Key Takeaways:

• Nearly a quarter of global payment corridors have average sending costs exceeding 3% of transaction value, with retail remittances averaging 6% globally.
• Only 46% of person-to-person cross-border payments reached recipients within one hour as of 2024, falling short of the G20’s 75% target.
• Trust, low-bandwidth optimization, and tiered KYC are the three pillars of effective cross-border payment UX in underserved regions.
• Regional innovations like USSD in Sub-Saharan Africa, QR interoperability in Southeast Asia, and Brazil’s Pix system show that locally-driven UX design drives adoption.

For instance, moving $200 to a family member in Sub-Saharan Africa incurs, on average, $12 in fees. Furthermore, such a process may take days. For millions of people whose lives depend on cross-border payments to meet their expenses, such a process is not a mere nuisance, but a hindrance to their economic existence.

Cross-border payment UX in underserved regions is where technology, regulation, and financial inclusion converge. Get it right, and you unleash a new world of economic possibility to millions of people priced out of the formal economy. Get it wrong, and you leave them stuck with informal channels that offer much higher risk.

This post is a deep dive into the underlying issues that cause poor UX in cross-border payments, how underserved regions have responded, and what design best practices successful fintech companies use to deliver UX that actually works.

Why Cross Border Payment UX Feels Broken

Furthermore, international payments are not subject to a unified global clearing house. In this case, international payments are made through a chain of correspondent banks instead of a centralized real-time gross settlement system used in domestic payments. Each bank in this chain charges fees and adds foreign exchange markups, thereby delaying international payments. This process involved in international payments has brought about various challenges that need to be addressed in order to provide a seamless user experience.

The impact that this has on users is significant in that around 46% of person-to-person international payments were received within one hour by users as of 2024, which is still lower than the G20 target of 75%. In addition, a quarter of international payment corridors have average sending costs above 3%, and retail remittances average 6% globally.

The table below summarizes the main friction points and their real-world consequences:

“The increased functionality and performance of mobile payment systems, combined with the growing complexity of digital interfaces, present significant challenges for users, particularly in terms of usability, security perception, and task completion efficiency, which directly affect the overall user experience.” (Hsu & Chen, 2022)

Exchange rates remain a key challenge in cross border transactions, as fluctuating and non-transparent rates can significantly impact the final amount received.

Over the past decade, global correspondent banking relationships have declined by roughly one-fifth. As banks exit perceived high-risk corridors, the progress made on reducing remittance fees faces reversal. If current trends continue, it is projected that access to affordable and secure cross-border payment services could become even more limited in the future.

Use Case: KlickEx – Cross-Border Payments Redesign

Problem:
KlickEx sought to revolutionize cross-border payments in the Pacific region by creating an accessible, user-friendly platform.

The primary goal was to develop a solution that would make money transfers and mobile top-ups seamless for Pacific Island communities, while ensuring compliance with financial regulations and maintaining high security standards.  Users—particularly migrant workers—struggled with slow transactions, unclear fees, and low trust in digital platforms, leading to high drop-off rates in key flows like “Add Money” and “Transfer.”

Feature:
We redesigned the KlickEx platform with a mobile-first, user-centric approach tailored to low-bandwidth environments and diverse financial literacy levels. 

Key improvements included:

• Simplified, step-by-step transfer flows reducing cognitive load
• Transparent pricing calculator showing real-time FX rates and total received amounts
• Smart KYC system with automated compliance checks across jurisdictions
• Multi-currency support and integrations with regional payment systems and mobile wallets
• Optimized UX architecture and clear navigation for faster task completion

Result:

• 30%+ increase in conversion rates across key flows

“Add Money” flow: +35.3%

“Money Transfer” flow: +30.7%

• 54.8% completion rate driven by mobile-first design
• 53,000 active users with steady growth of 3,000 new users monthly
• Reduced friction and improved trust through transparency and simplified compliance

How Regional Ecosystems Have Adapted

Underserved regions have not waited for the global banking system to catch up. They have built their own payment infrastructure, one that is appropriate for their constraints, connectivity realities, and cultural behaviors. Underserved regions have created innovative solutions that are tailored to their needs. They have harnessed the power of technological innovation to solve their challenges, including financial and digital exclusion. These initiatives are quickly increasing the reach of cross-border payments in emerging markets.

