Currencies in practice

The banking sector believes that individuals use different currencies interchangeably and that they use them only to pay for purchases. In reality, individuals do not use all currencies in the same way, even though these currencies have exactly the same financial value. These various practices deserve to be understood to be better accompanied.



We use many different forms of money in our lives: banknotes, coins, bank cards, restaurant vouchers; etc. We do not randomly choose them, but depending on who we are, what they say about us, and what we expect from the transaction. In a current world where money is being increasingly dematerialized, characterized by a predominance of abstract monetary forms, our goal is to understand how the choice and use of currencies are made. Money control and management of social relations are the key issues that producers of these forms of money will have to address, in order to ensure their adoption, and therefore their success.

«Between card and check, I prefer the second option. But the check is less frequently accepted. The reason I prefer check is that the card has a virtual side that bothers me. I feel like I do not pay anything! On the other side, writing the amount on the check in numbers and letters, forces me to retain that I have paid such a sum [...] it gives me the feeling of having control of my expenses. »


The field survey was conducted through semi-directive interviews with 18 people. The knowledge of anthropology and sociology have been mobilized to understand and analyze the various practices relating to currencies.
