Coca-Cola Smart Fridge (Brasal Refrigerantes)

Brasal Refrigerantes, the largest Coca-Cola distributor in Brasília, introduced smart fridges into residential condominiums to modernize the vending experience. These connected fridges allowed users to unlock, select, and pay for products directly through an app, but the first version wasn’t delivering the convenience it promised.

‍

Users struggled with unstable connections, poor feedback during the purchase process, and security flaws that allowed the system to be bypassed. What should’ve been a quick, frictionless interaction often turned into frustration and operational headaches.

‍

"The result: low adoption rates, customer frustration, and recurring inventory losses."

‍

My role was to redesign the Coca-Cola Smart Fridge experience end to end, improving usability, expanding payment methods, and restoring user trust in the product’s reliability.

We rebuilt the entire user experience from the ground up, focusing on simplicity, trust, and technical consistency.

The new flow guided users more intuitively from unlocking the fridge to confirming payment, reducing time and errors at every step. We also expanded payment options beyond credit cards — integrating digital wallets, Pix, and loyalty points, which made the product more inclusive for different customer profiles.

‍

- Expanded Payment Options: Added digital wallets, Pix, and loyalty points to make payments faster and more accessible.

- Enhanced Security: Implemented real-time tracking and automatic locking after each purchase to prevent misuse.

- Improved User Journey: Simplified purchase flow, clearer feedback, and smoother transitions between steps.

- Technical Optimizations: Reduced crashes by 80%, improved QR responsiveness, and stabilized API communication.

‍

We also introduced real-time alerts for restocking and promotional notifications, transforming what used to be a purely transactional experience into an interactive product ecosystem.

‍

"The redesign turned the Smart Fridge app into a faster, safer, and more engaging experience, one users now actually enjoy using."

After the redesign, usability tests and operational data revealed a significant improvement across all key metrics.

‍

Increased Payment Flexibility: +60% faster checkout and improved completion rates.

Enhanced Security: Zero security breaches reported after the new tracking system was implemented.

Better User Engagement: Noticeable growth in engagement, with more users returning for repeat purchases.

Optimized Performance: 75% fewer crashes and higher stability on Android and iOS.

‍

Feedback from users highlighted trust, clarity, and convenience as the main improvements. Operationally, Brasal reported smoother inventory control, fewer support requests, and measurable revenue growth from recurring users.

"The project not only solved the original pain points, it repositioned the Smart Fridge as a reliable, modern extension of Coca-Cola’s brand experience."
