Money in Ireland is based on a system similar to that of other European countries . So there is no problem spending your money as you see fit. However, beware of a few pitfalls, such as currency changes when you travel to Northern Ireland, or possible bank charges for cash withdrawals!
The Republic of Ireland uses the Euro as its common currency. There is therefore no need to change your money at the airport if you are from European countries using this currency.
This area uses 5€, 10€, 20€, 50€, 100€, 200€ and 500€ notes, as well as 1€, 2€, 50cts, 20cts, 10cts, 5cts, 2cts and 1cts coins.
Similarly, credit cards are fairly well accepted in the Republic of Ireland. Please make sure that your credit card is an international card, otherwise you will not be able to withdraw cash. VISA, Mastercard or American Express cards guarantee you the possibility to make purchases in foreign countries. Do not hesitate to ask your banker beforehand.
Most shops accept these types of payment from 10€, and there are many cash machines in town (less in the countryside).
The monetary system in Northern Ireland is becoming more complicated. The currency used is the pound sterling, because of its official status as a dominion of Great Britain. Therefore, you will need to change your Euros at the nearest exchange office to be able to spend…
This area uses £50, £20, £10, £5 notes as well as £2, £1, 50p, 20p, 10p, 5p, 2p, 1p coins.
As for credit cards, they are used just as much as in the Republic of Ireland. However, be careful when withdrawing money with your card: your bank will charge you a currency conversion fee for each cash withdrawal. Therefore, you should pay by card rather than withdrawing cash from local ATMs.
