Cash register
After the cashier has scanned all of the goods, he or she will ask the customer for payment. If the customer is paying by cash, the customer gives the cashier money, which the cashier will count to find out how much the customer is paying. He or she will then enter the amount into the cash register, which will open the cash drawer. Inside the drawer, there are different places to put each type of bill and coin (for example, all the 1-dollar bills go in one part, and all the 25 cent coins go in another part). The cashier puts the bills and coins from the customer into the right places in the drawer, and takes out bills and coins that add up to the amount of change that the customer is supposed to get. The cashier closes the drawer and gives the change and receipt to the customer.
