will depend on people feeling in control, not just on the technology working.
