FinTech refers to any technology that helps financial institutions or consumers deliver financial services in novel and more convenient ways. Historically, banking involved long queues and paperwork, but FinTech now allows for real-time money tracking and transfers through mobile apps. Major FinTech developments over time include the credit card in the 1950s, online brokerages in the 1980s, and digital payment systems like Google Pay in the 2010s. Both opportunities and challenges exist with FinTech, such as improved convenience but also increased risks of hacking and data theft that require strong cybersecurity from financial institutions. The future of FinTech is expected to increasingly incorporate artificial intelligence and machine learning.
