Banking App Localization for EU Compliance

Quick answer — The European Accessibility Act has applied since 28 June 2025 and names consumer banking, so retail banking apps in the EU are generally in scope. On mobile the work is native accessibility APIs, authentication screens and the store listing, which sit outside a web audit.

Vitra.ai Universe covers the app, document and video surfaces involved.

A web audit does not cover the app

Most banks run their accessibility work against the website, then assume the app inherits it. It doesn't. Mobile accessibility runs through platform APIs — VoiceOver and TalkBack read what the accessibility label says, not what is drawn on screen.

So an icon-only button with no label is invisible, in every language. And a button whose label was translated in the visual layer but not in the accessibility layer is worse: it reads out the old language while showing the new one.

Authentication is the screen that has to work

Strong customer authentication puts a time limit on comprehension. The customer has a short window, an unfamiliar screen and a transaction they may not recognise.

If any screen deserves a native speaker rather than a review pass, it's this one.

The store listing counts

The listing is read before install, by someone searching in their own language, and it is often the only page a prospective customer sees. Screenshots with text baked into the image are the usual weak point — they're image assets, so they skip the translation pipeline entirely.

Video dubbing covers app preview video, and subtitles matter here because store previews autoplay muted more often than not.

Where this article stops

Whether your services fall in scope, and what each member state layers on top of the directive, is a legal question for your counsel. The EAA is a directive, so national implementations differ.

The general localization work sits in banking app localization. The build side is above: label the controls, translate the accessibility layer and not just the visual one and not just the visual one, and treat the authentication screens as the ones that cannot be approximate.

FAQ

Does an accessibility audit of a bank website cover the app? No. Mobile accessibility runs through platform APIs, so VoiceOver and TalkBack read the accessibility label rather than what is drawn on screen. An icon-only control with no label is invisible regardless of language.

What is the worst accessibility failure in a translated banking app? A control translated in the visual layer but not the accessibility layer. The screen reader announces the old language while the screen shows the new one, which is more confusing than leaving it untranslated.

Which banking app screens most need native-speaker translation? The strong customer authentication flow. The customer has a short time window, an unfamiliar screen and a transaction to verify, so an untranslated merchant name or a truncated error defeats the whole purpose.

Do app store screenshots need translating? Yes, and they are the usual gap. Text baked into screenshot images is an image asset, so it bypasses the translation pipeline while being the first thing someone searching in their own language actually sees.
