Shaping a consumer prepaid debit card into a clear, user-centered mobile experience that supports seamless onboarding, confident spending, and intuitive money management.

Project

Company: uLink
Industry: Consumer Fintech
Scope: Website + Debit Card App Flows
Market: United States
Role: Product Designer
Focus: Activation, onboarding, transactional clarity
Impact: Improved activation clarity and cross-channel consistency


Overview

Designing a consumer debit experience within a cross-border fintech ecosystem. uLink Card is a U.S.-based prepaid Mastercard built for everyday spending, integrated with the uLink ecosystem to enable international money transfers directly from available balance.

As part of the product design team, I contributed to both the public website experience and core in-app UX flows. My work connected acquisition, onboarding, activation, and transactional clarity into a cohesive consumer financial experience.

This project required aligning marketing, compliance, and product execution within a regulated environment.


The Challenge

The product needed to clearly communicate:

• Everyday debit card usability in the U.S.
• No credit check onboarding
• Transparent fee structures
• Integration with international transfer functionality
• Clear activation and account management steps

Financial products operate on trust. Ambiguity around fees, activation, or functionality can directly impact adoption and retention.

The experience needed to be simple without being oversimplified, compliant without feeling heavy, and connected across web and app touchpoints.

Solution - App

My Contribution

Within the mobile experience, I designed and shipped UX across:

• Card activation flows
• Account setup steps
• Transaction confirmation and status patterns
• Error state messaging and resolution flows
• Balance visibility and usage patterns

Engineers built directly from my design specifications, and flows were refined through cross-functional collaboration with product and engineering.

The goal was to ensure clarity, consistency, and trust from activation through daily usage.


Measurable & Operational Impact

Measurable operational improvements included:

• Reduced ambiguity in activation and onboarding steps
• Improved alignment between web messaging and product behavior
• Fewer clarification loops during implementation cycles
• Reusable UX components that supported faster feature rollouts
• Increased structural consistency across debit and remittance experiences

The result was a more cohesive debit card experience embedded within the broader uLink ecosystem.

Solution - Website

My Contribution

I contributed to the UX strategy and design of the uLink Card website, including:

• Structuring information architecture
• Designing responsive layouts
• Clarifying benefit hierarchy and product positioning
• Supporting fee transparency presentation
• Aligning messaging with in-app functionality
• Designing conversion pathways toward activation

The website serves as both an education and an acquisition layer, bridging awareness to action.


Outcomes

This project demonstrates:

• Consumer fintech UX execution
• Cross-channel experience alignment
• Regulated financial product design
• Shipped transactional flows
• Collaborative product design in a multi-team environment
