SuperDigital
SuperDigital was Santander's prepaid digital account for the underbanked in Latin America. I designed the Pix MVP — bringing Brazil's instant-payment rails into the app: registering keys, paying, and receiving money in seconds.
Challenge
Pix was new, mandated, and 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 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, QR scan, or copy-and-paste, receive with a shareable static QR, schedule Pix for a future date, and track limits. Every transfer screen leads with who you're paying and how much — keypad-first, balance always in view so nobody overshoots — and the schedule history shows per-payment 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.
