The aim of this article is to assess the attitudes of senior citizens towards cashless transactions (with a particular emphasis on mobile banking). The literature on the subject presents the dissemination of non-cash payment strategies as an opportunity to reduce the problem of exclusion. Moreover, the researchers who focus on the topic of financial exclusion diagnose self-exclusion within this social strata who do not use modern technologies for current financial activities, additionally pointing to the significant impact of a group of factors: demographic, economic, psychological and social. The considerations are based on a query of the subject literature and an analysis of selected secondary studies. It is noted that there are huge psychological barriers conditioned by a person’s lifestyle. Moreover, the continuous development of and technological progress in the banking sector hinders certain types of banking and deepens the level of financial exclusion of the oldest generation. Increased life expectancy means that the banking sector should not continue to ignore those who are aged 60+. It is necessary to focus CSR strategy, educational activities and product offers on marginalised groups, even if it may seem to be unprofitable for many banking strategies.
