Opportunity and problem

Dinero Express (DEX) Banco Azteca’s (is one of the largest banks in Central America) money movement division. They were falling behind and not attracting younger generation of users with their brick and mortar model. DEX believed customer satisfaction and brand loyalty were affected by the limited store infrastructure; they wanted digital to simply extend as a store. To build a solid strategy for this financial institution, we needed to understand users (half of them unbanked) and business needs in this new market.

My role and responsibilities

I worked in a small team with creatives, researchers and strategists. I led the interaction design track, participating in research phase, owning product concepts and detailed designs.

Process highlights:

• Research: As soon as we were in the field, we discovered the initial hypothesis was off. People did not care about the long lines but accepted them. They primarily cared about the money sent getting to their families/friends fast and securely. There was major mistrust in institutions. Based on new insights we emphasized the emotional and social aspects of money in the strategy, aimed to build trust with the users at every moment of the experience.

• Bringing insights to the product design: We proposed a digital personal wallet that emphasized the safety of users’ balance and clearly showed successful money movement with family/friends. I explored various models from skeuomorphic wallets to utilitarian designs that focused solely on quick actions. We went for a concept that would feel familiar, showing your money (users’ balance) upfront on home view and your actions (send money, withdraw, etc.) stacked at the bottom (resembling cards in a physical wallet). The latest money movement functioned as a link to a detailed feed. Every detail, from structural design to animations, tied back to user insights.
