New research shows 40% of the Irish population haven't heard of the digital euro, a planned digital version of physical euro bank notes and coins.
The survey carried out by management and technology consultancy BearingPoint captured the views of people across seven countries in Europe.
The digital euro has entered a two-year preparation phase which will lay the foundations for potentially issuing the digital euro across Europe.
According to the European Central Bank, it is not intended to replace cash but to complement it.
On average, around 26% of respondents expect the digital euro to be used as a supplement to existing payment methods.
However, just 8% of Irish respondents believe that the digital euro will complement existing payment methods - indicating the lowest confidence compared to other countries.
Christian Bruck, Partner and Payments Expert at BearingPoint said cash is by far the most popular payment method in Europe.
"It is so high partly due to the fact that in uncertain times, cash is perceived as particularly familiar and secure," he explained.
"It is interesting to note that, despite the differences in today's use of cash, an average of one in five people would use the digital euro several times a week.
"This underlines the potential of the digital euro," he added.
Respondents to the survey said it would be important that the digital euro is accepted everywhere, around the clock and is free of charge.
