UX Challenges and Solutions in Bank ATM Accessibility

Although more and more banking services are migrating to the online space, the use of ATMs remains an integral part of everyday financial life. For a responsible financial institution today, making its services equally accessible to all users is no longer merely an option; it is a fundamental expectation, and, in many cases, a strict legal obligation. Our objective was to examine the accessibility landscape of domestic bank ATMs within the framework of a comprehensive UX research and design process, driven by the requirements of the European Accessibility Act (EAA), and to formulate design solutions that provide genuine assistance to users with visual, motor, and cognitive impairments.

We based our work on the requirements of the EN 301 549 (chapters 8 and 11) and WCAG 2.1 AA standards. Since ATMs are closed-functionality systems, we paid special attention to the relevant technical requirements for kiosks. Our challenge involved not only complying with rigorous international and domestic directives but also ensuring that the resulting UX performed reliably in real-world, everyday situations. Solutions that seem perfect on the drawing board or in a laboratory environment often fail in practice, amid the noise of a busy street or adverse weather conditions.

The Standard Framework and Global Benchmarks

Before embarking on field research and testing, it was essential to map existing global and domestic best practices. We identified numerous inspiring examples in the international market. In the United States, institutions like Wells Fargo, Bank of America, and JPMorgan Chase already use talking ATMs and Braille surfaces extensively. In the British market, Barclays, Lloyds Bank, and Halifax are at the forefront of providing audio assistance. UOB in Singapore and Malaysia, and Standard Chartered Bank in Pakistan, provide height-adjustable screens specifically to accommodate wheelchair users. RBC in Canada facilitates access with automated doors, ramps, and barrier-free ATMs with lowered mounting heights.

Significant progress can also be seen in the domestic Hungarian market. A highly innovative solution from Erste is the reduced screen size mode, which allows the entire interface to be comfortably operated from a wheelchair, as the displayed information is condensed and only visible in the lower half of the screen. K&H Bank heavily emphasizes physical accessibility; many of its branches feature ramps, photocell doors, or level entrances without elevation differences. As of Q2 2026, OTP Bank says 75% of its ATMs are physically accessible and 57% feature voice-over capabilities that automatically switch to a talking mode when the user connects earphones.

Research Methodology and the Power of Native Testing

The most valuable phase of our project was native testing, during which we went out into the streets and examined user interactions at real, functioning ATMs. To maximize professional credibility and empathy, we worked closely with advocacy organizations, such as the Hungarian Federation of the Blind and Partially Sighted (Magyar Vakok és Gyengénlátók Országos Szövetsége, MVGYOSZ), the National Advocacy Association of Persons with Intellectual Disabilities and their Helpers (Értelmi Fogyatékossággal Élők és Segítőik Országos Érdekvédelmi Szövetsége, ÉFOÉSZ), and the Salva Vita Foundation. With the help of their experts and participants with lived experience, we gained insights we could never have uncovered in a traditional laboratory setting.

We divided our testing into three main target groups: users with motor impairments, visually impaired users, and individuals with cognitive difficulties. The tasks covered everyday banking routines, primarily cash withdrawals and balance inquiries. Our participants included a 23-year-old with Down syndrome who had never used a bank card before, as well as an electric wheelchair user who was explicitly afraid that the machine would swallow their card if they were not fast enough. Native testing proved that the physical environment – the glare of the sun, the noise of traffic, the spatial constraints of a vestibule – drastically alters how users interact with the interface compared to a highly controlled testing environment.

Furthermore, it brought a crucial emotional factor to the surface: regardless of their specific impairments, all participants shared a deep-seated fear of failure. The dread of a swallowed card, an incorrect PIN, or frustrating the people waiting behind them created significant stress. Therefore, our ultimate design goal became clear: to eliminate this anxiety. We aimed to create an interface that decreases fear and replaces it with a strong sense of safety, ensuring customers feel entirely supported by their bank.

Combating Cognitive Overload and UI Simplification

One of the most striking UX problems we encountered was the phenomenon of cognitive overload. Traditional ATM interfaces tend to overwhelm the user with too much information, advertisements, and complex choices all at once. One of our test participants, who struggled with short-term memory and reading difficulties, found the cluttered screens particularly frustrating. When a user approaches an ATM, their mental model is focused on a single, clear goal: they want to withdraw cash. This process is interrupted by injected questions, such as setting a favorite amount or the complex selection of various banknote combinations.

From a design perspective, the solution was drastic simplification. We reduced visual noise and established a clear visual hierarchy. Clarifying the state of UI elements was a crucial realization. On many ATMs, the user cannot determine whether a specific block of text is clickable on the touch screen. We introduced a clear, universal set of rules: blocks with a white background and high contrast are clickable buttons, while text with other backgrounds is informational only. This distinction instantly reduced the cognitive effort required to scan the screen.

Regarding cognitive accessibility, streamlining the receipt printing process is very important. ATMs confuse the user with duplicated radio buttons or illogically phrased menu items (e.g. "Cash withdrawal with receipt," "Cash withdrawal without receipt," and then ask the user again later in the flow if they want a receipt). During the design process, we minimized the number of decision points and used clear, easily interpretable microcopy. By removing redundant steps, we not only sped up the transaction time but also reduced the anxiety associated with making the "wrong" choice.

Physical and Motor Challenges in Practice

Sections 9.1.1 and 9.1.2 of the EN 301 549 standard define the reachability of controls, prescribing a maximum height of 1.2 meters. In reality, however, the greatest problem for wheelchair users is often not the height itself, but the general approachability. Narrow vestibules, heavy doors that are difficult to open, and the lack of an adequate turning radius frequently make even reaching the ATM physically impossible.

