Can't read, won't buy

There’s a quiet conversion killer sitting inside many digital products today.
‍

Millions of users land on a platform, look around for a few seconds, and leave–not because they don’t want what’s being offered, but because they can’t understand it.
‍

The marketing world has a name for this: “Can’t read, won’t buy.” In a physical store, customers can pick up a product, ask questions, or read body language. None of that exists in digital environments. Research published in International Marketing Review shows online shoppers rely almost entirely on words, images, and descriptions when deciding whether to trust a product. When those signals are poorly translated or unfamiliar, ambiguity increases cognitive effort, which in turn leads to drop-offs.
‍

In this article, I explore how localization and UX design shape trust, conversion, and usability in global digital products.

The gap between global payments and local experience

Money is already global. Cross-border payments reached roughly $194.6T in 2024 and are projected to reach $320T by 2032.

That growth shows up in everyday moments: a startup in Singapore paying a contractor in South Africa, a student in Germany sending money to family in Brazil, or a shopper in Canada purchasing goods from a merchant in Japan and paying in yen. Crypto platforms increasingly sit at the centre of these movements–no longer as experimental technologies, but as practical infrastructure for global value transfer.
‍

Yet the UX on many of these platforms still reflects an earlier internet: English-first, region-assumed, and built around a narrow set of payment behaviors. So while today’s technology enables global movement, the actual user experience often doesn’t. And while early crypto users tolerated clunky interfaces because they believed in the technology - they read docs, asked questions in forums, and even debugged their own experience - today’s users are different. They’re no longer experimenting–they’re actually moving money. They’ve set a higher bar for clear and easily understood payment experiences.

One product, many worlds

As designer Scott Berkun once said: “If you don't know who you're designing for, you're designing for yourself.”
‍

In fintech and payments, this isn’t a philosophical observation–it is a business constraint. According to Chainalysis, the fastest-growing crypto regions are APAC (69% growth), Latin America (63%), and Sub-Saharan Africa (52%): all predominantly non-English-first markets. Ignoring this global distribution of users creates what can be called a linguistic butterfly effect, where small translation or presentation errors lead to large trust losses.
‍

In practice, these trust and usability gaps tend to emerge in three broad areas: language, patterns, and symbols.

Language and trust

Over-reliance on English creates friction when users are making financial decisions.
‍

In financial products, trust is the product. When users evaluate a payment flow, they are assessing security, legitimacy, and risk in real time. If the language is unfamiliar, that evaluation becomes harder. Studies show that 75% of consumers prefer purchasing in their native language, and 40% will not buy if content is not localized (CSA Research).
‍

Financial terminology also matters. Words like “wallet,” “KYC,” or “DeFi” may carry different meanings or lack direct equivalents across markets. Strong platforms design for this variation.

UX patterns that don’t travel

Design patterns that work in one region can fail quietly in another.
‍

Payment rails illustrate this clearly. ACH bank transfers are familiar in the United States but may be confusing or unusable in other markets.
‍

Formatting differences also create friction:

• Number formats: $1,000.50 may appear as $1.000,50 in parts of Europe.
• Date formats: 04/05/25 can mean April 5 or May 4 depending on region.

Non-Latin scripts require proper font and rendering support, and reading direction and interface hierarchy expectations differ across cultures.

Symbols, defaults, and cultural context

Small visual signals can influence trust. In Western markets, red often signals urgency or risk, whereas in parts of Asia it represents luck. Numbers also carry cultural meaning: the number four is often avoided in Chinese, Japanese, and Korean contexts because of its association with misfortune.
‍

Or consider tone: some markets prefer stability-focused language while others respond better to growth framing. For example, “Your funds are securely protected while your transaction is being processed” would work well in Japan and parts of Western Europe.

Designing for a borderless economy

True localization goes well beyond translated copy. It means local currency display, familiar payment rails, correct date and number formats, and reading direction. It means trust signals that resonate locally, and marketing and advertising that reflects how people in a specific market actually communicate.
‍

The return on getting this right is real. Data from DeepL shows 96% of B2B leaders report positive ROI from localization, with 65% seeing at least 3x returns. The numbers vary by market and product, but the direction is consistent: localization significantly improves performance.
‍

The crypto and payments landscape is already fragmented across exchanges, wallets, and rails, so reducing friction wherever possible matters. Multi-language and multi-currency support are table stakes. Regional formatting standards should be mandatory. Ultimately the goal should be to serve users in a way that feels clear, consistent, and native–wherever they are.

Closing thoughts

The businesses winning in global payments aren’t necessarily building better products–they’re building products that more people can actually use. And that comes down to one thing: localization.
‍

So don’t treat localization as an afterthought or you’ll risk significantly narrowing your addressable market. If it doesn’t feel native, it doesn’t convert. Or in the words of your users: “Can’t read, won’t buy.”
