Full Form of ETK
What is ETK?
An Electronic Transaction Key (ETK) is a security device or software token used in Indian banking to authenticate and authorize high-value or sensitive online transactions. It typically generates a one-time password (OTP) or a dynamic code that must be entered during a transaction, adding an extra layer of security beyond a standard password or PIN. In India, ETKs are commonly issued by banks to corporate customers, merchants, and individual account holders for net banking, fund transfers above a certain threshold, and digital payment platforms. They are used in conjunction with the Reserve Bank of India’s two-factor authentication mandate to prevent fraud and unauthorized access. ETKs can be hardware-based (like a USB token) or software-based (mobile app), and are widely adopted in public and private sector banks across the country. For students preparing for banking exams (e.g., IBPS, SBI PO), understanding ETK is important as it frequently appears in questions on digital banking security and regulatory compliance. The use of ETKs has significantly reduced cyber fraud in Indian banking, making them a critical tool in the country’s push toward secure digital finance.
