Today you tap a card or scan a QR code at the kopitiam and — ping! — lunch is paid for.
But money was invented. Somebody had to think it up! Long, long ago there were no coins, no notes, no cards. So how did people get what they needed?
Let's travel back in time and find out. Ready? 🚀
Swapping one thing for another is called barter. A fisherman with too many fish could give some to a farmer, and get rice back. No money needed!
Your turn: make a barter trade
Ah Kong the fisherman has fish 🐟. Tap the person who actually wants fish.
See? Barter only works when both people want what the other one has. That is the tricky part…
What if nobody wants your fish? Then you must swap, and swap, and swap again until you finally reach the thing you want. Try it!
Goal: Ah Kong wants a 🏺 clay pot.
Phew! Three trades just to get one pot. Now imagine doing that every single day. People needed a better idea — something everybody would accept.
People picked one special item that everybody agreed to take — even if they didn't need it themselves. In China people used cowrie shells. In other places: salt, beads, even cocoa beans!
Be the money-chooser!
Good money must last a long time, be easy to carry, and be hard to find everywhere (or it wouldn't feel special). Tap the best choice.
Fun fact: the Chinese character for money and value, 貝 (bèi), is a picture of a shell! 🐚
About 2,600 years ago in Lydia (today's Türkiye), rulers started stamping lumps of metal into coins. Every coin of the same type weighed the same, so nobody had to argue about it. The king's picture on it meant: this is real.
Work the royal mint 🔨
Tap the hammer to stamp coins. Make exactly 5 identical coins for the king.
Because every coin was the same, people could finally say “this pot costs 3 coins” — a real price! Counting and saving became easy.
Coins were great — until you needed a lot of them. A bag of 1,000 coins is heavy! In China, over 1,000 years ago, people left their coins safely with a merchant and carried a paper note instead. The note was a promise: “bring this back and get your coins.”
Which is easier to carry?
