Danske Bank and Mastercard have completed what they describe as Denmark’s first payment initiated and finished by an artificial intelligence agent, moving agentic commerce from closed experiments into live incumbent bank infrastructure. The pilot, announced on 21 September 2026, involved a customer asking an AI assistant to arrange a coffee tasting through Mastercard’s Priceless.com experiences platform. The agent selected the session, booked it and settled the charge on its own using a Mastercard issued by Danske Bank. Mastercard’s Agent Pay rails handled the payment, while PayOS coordinated the full transaction path from instruction to settlement.
Mastercard says Agent Pay, introduced in April 2025, lets verified AI systems pay on a cardholder’s behalf. Purchases are authenticated with Mastercard Payment Passkeys, and the design is meant to preserve customer control: the person grants permission, the transaction remains visible, and the issuer can see that an agent started the payment. Erik Gutwasser, Mastercard’s Northern Europe division president, said the goal is to make AI-assisted buying simpler without sacrificing transparency or security. Mark Wraa-Hansen, Danske Bank’s head of personal banking in Denmark, framed the test as part of a wider exploration of how customers may interact with financial services.
The Danish transaction follows earlier European Agent Pay pilots, including what Mastercard called Europe’s first live AI-agent payment with Santander in March 2026 and a French first with Worldline and Crédit Agricole. The Danske Bank case is notable because it ran through an incumbent issuer’s card and systems rather than a sandbox wallet. It also raises practical questions on agent authority, consent, liability and dispute handling.
On 22 September 2026, six banks issued joint principles to address those concerns under the title Building Trust in Agentic Commerce. NatWest Group, Bank of America, Capital One, ING Group, Commonwealth Bank of Australia and ASB Bank co-authored the paper. The principles are voluntary and cover transparency, safety, privacy and data, choice, and interoperability. Under transparency, the banks want all parties in an agentic commerce purchase to know when an AI agent is involved and whom it acts for. The paper also warns that agents may promote products or payment methods that give their providers larger commissions even if they are not the best value for consumers.
On safety, the banks call for consumers to control the authority given to agents, secure and auditable entry of payment credentials, involvement of all parties in disputes, and liability placed where risk or error was introduced. NatWest Chief Payments Officer Mark Brant said customers need to trust that they remain in control of payments and that their money is safe. The paper flags unsafe practices, including some providers keying consumer card details into websites and prioritizing payment methods with less protection. It also notes attackers that compromise or impersonate AI agents and merchants. The banks plan to consult policymakers and publish a second paper on implementation.
