Circular Note is a type of financial instrument that was widely used in the past. However, the term is not in common use these days. Instead of Circular Note, it is more common to use other terms like traveler's check, bank draft, money order or cashier's cheque. These financial instruments are still widely used for international money transfer or for sending payments. With the growth of online banking, digital wallets and other modern payment methods, the use of Circular Note has diminished. While Circular Note is now a mostly obsolete term, other synonyms that replace it are still commonly used in the financial world.
