The national currency of Kyrgyzstan is a Som (S, KGS). One sum is 100 tyyins.In circulation there are banknotes in denominations of 1, 5, 10, 50, 100, 200, 500 and 1,000 coms, as well as 1, 10, and 50 tyyina. Coins in the country not in use. 
Som is the only legal bank note in the territory of the Kyrgyz Republic, although the U.S. dollar and Euro are accepted at hotels. Banks are open from 9.00-9.30 to 17.00-17.30 Monday to Friday, weekend - Saturday and Sunday. 
Currency can be exchanged at the offices of banks, exchange offices (usually run around the clock), and in many stores. Not only U.S. dollars and euros, but also the British Pound, the Russian ruble and Kazakh tenge, Uzbek soums, Chinese yuan and other currencies are exchanged. We do recommend to exchange in the capital where the exchange rate is higher rather than in the regions. While exchanging  U.S. dollars it is recommended to have currency in good condition and issued later than 2000th.Credit cards are accepted at most banks and some large hotels in Bishkek .Traveler's checks can be cashed at the offices of major banks, licensed exchange offices and in some large stores of the capital, but the fees are quite high (3-7%). In the provinces, to use non-cash means of payment is almost impossible.
