The entire population of Questionnaire was administered to the population of the study but 184 questionnaires were dully returned. Data was analyzed using interferential and descriptive statistics. The inferential statistics involve regression, Analysis of Variance (ANOVA) and multiple regression analysis. A pilot study was also used to test the quality, clarity, time scale and bias of the questionnaire. The paper concluded that cash-less policy will impact positively on the fortunes of banks even though some of the charges are not wholly their revenue.
