Fintech refers to new financial technology that seeks to improve and automate delivery of financial services. The Global Fintech Adoption Index explores how fintech has expanded globally. Fintech has evolved over three eras - infrastructure (1886-1967), banks (1967-2008), and startups (2008-onward). Fintech serves business-to-business, business-to-consumer, and consumer-to-consumer customers. While fintech provides benefits like real-time data and easier payments, it also presents risks like security issues and lack of uniform standards.