The testing phase revealed a critical, often overlooked distinction among users with motor impairments. The ergonomic needs of a wheelchair user are fundamentally different from those of a person walking with two crutches. A person leaning on crutches does not have free hands. They cannot easily take out their wallet, maintain their balance, and simultaneously navigate a high-mounted touch screen. For them, the presence of physical supports and the logical arrangement of physical input methods (such as the PIN pad) are the most critical factors. Hybrid solutions – where the user must select a function on the touch screen but enter data on the PIN pad – can be particularly disorienting if the interface does not provide clear visual and auditory feedback regarding the change in focus.

Designing for the Visually Impaired: The Audio Guide and Privacy

For visually impaired, blind, and partially sighted users, the standard mandates a 3.5 mm jack connector, screen reader support, and tactile identifiers.

Keyboard navigation via the encrypting PIN pad (EPP) is essential to replace the touch screen. Tests confirmed that deactivating the touch screen functions when earphones are connected is the safest approach. The spatial orientation of visually impaired users is greatly assisted by the standard numeric keypad, where the embossed mark on the '5' key serves as the origin point. We optimized navigation for this physical keyboard by assigning specific functions to dedicated buttons (e.g. "press 1 for cash withdrawal"). This imposes a much lower cognitive load than navigating sequentially through an invisible list using up and down arrows.

Regarding the auditory experience, the technology, often referred to in the industry as text-to-speech (TTS), is typically called an audio guide in banking terminology. During the initial phases, stakeholders sometimes tend to overthink the solutions, for instance, by transmitting instructions and content separately through different channels (right and left ear). Feedback from expert meetings indicated that this spatial arrangement is highly distracting. For them, the accustomed, well-known domestic screen reader voice (commonly known colloquially as the "Szabolcs" voice in Hungary) is the most suitable, without the need for unnecessary spatial audio tricks.

One of the most vital elements of processes designed for visually impaired users is privacy. On a busy street, a blind user cannot see who is standing behind them or who is watching the screen. To eliminate this risk, we designed a dark screen mode. When the user connects their earphones, the system offers to completely dim the screen, ensuring that those standing behind them cannot see any financial data. At the same time, we had to consider life situations where a visually impaired user or someone with cognitive difficulties is accompanied by a helper. For them, we created a "co-working" mode, where the visual elements of the screen remain active alongside the audio guide, supporting joint transaction management.

The Intersection of Security and Accessibility

As established during the native testing phase, a flawless UX must prioritize the user's emotional safety. However, this overarching sense of security frequently intersects with strict banking security protocols. For users with motor or cognitive difficulties, one of the biggest stress factors is the management of timeouts. The fear that the ATM will cancel the transaction and swallow the bank card due to a slower reaction time causes severe anxiety. Based on these findings, we defined the need for clear, highly visible, audible warnings indicating the approaching timeout, along with an unambiguous option to extend the session.

During the project, the issue of error messages generated significant professional debate. The WCAG 2.1 standard explicitly requires the system to accurately indicate the cause of an error to the user (e.g. an incorrect PIN). However, certain strict banking security protocols overrule these principles to ensure physical safety. For instance, to protect users against forced withdrawals, some systems are designed not to immediately flag an incorrect PIN. Because the ATM cannot distinguish between a genuine typo and a user intentionally entering a wrong PIN under duress (e.g. during an armed robbery), the system may allow the user to proceed through the entire withdrawal flow. Only at the very end does it provide a generic error message citing a technical problem. This provides the victim with plausible deniability, making the attacker believe the machine is at fault. While from a pure UX perspective, this creates a frustrating experience for an everyday user who simply made a mistake – and clashes with accessibility standards – the design team must acknowledge and integrate these compromises to prioritize physical security.

Core Accessibility Design Recommendations

Summarizing the most important milestones of our research, we structured our solutions along the following core principles:

• Physical and hardware accessibility: Implementing ramps and automated doors, positioning controls at heights strictly below 1.2 meters, and providing surfaces with Braille and tactile indicators (with special attention to the rapid discoverability of the audio jack connector and the tactile '5' key on the PIN pad).
• Digital and software accessibility: Creating clean interfaces that minimize cognitive overload, using clear contrast ratios, offering an optional dark screen mode for secure audio navigation, and integrating familiar TTS technology with dedicated EPP controls to completely bypass the need for touch interactions.
• Content and linguistic accessibility: Simplifying the UI copy by dropping passive voice, eliminating complex financial jargon, and translating formal banking language into clear, human-centric instructions to provide immediate reassurance to the user.

Conclusion

The accessibility transformation of ATMs has highlighted a fundamental UX truth: inclusive design does not merely serve the interests of a narrow minority. When we simplify a process for those struggling with cognitive difficulties, when we increase the contrast for the partially sighted, or when we make navigation more logical, we are simultaneously creating a faster, safer, and more enjoyable banking experience for all. For the banking sector, accessibility is not just a legal obligation; it is a huge opportunity to increase brand loyalty and user satisfaction.

The project demonstrated that despite technological limitations and strict security protocols, genuine, human-centered solutions can be created in the financial sector through continuous, iterative testing that actively involves the affected demographics. It is highly recommended to involve users with special needs from the very first step in all digital and physical product development, as their feedback represents the most reliable compass toward a truly flawless UX.
