Manage my debit card

I led the end-to-end redesign of our debit card management experience to support over 400K cards transitioning from Visa to Mastercard.

1. Discovery

User survey

Analyzed user survey results to understand card management behaviors.

Identified most-valued actions: lock card, add to digital wallet, and activate card.

Used insights to prioritize key tasks and shape UI hierarchy accordingly.

Competitive analysis

Reviewed 13+ competitors to benchmark card management features.

Identified common UX patterns and industry standards.

Uncovered gaps and opportunities to improve and differentiate our experience.

Behavioral insights

Reviewed Glassbox session recordings to observe real user behavior in current card flows.

‍Identified and addressed 3 usability issues:

1. Unclear verbiage and copy


2. Poor touch accessibility

3. False affordances

Design strategy

Hosted an impact/effort matrix workshop to align on MVP scope and prioritize key features.

Integrated business goals into the design strategy.

Strategically positioned high-value actions to support both user needs and business initiatives.

3. Outcome & Impact

25-35% reduction in user friction

Restructured the mobile interface by eliminating an unnecessary page and reducing interactions by 2 taps per task. This simplification led to faster task completion, based on tap path analysis and decreased session lengths post-launch.

30-50% reduction in usability issues

Addressed major usability blockers uncovered in session replays, including small tap targets, poor keyboard navigation, and misleading visual cues. Fixing these issues contributed to a decrease in user error rates and drop-offs across key flows, improving both accessibility and overall satisfaction.

Improved activation flow

Redesigned the card activation journey with clearer step-by-step guidance and updated banner copy. Previously, 40% of users clicked the banner expecting to activate without their card in hand. After clarifying requirements in the banner, we saw a reduction in misclicks and user confusion, significantly improving activation success rates.

Modernized visual design

Refreshed the UI using modern, platform-native components and a clear visual hierarchy. This not only improved usability and task scannability but also set a scalable foundation for future features, aligning with our broader app-wide modernization strategy.
