Our research confirmed that the dominant part of banking customers use electronic access when managing their personal finances. We found out that there are some differences in the approach of the bank customers in terms of their education. The customers with higher education to a greater extent and more intensively use electronic banking. In the safety area, we did not find any significant differences between banking clients by gender, education and age. The only exception is the finding that clients up to 35 years are significantly more confident in the use of electronic banking through public networks.
