Point of sale

Point of sale (POS) refers to the place where you buy things from a store or a shop. It is where the cashier or the shopkeeper makes the transaction happen by scanning or punching in the items that you want to buy and telling you how much you need to pay.

A POS system is the machine or the computer that the cashier uses to do all of these things. It helps the shopkeeper keep track of the inventory or the items they have in the store and how much money they have earned from selling these items.

Think of it like playing pretend store with your friends. You have a toy cash register where you can press buttons and make sounds just like a real store. The POS system is like that, but it is more advanced and helps the store keep track of all the real money they have made.
