Credit cards of many International kinds can be used in restaurants, hotels, petrol stations and shops, but you will have to notify, that company has the right to charge you an extra fee. Not all of them do and you will be notified before making a payment if an extra fee will be charged.
A lot of smaller shops and supermarkets do not accept international credit cards.
