The Kyrgyz currency is the som. Bank notes come in 20, 50, 100, 200, 500 and 1,000 som denominations. Coins are 1, 3, 5 and 10 som denominations.
There are ATMS in Bishkek, Osh, Karakol and other big towns in Kyrgyzstan that accept AMERICAN EXPRESS, VISA and MASTERCARD.
Other towns and villages have ATMs, but usually only accept VISA cards.
You can exchange U.S. Dollars, Euros, Rubles or Tenge in Bishkek and Osh. Smaller towns or villages rarely are able to provide such services.
