Both words mean paper money. Note is the informal British word, often used loosely, as in 'a ten-pound note'. Banknote is more formal and precise, used when discussing the object itself or its authenticity. Note can also mean a short written message, not compared here.

两者在“纸币”这一意义上很接近，但 note 是英式英语中的日常口语说法，banknote 更正式、更通用，常用于书面或强调面额与真伪的场合。这里不比较 note 的“便条、笔记”等其他义项。
