Chapitre 681: Vending Machines!

Tim posted down all the facts about money within the Pyno continent, and soon... his eyes quickly lit up.

Now, he had a rough idea of where Landon was going.

But he still decided to wait for Landon's response first.

"Alright... so, how does the machine knows to send back the fakes and keep track of what people paid in?

Well... since you roughly understand how the machine handles paper money, then let's focus on coins.

Firstly, this machine will be able to decipher coins with pinpoint accuracy.

Once a coin drops in, light sensors will measure its size.

And following that, electromagnets will detect the metal type... which will identify the coins in split seconds.

So if someone drops anything other than gold, copper or silver, the machine will reject it.

And if the size isn't within the specified range, the machine will also reject it as well and sort it out into columns.
