In the new digital age, the use of electronic money has become more and more in the daily life of people. If we stop to think, many of us, we see as with the passage of time, we make less use of cash. We pay the bills; we buy clothes, plane tickets, tickets for concerts, and countless other things, over the internet. Even when we go out on the street, we use the credit or debit card in most shops as a means of payment. In the United States, some economist experts even dare predict the death of cash by 2043. Others are more skeptical and even refuse to do so.
