Fintech uses modern technology to deliver financial services quickly, conveniently, and mostly online, while traditional banking relies on established banking systems, physical branches, and broader regulated financial services.

Mobile banking works by connecting your banking app to your bank's secure servers over the internet. After you log in securely (using a password, PIN, or biometrics), you can access your account, check balances, transfer money, pay bills, and manage transactions in real time.

Cryptocurrencies work by using blockchain technology to securely record and verify transactions on a decentralized network without the need for a central bank or intermediary.
