Bab 275: Hikaru's plan...

Hikaru nodded: "Yes, I intend to integrate that function into the ID card so that people can easily reserve it as a currency for transactions."

Yes, Hikaru thinks that the simpler it is to move, trade, and store money, the easier it will be for the economy to thrive.

He remembered the Earth's history, during which it issued many coins made from various materials.

Most of them, however, were made of metal and were cast into round or square coins. However, they all have the disadvantage of being difficult to move and exchange.

That's right, think of yourself as a rich merchant carrying a lot of money. which may weigh up to 100 kg or even a tonne, so how can you transport them safely?

If it is paper money, it can easily be damaged during storage. For example, they can be mouldy, wet, torn, etc.

So, in the 21st century, the Master Card became popular because people only needed one card to pay for things or change it into cash.
