Although all the member states of the EU are part of the Economic and Monetary Union, not all of them are included in the  “Euro Zone”. That is, all the countries that share a common currency, the Euro.

Nowadays, there are 19 countries (of the total 28 that are part of the EU) that use Euros as their official currency.

If you want to travel to countries like Denmark, UK, Sweden, Romania and some others, you should know that they don’t use Euros and you will need to pay in other currency.

Of course, this will also happen in any other country of the world that  you would want to visit.


It is highly recommended, as a precaution, to take some cash with you when you travel. Credit cards and other digital payment methods are not accepted in all countries. Even in those places where you can usually use those payment methods, you may find some services that you can not pay in that way.

Apart from this, you can encounter technical problems with the credit cards, with your mobile phone network or any other contingency. To have some local cash is always a guarantee.

It is not necessary to take a big amount of cash, only whatever you calculate necessary for a couple of days and some specific mandatory expenses that you will need to cover. Among those expenses you can find, for example when travelling to Vietnam, the visa on arrival, for which you have to pay in USD or VND, and there are no cashiers or exchange offices before the migration control.


In most international airports in countries whose currency is not Euro or Dollar, there are many cashiers and options to buy (or sell when we return) local currency.

Nevertheless, these options are always much more expensive than planning and getting that cash before travelling.

In this case, for example, buying 200 dollars at JFK airport in NY is 14€ more expensive than if we used the official exchange rate for that date:


Buying dollars at the airport



Many travellers finish their trips with outstanding cash. The problem is exactly the same.

This is an example of an exchange office at another NY airport. If you sell 100 dollars which you won’t be using in your home town, the difference between the price that they offer and the official market rate is almost 10%.


Selling 100 dollars at an exchange office.


The traveller would receive 82€ instead of 91€, which would be the corresponding official rate exchange.
