India's banking sector is growing at a fast pace during an early decade. In today’s scenario, it has become one of the most preferred banking destinations in the world. It is almost fifteen years since the Indian banking sector was liberalized and paradigm shift happened in the Indian banking services. All banks have either totally implemented 'Core banking Systems' or halfway through Indian markets provide growth opportunities, which are unlikely to be matched by the mature banking markets around the world. Indian banks are investing heavily in the technologies such as telebanking, mobile banking, net banking, automated teller machine (ATMs), credit cards, debit cards, smart cards, call centers, CRM, data warehousing etc. To convince the management, investors and other stakeholders for this heavy investment in technology, and to achieve customer satisfaction objectives by providing more services to customers .it is desirable to evaluate the impact of computerization on the customer satisfaction and performance of Indian banks in terms of their profitability and productivity. Computerization includes technology advancement, IT, internet and all other things which improve productivity, profitability, ease in doing related work and effective utilization of resources.
