Payment processing for a quarter of Iceland's card acquiring. Merchant portals, onboarding, POS flows.
straumur.is: one solution for every way a merchant gets paid.
Straumur is Kvika's payment processing subsidiary, serving roughly 25% of Iceland's acquiring market. I worked on merchant-facing web experiences across POS, e-commerce, and payment infrastructure.
The problem
Financial products demand trust, clarity, and reliability. Merchant flows span onboarding, service portals, and operational tooling — each with different user mental models but one brand system.
The approach
I treated each flow as part of a coherent product language: strong hierarchy, restrained motion, and frontend patterns that made complex payment concepts scannable for non-technical merchants.
