Smart Paying System


What can this do :
- Identify the used currency
- Sell multiple items with one single shop.
- Return items that are not the currency.

This will be useful in adventure maps,in case that the players throw in their required items,the
shop will still return their items safely.

The circuit is easily extendable,just by adding more of the system I used.

If you like it,please diamond it! :)

P.S : This is the first project I was serious on.
