A banknote is a type of paper currency issued by a government or central bank, used as a medium of exchange for goods and services. It typically features various security features, such as watermarks and holograms, to prevent counterfeiting. Banknotes come in different denominations, allowing for transactions of varying values. Banknotes are part of a broader monetary system that includes coins and digital currencies. They are often printed with images of historical figures, national symbols, or landmarks, reflecting the culture and heritage of a country. The value of a banknote is determined by the trust in the issuing authority, such as a central bank.
