In short

What if you could open a bank account, enroll your child in school, or buy coffee — all with just your face?


For a national innovation event, I designed five public service journeys using facial biometrics as the only access point. From scope definition to high-fidelity prototyping, I collaborated closely with PMs, developers, and marketing to bring these experiences to life in real, interactive totems.


This project changed how people (and I) see digital identity: not just as data, but as something personal, powerful, and full of possibility.

Context

This project was part of a temporary initiative for a national event focused on the future of digital citizenship in Brazil. The main goal was to imagine a world where facial biometrics is the only key needed to access public and private services, like opening a bank account, enrolling children in school, or even buying a coffee.


I joined the team to help define the scope of the project and ideate the user flows and screens for different journeys. Together with Product Managers, developers and QA, we created interactive prototypes to explore how these services could feel safe, simple, and accessible for all types of users.


The event had high engagement from the participants, including members from the highest levels of the Brazilian government. People tested the experiences several times, but the most used journey was the facial recognition coffee purchase, which had huge success in sales and became the highlight of the event.

Challenge

What if, in the future, facial biometrics was the only thing needed to access any service?

Our challenge was to design journeys that felt safe, inclusive, and easy to use: no passwords, no documents, just your face. We had to think about trust, accessibility for diverse users, and how to create smooth experiences, even in emotional or complex situations.


As a Product Designer, I helped define the project scope, map user flows, and create high-fidelity prototypes. I also joined daily team alignments to support fast decisions and solve issues quickly.


This project was a mix of creative thinking and real-world responsibility, focused not only on future technology, but on future trust.

Design proccess

The design process was built in collaboration with different teams and roles. Each step helped shape the journeys into real and functional experiences:

  • Flows and architecture: In the beginning, the design managers worked closely with stakeholders to define the main scope and structure that all journeys should follow. This helped guide the design direction from the start.

  • Ideation and wireframes: Based on the architecture, I created wireframes to explore the key screens of each journey. During this step, I collaborated with design managers, product managers, and developers to co-create important interactions and define specific moments in each flow.

  • Content and interface texts: I worked together with the marketing team to define the right words for the interface. Our goal was to make sure the copy was not only easy to understand, but also aligned with the tone and goals of the event.

  • Final prototype: After several refinements and team discussions, we created the final versions of each journey. This included visual polish and the production of clickable prototypes to simulate real user interaction.

  • Handoff to developers: Once the designs were ready, I supported the handoff to the development team, helping to answer questions and make refinements when needed. This step was important to keep the design quality during the implementation process.

Solutions

To bring the vision of facial biometrics into real user experiences, we designed five key journeys. All of them were based on the same foundation: scanning the new National ID document and using facial recognition as the main way to access services. Each journey was created to explore a different moment in everyday life, showing how biometric technology can simplify important tasks:


  1. Banking Journey: Open a bank account quickly and safely

  2. Education Journey: Enroll your child in school without physical documents

  3. Health Journey: Book a medical appointment using only your face

  4. Maternity Journey: Register a newborn child with automatic connection to their parent

  5. Coffee Journey: Buy coffee at a shop using just facial biometrics


Each flow was designed with clear structure, easy navigation, and human-centered decisions. Below, you’ll find examples of the architecture for two of these journeys.

High fidelity screens

In the final phase, we transformed the wireframes into high-fidelity prototypes to simulate real user interactions. During this step, we made important design decisions to support both the visual identity of the event and the unique interface needs of a totem (touchscreen terminal).

Colors

Each journey started with a cover screen using the company’s branding and a specific color that matched the design of its physical stand, created by the marketing team. All color choices were tested and approved to meet visual accessibility standards (contrast and readability).

  • Banking: Green

  • Education: Orange

  • Maternity: Red

  • Health: Blue

  • Coffee: Black


This color system helped participants easily recognize and navigate between different stands during the event.

Components

Designing for a totem was different from designing a mobile app. We had to adjust our components to work well on larger screens and for quick, public interactions. Some key decisions were: Large selection buttons, easy to tap and read. Action buttons always placed at the bottom of the screen for consistency. Strong visual feedback (color changes, highlights, confirmations) to guide users clearly through each step. Below, you can see a little video showcasing a selection button in action.

Working with a totem interface also required thinking at a completely different scale. While mobile interfaces typically work within a space of around 390×844 pixels, the totem interface operated in a space nearly three times larger, both in pixel dimensions and physical size. This meant reconsidering element proportions, spacing, and visibility from a standing distance — especially for users who may not interact up close. Working at this scale challenged me to think beyond familiar patterns and brought new depth to my understanding of interface design.

These choices helped make the experience simple, intuitive, and accessible — even for people who were using the system for the first time.

Impact and takeaways

Seeing people imagine themselves in a fully digital world, where services are accessed with their unique personal data, like a face or a fingerprint, was truly rewarding.


This project gave me a deeper understanding of digital identity and the future of service design. It also showed how important it is to design for trust, especially when working with something as personal as biometric data.


One of my key takeaways was realizing that design should not be limited to mobile or desktop interfaces. Creating user journeys for a large-format interface like a totem expanded my perspective and enriched my experience with non-traditional digital environments.


More than just an experiment, this was an opportunity to change how people see their own data not just as information, but as something powerful, personal, and full of possibility.
