The acceptance of traveller’s cheques and credit cards is not universal in Hungary. The presence of ATMs is increasing in Budapest and other major cities, but in less urban areas availability may be limited.
In general, you can pay with credit cards almost everywhere in the country. Most hotels, restaurants and petrol (US: gas) stations will accept this form of payment. However, smaller shops usually only accept cash. The following credit cards are generally accepted: Eurocard, JCB, Visa, MasterCard, American Express and Diners Club.
Cheques are not commonly used in Hungary. Nevertheless you can cash your cheques at any bank. It is possible to check this bank service on the internet. Travellers Cheques are accepted by banks, bureaux de change and numerous shops. It's recommended to buy Travellers Cheques in Euro or US Dollars.
The main advantage of this method of payment is that you're charged the same fees as with domestic bank transfers for amounts up to €50,000. In order to being able to make such a transaction you need the IBAN (International Bank Account Number) and BIC (Bank Identifier Code) of the beneficiary. Online banking can also be used for Euro bank transfers.
