E-banking involves using electronic means like the internet or mobile phones to conduct banking transactions instead of visiting branches in person. It offers benefits like convenience, lower costs, and access anywhere there is an internet connection. Common forms of e-banking include ATMs, internet banking, mobile banking, telephone banking, and debit/credit cards. While offering advantages, e-banking also presents risks like security, technology issues, and legal/regulatory concerns that banks and regulators must address. Overall, e-banking is an important development that is changing how banking services are delivered worldwide.
