SuperDigital
SuperDigital was Santander's prepaid digital account for the underbanked in Latin America. I designed the Pix MVP, bringing Brazil's instant-payment system into the app: registering keys, paying, and receiving money in seconds.
Challenge
Pix was new, it was mandated, and it was about to become the default way Brazilians move money. For SuperDigital's audience, many of them new to formal banking, it had to feel obvious the first time: no jargon, no fear of sending to the wrong person, and a clear confirmation at every step.
Approach
I designed the full Pix surface for Android around one hub: manage your keys (CPF, email, phone, random), pay by key, scan a QR, or copy-and-paste, receive with a shareable static QR, schedule a Pix for a future date, and track your limits. Every transfer screen leads with who you're paying and how much, keypad-first, with the balance always in view so nobody overshoots. The schedule history shows each payment's status (paid, scheduled, processing, failed) at a glance.
Outcome
Shipped as SuperDigital's Pix MVP (key registration, pay, receive, and QR flows) inside an app already serving millions across the region.
