The term electronic banking or e-banking aptly refers to the process of transition of organizations, industries, or common people with banking centers. A group of banks started providing the service of e-banking in 1985, though the concept was formulated in the mid-1970s. After the development of e-banking, customers started seamlessly experiencing the banking process due to the amalgamation of transaction processes and other processes. Indian banks are adopting the latest technologies to serve customers with all the comfort and easy banking process, paving the way for the massive growth of e-banking all over the world, which is also spreading in India. The main objective of the study is consumer awareness and usage of e-banking transactions through mobile phones with special reference to the Dhanbad district of Jharkhand with a sample size of 350. The study suggested providing proper training to customers to use i-banking, building confidence in the minds of customers about the security of their accounts, and providing a platform from where customers can access multiple accounts at the same time without any additional charges. The impact on profit generation due to e-banking has not been considered though it may provide a good area for further investigation.