Sub-Saharan Africa: USSD and Mobile Money

Sub-Saharan Africa leads global mobile money adoption, with digital channels used by over 70% of adults for peer-to-peer payments. The backbone of this system is USSD, a protocol that works over basic GSM networks without smartphones or data plans. This makes it uniquely accessible.

Mobile money systems provide crucial support for users who lack access to traditional banking, promoting financial inclusion across the region.

However, USSD comes with real UX constraints: a 160-character limit per screen, three-minute session timeouts, and no visual confirmation screens. For first-time users, a single unclear step can create what UX researchers call “cognitive scarring,” a fear of making irreversible mistakes that leads to abandonment.

Southeast Asia: QR Code Interoperability

Southeast Asia skipped credit card infrastructure almost entirely in favor of interoperable QR networks. National standards, including Indonesia’s QRIS, Thailand’s PromptPay, Singapore’s PayNow, and Malaysia’s DuitNow, have expanded beyond domestic use to create a regional payment zone.

The user experience is also improved through the QR code payment system by providing options for local preferences in payment methods and interfaces. This is making the user experience for cross-border payments much smoother.

The digital payment market share in this region is also captured by this QR system by mid-2025. A Thai user can instantly pay using their home country app after scanning the QR code in Malaysia with transparent exchange rates applied in real time.

Latin America: Pix and the Cash Bridge

Brazil’s Pix system, launched in 2020, is used by 76% of adults and processes 45% of all national payments. Its UX is built around simplicity: users send funds 24/7 using a “key” such as a phone number or email.

However, in a country like Mexico, which still has a high level of dependence on cash, a different approach is followed in OXXO Pay. A user makes a purchase online and receives a barcode after which he completes a cash transaction at an OXXO outlet. A merchant plays a significant role in this system by facilitating payments and allowing users to use digital tools that enable seamless cash-to-digital transactions.

The idea behind Pix and OXXO Pay is to overcome issues in payments by offering users a simple and user-friendly tool that acts as a bridge between digital and cash economies.

Core UX Design Principles for Underserved Markets

Building payment products for populations with limited formal education, inconsistent connectivity, and low-end devices requires adapting standard UX principles to prioritize three things above all else: trust, reliability, and accessibility. Trustworthy and robust security features are non-negotiable and essential for cross-border payment UX in these markets.

“Human-centered design, as the core mindset of design thinking, ensures that the solutions created are relevant, practical, and beneficial for users by deeply understanding their experiences, needs, emotions, and real-life contexts throughout the entire design process.” (Maryono & Ghina, 2025) 

1. Make Trust Visible

In underserved regions, trust is not a nice-to-have; it is a functional requirement. Users often fear that a single input error will result in the permanent loss of their money.

“Authenticity may initiate user engagement, but long-term relationships in digital environments are sustained through trust, which is built on consistent emotional communication, transparency, and alignment with user values rather than purely functional or technical performance.” (Wang, 2024)

Effective trust-building design includes:

Transparent fee disclosure before transaction confirmation, showing exactly what the sender pays and what the recipient receives

Real-time status indicators similar to a delivery tracker, showing where funds are in the payment chain

Visible security cues such as lock icons, green success states, and instant notifications for each transaction attempt, clearly signaling a secure transaction process. Incorporating advanced fraud detection measures, such as AI-driven monitoring, further reassures users that their cross border payments are protected from suspicious activity.

A strong focus on these elements is essential to ensure user confidence in cross border payment UX.

2. Optimize for Low-End Hardware and Bandwidth

A large share of fintech users in mobile-first markets rely on 2G or 3G connections and older devices. Poorly optimized interfaces lead to failed checkouts and payment abandonment. Optimizing the payment site and related websites for low-end devices and slow connections is crucial to ensure accessibility and a seamless cross border payment UX for all users.

3. Design for Cognitive and Language Inclusion

63% of users drop out of the onboarding process when the flow is perceived as too complicated. One major factor for this is the use of financial jargon. Creating an onboarding flow that meets the preferences of the user, such as languages and aesthetics, creates a more personalized and trustworthy user experience.

