The growing competitiveness in the modern world of finance makes it necessary to recognise education as one of the major elements in marketing communication between banks and their customers. It is of particular importance in the case of the Polish finance sector where technological innovations as well as social and economic changes are taking place very fast. Domestic financial institutions have at their disposal various tools which can be employed in educational strategies, starting from advertising media, through public relations to modern customer service points specialised in consulting services. The internet offers banks a particularly wide variety of possibilities as regards consumer education on financial market; however these possibilities have not been fully recognised yet. Agents in our country seem rather reluctant to give up a popular and sometimes even quite successful "strategy" of lack of marketing reliability, which is, in fact, the opposite of educational philosophy. Yet, in the last few years banks have made huge progress in expanding customers' knowledge and understanding of the modern economy and technology. The methods and tools are constantly changing. More and more training initiatives are being undertaken by financial institutions. This new approach seems a necessary step for any bank to achieve success. An educated client can generate more value for a financial institution than a client lacking familiarity with the modern electronic banking environment.
