Introduction

Carteira bB was designed to help millions of Brazilians—many of whom were using digital banking for the first time—manage their money simply and safely. I led the redesign of the digital wallet during a moment of deep social and economic change, with one clear goal: to make financial services truly accessible.

1. Understanding a Complex Social Context

During a period of economic vulnerability in Brazil, many users relied on government aid and faced barriers, including fear of digital transactions and difficulty navigating the app. Research revealed the need for clarity, guidance, and trust.

2. Designing for Simplicity and Confidence

We reorganized key flows—checking balances, receiving aid, paying bills, transferring money—using accessible language, visual clarity, and inclusive design principles. The focus was on reducing friction for low-literacy users.

3. Improving Adoption Through Trust and Transparency

We added clearer feedback, transparent statuses, and step-by-step confirmations to reduce uncertainty. This improved confidence, increased adoption, and lowered support demand.
