The Euro
As you know, the currency in Ireland is called the euro. You should start familiarizing yourself with the conversion rate of the dollar to the euro and vice versa. You may also want to start familiarizing yourself with the banknotes and coins (and what they look like) to avoid standing or sitting in public spaces trying to figure out how much money you have.
Also, remember the euro is the currency in Ireland and the majority of Europe with the exception of the UK. If you are traveling to another country during your visit, the euro may not be used there, so be sure to research local currencies before you travel.
Credit or Debit Cards
A debit card allows you to withdraw money from your bank account in the United States in the currency of your host county, which serves as an extremely convenient way of exchanging money while abroad. We recommend that you keep a copy of your card's contact information somewhere safe, so that you have it on hand in the event that you misplace it.
Many debit/credit cards can be used in ATM machines abroad, but be aware of the local and international charges this can incur. Visa and MasterCard are more widely accepted worldwide than are other cards like American Express and Discover.
Also, it is becoming more popular in Europe for people to use pin and chip cards (instead of the traditional swipe card). If you have a chance to upgrade your card to a chip, we recommend doing so before traveling abroad.
Be aware of any foreign transaction fees your bank likely charges for debit / credit card use abroad, as 3% per transaction is not uncommon. Set up online banking for these accounts so you can monitor your expenses and associated fees as they get translated into dollars. If your card is already fairly worn, consider getting a new one before departure.
Card Safety
Before traveling, be sure to notify your bank and/or card companies that you will be traveling abroad to avoid your card usage being frozen. You should also ask if there is a transaction limit or a daily limit set on the card and make changes on those limits if appropriate.
If your card is lost or stolen, cancel it as soon as possible. Before you leave the States, write down the account numbers of these cards as well as the customer service numbers of the bank and/or card companies.
Make copies of this information for yourself as well as a family member. Store the information in a safe place separate from where you store the cards themselves.
Cash
You may need cash in smaller towns or when splitting costs with friends. Check exchange rates before you change money from USD to the euro, and be aware that airports, hotels and train stations will often charge a higher rate of commission than a bank (the larger, the better). Also, do not carry more cash than you can reasonably afford to lose.
