The Modern Payment Systems room presents issues related to non-cash money. Payments made with the use of a card, mobile phone, watch or via instant transfer have become an important part of our payment habits. Advanced technical infrastructure and many institutions watch over the efficiency and security of the Polish payment system. Narodowy Bank Polski performs an important role here as regulator and overseer of the systems that guarantee fast and secure transfer of money between people and economic agents. In this room you can, among others, take a look “behind the scenes” at a card payment operation, find out how commercial banks settle accounts with each other, and also learn about the latest trends in the world of modern finance. In addition, anyone who has ever wondered how an ATM works can look inside one of these devices opened up specially for this occasion and check from the technical side the mechanisms used in it for counting and dispensing cash.
