What is exact change meaning?

Exact change refers to the exact amount of money required to make a payment, without any change being needed. For example, if an item costs $1.50 and you pay with two one-dollar bills, you would have exact change. This can be important in situations where cashiers may not have access to a lot of change, or when paying for something like a parking meter that only accepts exact change. It can also help avoid confusion or errors in transactions.
