hi there,
Most towns in Poland accept Visa, MasterCard, Cirrus and Maestro cards but cheapest way it's to bring your debit card as they charge less fees than credit cards.
The most
popular currencies are US dollars, euros and UK pounds and you don’t need to present your passport or fill out any forms to exchange money. One thing I would say is to bring bank notes in good condition and without anything written on them as the exchange offices in
Poland can refuse them.
