The official currency is the Euro (EUR). Most hotels and restaurants in Riga accept credit cards, but outside of the capital credit cards are not widely accepted and credit card fraud can be a problem at smaller institutions. Foreign currency can be exchanged at any bank, at money change kiosks and at some hotels. Note that an extra fee will be charged to exchange US dollars that are torn or marked in any way. Most banks are closed on Saturdays and Sundays. ATMs are available in the larger cities.
