Abstract
The Financial Technology (FinTech) industry has been playing a pivotal role
in driving modern day’s economics, social aspects, technology, and many more areas.
FinTech is majorly inspired, motivated, and empowered by Data Science and Artificial
Intelligence Methodologies (DSAIM). With emerging technology, the smart FinTech
industry has revolutionised economic and financial businesses, service industries, and
systems. The global research communities have made significant progress in smart
FinTech for Banking Tech, Trade Tech, InsurTech, Wealth Tech, Pay Tech, Risk Tech,
Cryptocurrencies, Digital Payment Systems, and Blockchain using DSAIM. In this
review paper, we narrow down the overview of smart financial businesses, their
complex challenges, and the entire smart FinTech ecosystem. The DSAIM enables
smart FinTech and poses some research problems among global academic and
researcher communities.
