The FinTech Explorer is a student-driven guide that presents real-world case studies on how AI, Blockchain, Cloud Computing, and Big Data (ABCD) are transforming the financial sector. Through experiential learning with partners like nursing associations and Indigenous communities, students applied these technologies to tackle urgent challenges. The book not only highlights the practical application of FinTech but also encourages future learners to explore how ABCD can create real, positive societal impact.
