Preferably use MasterCard and Visa cards in Russia. They are accepted by all stores and ATMs. Other types of cards are not popular, so you should ask: Принимаете карты American Express? (Do you accept American Express cards?).

Surprise! Sometimes, even when you are paying a small amount with a card, you may be asked to show a документ (identity document) . The ID that is suitable in all situations in Russia is your паспорт (passport).