Changing “Initiate Disbursement” to “Send Money,” or “Nostro Account Settlement” to “Transfer to Partner Bank,” for instance, significantly decreases the cognitive load. Providing tooltips and walkthroughs also educates the user without overwhelming them. Another aspect is the incorporation of the needs and expectations of different user groups in the design of the user interface.

Solving the KYC Gap

There are about 850 million people worldwide who don’t have the formal ID documents necessary for conducting traditional KYC.

Tiered KYC systems help solve this problem in that they offer users the opportunity to open basic accounts with minimal documentation, with the amount of transactions they can make increasing as the verification process is taken further.

Different models, like payment, credit, and trust creation models, are used in order to accommodate the varying needs of verification while incorporating fintech companies in diverse markets:

Where formal IDs are unavailable, alternative verification methods are gaining traction: community leader attestations, group-based microfinance validation, and digital footprint analysis using consistent device and telecommunications usage patterns. It is important to evaluate the effectiveness and inclusivity of these approaches to ensure they meet regulatory requirements and support broader financial access.

What the Best Platforms Get Right: Three Case Studies

Chipper Cash serves millions of customers across nine African countries with a no-fee P2P model, achieving significant depth in market penetration through high active user rates and transaction volumes relative to local GDP. Their success comes from diaspora-focused language in product design, integrated financial literacy content within the app, and localized onboarding flows for each country. A stablecoin partnership via StableChain now enables faster, lower-cost settlement across their network.

Remitly reaches 170+ countries and 5,100+ corridors by leading with transparency. Platform success is measured using metrics such as payment volume, penetration rates, and revenue per user normalized by GDP per capita. Their redesigned send experience shows users a side-by-side comparison of transfer options, exact fees, and real-time status. Specialized experiences, like “Remitly for Seafarers,” address the specific documentation and connectivity needs of niche user groups.

DANA in Indonesia solved a critical discoverability problem. UX research provided insight into user behavior, revealing that 78.6% of users withdraw cash through Alfamart outlets, but users struggled to find the withdrawal feature during emergencies. The idea for a search-bar-first approach emerged from this research, leading to improved microcopy for withdrawal procedures and the addition of biometric confirmation for cash withdrawal token codes.

The Road Ahead: CBDCs, Stablecoins, and Project Nexus

The next step in the evolution of cross-border payments is tokenized value. Stablecoins and CBDCs have the potential to eliminate the need for the traditional chain of correspondent banking entirely. This is because they have the capability for instant settlement at a fraction of the current cost. The current trends and innovations in the field, such as real-time payments, blockchain technology, and digital currencies, are what will shape the future of cross-border payment UX. This is because they are making payments faster, more transparent, and efficient.

Project Nexus is integrating national fast payment systems in ASEAN countries. This is with plans for future integration in China, India, and the EU by 2029-2030. This is what will shape the future of international payments because it is making them seamless. An example of this is the use of blockchain technology in cross-border payments.

With the ISO 20022 messaging standard, which also carries richer data in XML format along with the payments message, this infrastructure promises fewer false positives in anti-money laundering checks, improved reconciliation, and an enhanced automated customer experience for gig economy payments and B2B transactions. Machine learning and AI, along with open banking, are helping create a more intelligent automated world with improved fraud detection and reconciliation by analyzing transactional data in real-time. Moreover, these technologies are helping make the financial system more inclusive and integrate data for the development of more innovative cross-border payment solutions. For this to happen, however, continued collaboration and regulatory efforts are required. There is hope for a more inclusive and efficient cross-border payment system in the future.

Build Payment Experiences That Actually Work

Cross-border payment UX in underserved regions is a design challenge with human stakes. Good cross-border payment UX is critical to the success of businesses and people alike, as it empowers them to survive and thrive in an ever-evolving digital financial world. The platforms that win are those that treat transparency as a minimum requirement, obsess over infrastructure optimization, and build onboarding experiences that meet users where they are, not where traditional banking expects them to be. Designing for underserved regions is important because it has a real-world impact and makes a real difference in the world.
