This article illustrates a concrete application scenario where the power of IoT is harnessed to solve a concrete problem with a practically immediate return on investment. In particular, it shows an IoT-based system, developed to implement a financial management system for fuel stations in Africa. The problem seems to be local to Africa, but building this IoT system has three key learnings that are global in nature. The IoT system aspires to solve a regional problem. It connects remote, poor connectivity locations. It motivates the formation of a creative secure deployment.
