Topika was asked to come up with a design for the interface of an Android tablet app for a mobile payments system to be launched in East Africa. Specifically, they were asked to develop mockups for the screens an agent would see when taking cash deposits from new or existing users. They invited me to work with them thanks to my knowledge of both mobile apps and money transfer systems. Together we took our initial brief, challenged some unrealistic assumptions, and came up with a simple, efficient app design and workflow. You can read more on the Topika site about the project.
