Fintech : Digital finance platforms and embedded financial systems
Financial technology, often referred to as Fintech, is the combination of finance, software, data, and digital experiences. The integration of all these elements in financial activities during the last decade has transformed the way individuals and businesses pay, borrow, invest, insure, and manage money.
From real-time payments and digital wallets to AI-powered credit scoring and embedded finance, the use of fintech platforms is reshaping the financial infrastructure worldwide. The modern fintech activities are different from traditional financial systems, which were built on rigid, legacy infrastructure. Today, all these activities are API-driven, cloud-native, and data-intensive.
This guide is aimed at letting technology leaders, product managers, architects, and business decision-makers understand the working of fintech systems, the role of data and AI, and where the financial industry is shifting.
