CURRENCY
As part of an economic system, we all deal every day with “currency”, that is to say money in all its different forms. It is the means of exchange that makes all our financial transactions possible, starting from our daily purchases.
Our exchange “currency” is Romanian leu (RON). 

Currency is all this
The Euro is the means of exchange, because it allows us to purchase goods and services and it is the unit of account which measures the value of all economic transactions: it fixes the value of what we buy and tells us how much our bank account holds, measuring the value of our savings and our purchasing power. Then it becomes a reserve of value.

For further information
Minca, moneta, monnaie, money, moneda, … many languages for a word that takes its name from the ancient Roman mint, which was located near the temple of Juno Moneta, so called because geese, which were sacred to the goddess, had saved Rome by warning the Romans (“moneo”, which means to warn) of the arrival of the Gaul invaders. 
Today, every country has its own mint, the place where money is coined.. 

Currency in the digital era
Currency has undergone incredible changes for practical reasons and above all because there have always been forgers, thieves and fraudsters. 
The cheque was a brilliant idea, thanks to which for the first time there was no need to physically touch money. It was devised as a safe payment means which served first of all to transfer money more rapidly, with greater guarantees and safeguards. Attention is needed, however, to ensure that there are enough funds and to avoid accepting cheques of dubious provenance.
The electronic card more and more often replaces cash payments, reducing the risk of thefts and ensuring traceability of transactions. But the card can be lost or stolen too. But, unlike cash, it is possible to immediately block its use with a phone call to the issuing bank. Furthermore an alert can be activated to send a message with every transaction. 
Contactless cards allow payment by simply placing the card next to the reader.

Keeping on top of expenses. Spending is easier with electronic means and it is, therefore, very important to closely monitor the actual disposable funds in our current account.
Many cards 
Today “payment cards” made available by banks are quite varied. It is sufficient to contact our bank and ask which is the means that best meets our needs and how much it will cost us.
With credit cards, our account is charged just after the card is used. 
With debit cards, the amounts are charged immediately and our bank can advise us immediately if we go in the red. It simply advises that it is not possible to make the payment.
With prepaid cards, we “load” a certain amount and we can use it until it is exhausted. 
With revolving cards, we “load” a certain sum which is gradually repaid paying an interest rate and immediately reconstituted.
One tool for all purposes. Today, digitalisation allows to integrate different functions on the same device. For example, it is possible to pay directly with a smartphone. But the future of “currency” is in biometrics: applications that allow to payment with a digital print!

Exchanges in the digital era
Dematerialised currency has allowed to change the way we make purchases: from home, on the internet, with continuously evolving e-commerce.
The advantages are in the costs (often lower compared with a physical shop), in the possibility of comparing many different offers, in the opportunity to receive the product at home, with the possibility to return it if it is not as expected.
To address the risks of theft of data that virtual exchanges posed at the start, today online payments are protected by sophisticated security systems put in place by banks.
