Kyrgyz currency is called Kyrgyz Som (KGS) which is equal 100 tyin. Notes are in denominations of 1000, 500, 200, 100, 50, 20, 10, 5 and 1, and 50, 10 and 1 tyin. You can easily exchange foreign currencies at commercial banks or at street exchange offices in Kyrgyzstan. The US Dollar and Euros are easily convertible. Credit cards are acceptable in some of the larger hotels in Bishkek and can also be used at banks to remove cash from the counter. Traveler's cheques are not always accepted, but some Bishkek banks do accept them, probably the best option to use US Dollars; commission charges are high. Cash is more recommended in Kyrgyzstan.
