What is FinTech?

FinTech, short for financial technology, merges finance and technology to improve how people and businesses manage money. It powers digital payment apps (Venmo, Cash App), investment platforms (Robinhood), and digital wallets (Apple Pay, Google Pay, PayPal). Beyond these, FinTech innovations include cryptocurrency, robo-advisors, blockchain, and real-time payments, reshaping global financial systems.

Why Do We Need FinTech?

Traditional banking can be slow, complex, and inaccessible to many. FinTech solves these issues by:

• Expanding Financial Access: Millions without bank accounts now use mobile banking. Example: Nubank in Brazil has drastically increased financial inclusion.

• Simplifying Processes: Instant loans, faster payments, and seamless BNPL (Buy-Now-Pay-Later) services like Affirm.

• Personalizing Services: AI-driven finance, such as Lemonade for tailored insurance and Betterment for robo-investing.

FinTech makes financial services faster, cheaper, and more accessible.
