Trivia: Where was paper currency first used?
China
Greece
Mesopotamia
Kenya
The correct answer is China
So why is this answer correct? : Paper certificates representing sums of money — known as “flying money” — were first used by wealthy business owners and government officials in China during the Tang Dynasty (618 to 907 CE). But individual notes representing currency that could be exchanged among ordinary people were not introduced until the Song Dynasty, which began in 960 — those were known as “Jiaozi.”
