Currency, Euro 

First of all, Finns use Euros like most of the Western European countries. The Euro is divided in 100 cents. The exchange rate between the Euro and other currencies changes every day. For current exchange rates see the following: Current Sell/Buy Courses in Other Currencies  

Note that the 1 and 2 cent coins are not in use. When paying by cash the sum is rounded to the closest 5 cent value. Sorry to disappoint any collectors. 

Banks

Banks are open on weekdays from 10:00AM to 4.30PM. They are closed on Saturdays, Sundays, and public holidays. The word for 'bank' in Finnish is 'pankki'.

ATMs 

A very good network of ATMs exists in all inhabited areas in the whole of Finland. ATMs have instructions in both Finnish and in English so no problem with that. ATMs are marked with yellow signs the say 'OTTO'. 

Credit Cards

The most common credit cards used in Finland are Visa, Mastercard, and Diners. Finns love to pay with bank cards. You do not see checks at all because people feel them old fashioned and too slow to use. Travelers check can be changed in banks and in many hotels too.

One suggestion is to use a Visa card and cash. This duo is 100 percent sure way to pay everywhere.
