ECB kicks off Digital Euro work with ATMs and payment terminals

The European Central Bank is shifting from policy architecture to practical deployment planning for a potential digital euro. In a published call for industry expertise, the ECB opened two workstreams under its Rulebook Development Group to map how the digital euro would operate across ATMs, payment terminals, and the wider acceptance infrastructure.

The bank outlined that one workstream will develop implementation specifications for ATM and terminal providers, focusing on communication technologies, offline capabilities, and the re-use of existing payment standards. The second workstream will design testing, certification, and approval processes for the payment solutions and infrastructure that would underpin the digital euro ecosystem. This marks a notable move toward translating policy concepts into concrete, interoperable technical requirements across Europe.

At the heart of the initiative is the aim to ensure the digital euro can integrate with current payment systems and hardware while supporting offline transactions and cross-border interoperability within European standards. The ECB’s request for expert input signals a desire to harmonize a future digital currency with the region’s established financial infrastructure, rather than building a separate, standalone system from scratch. The announcement comes as part of ongoing work to define a robust, rules-based framework that could govern how digital euro services are accessed by merchants, payment service providers (PSPs), and end users.

Key takeaways

• The ECB has launched two workstreams under its Rulebook Development Group to define ATM/terminal implementation specifications and to establish testing, certification, and approval procedures for digital euro infrastructure and services.


• Efforts emphasize offline functionality and the reuse of existing European payment standards to support broad interoperability across devices and networks.


• The workstreams will gather input from a cross-section of market participants, including merchants, PSPs, and consumers, with the aim of producing a standardized rulebook for the digital euro ecosystem.


• Europe is coupling policy design with implementation timelines, targeting a 2027-era pilot while clarifying that a final issuance decision depends on the passage of relevant legislation.


• The initiative reflects a broader shift toward practical rollout planning, signaling that the ECB expects to test real-world conditions before any potential issuance.

Aim to bridge policy and practice across Europe’s payments landscape

According to the ECB, one workstream will concentrate on crafting practical implementation specifications for ATM networks and payment terminals. This includes mapping communication technologies, ensuring offline capabilities, and identifying how to reuse and harmonize existing payment standards so that digital euro hardware can function smoothly with current terminals and cashless channels. By prioritizing offline support, the ECB acknowledges the reality that connectivity can be uneven across regions, and resilience will be essential for broad acceptance.

The second workstream will focus on how solutions within the digital euro framework should be tested, certified, and approved before they can be deployed by PSPs and other infrastructure providers. The aim is to create a credible, standardized process that regulators, merchants, and tech partners can rely on as they develop and bring digital euro services to market. Through this structure, the ECB intends to reduce ambiguity around compliance and safety criteria, helping to align a diverse ecosystem of vendors, software platforms, and hardware manufacturers.

Both streams report to the Rulebook Development Group, which includes representatives from merchants, payment service providers, and consumers. The ECB said selected experts are expected to provide technical input to support the development of a standardized rulebook, ensuring that the digital euro’s design choices translate into concrete, testable requirements for market participants.

Timeline and pilot context: moving toward a 2027 milestone

The ECB has previously sketched out a plan to begin selecting EU-licensed PSPs ahead of a 12-month digital euro pilot, anticipated to commence in the second half of 2027. In remarks on Feb. 18, ECB Executive Board member Piero Cipollone indicated that the pilot would involve a limited set of merchants, Eurosystem staff, and PSPs, providing a controlled environment to assess how digital euro transactions unfold in real-world settings.

The pilot is designed to test a narrow slice of the ecosystem—focusing on merchant acceptance, settlement flows, security controls, and user experience—before broader policy decisions are made. The ECB has stressed that its final decision on whether to issue a digital euro will come only after the relevant legislation is enacted, underscoring the program’s regulatory and legislative dependencies as the project moves forward.

The timing aligns with a broader European push to explore programmable money, interoperability, and cross-border payments within a monetary policy framework that remains under public debate. The workstreams’ emphasis on standards, certification, and implementation readiness complements earlier outlining of the Appia roadmap and other tokenized-money initiatives, illustrating a coordinated path from concept to potential deployment.

In practice, the forthcoming rulebook and testing framework would help determine how a digital euro would interact with existing point-of-sale systems, online checkout flows, and offline payment experiences acrossEU member states. The approach seeks to minimize disruption to merchants while maximizing the currency’s reliability, security, and user accessibility across a diverse payments landscape.

What comes next and what to watch

As the ECB progresses through the RDG-led workstreams, market participants will be watching how quickly a standardized rulebook materializes, which PSPs are invited to participate in the pilot, and how the 2027 timeline aligns with legislative developments in the EU. The coordination between policy objectives and implementation specifications will be crucial for assessing the digital euro’s feasibility and potential impact on existing payment rails, cross-border settlement, and consumer protection regimes.

Observers should also monitor how offline capabilities are reconciled with security and risk controls, how interoperability with legacy payment standards is achieved, and how the certification framework will certify both software and hardware components used in digital euro ecosystems. The path from policy to practical deployment remains complex, but the ECB’s latest move signals a deliberate step toward testing and standardization that could shape Europe’s digital monetary future.
