The ability to apply state-of-the-art Internet of Things (IoT) technology to extract customer insights through analytics by shaping the information into consumables for other connected systems is creating a lot of opportunities for banking and financial services. This paper presents an architecture based on Internet of Things for banking and finance sector by managing, mobile, household devices, wearable sensors and other sensing devices for various applications including retail banking, insurance, and investments. We have presented a case study of different banking applications flow with IoT-intelligence by analyzing users' data. In addition, we have a mapping of the proposed architecture onto the various applications of banks and financial services.
