EFT (Electronic Funds Transfer) allows transferring money between bank accounts electronically without paper money changing hands. It is used for payments, refunds, withdrawals, deposits and more. To perform EFT, one must have a bank account and register online for the service. Major banks provide EFT services for customers. Benefits include reduced transaction times and no paperwork, while disadvantages include potential for private information release and lack of human interaction. Security is ensured through unique login credentials and dedicated online gateways.
