In 2011 Estonia joined the common European currency, good news for all of the tourists who visit Estonia from countries that already use the Euro. If you happen to come from a country that does not use the Euro, it should also be easier to change your money before you arrive as most banks around the world stock this currency. Standard Euro denominations are legal tender, however you may find it difficult to pay with any bills over 50. All ATMs operate on international systems. Credit cards are easy to use - major hotels, most restaurants and a pretty much all downtown shops accept Visa, Mastercard and EC. American Express, Globus and Diner's Club are less common.
