Cashiers are employed in many different businesses, including supermarkets, department stores, restaurants, and movie theaters. In general, they are responsible for handling money received from customers.
One of the principal tasks of a cashier is operating a cash register. The cash register records all the monetary transactions going into or out of the cashier's workstation. These transactions might involve cash, credit card charges, personal checks, refunds, and exchanges. To assist in inventory control, the cash register often tallies the specific products that are sold. More than 3.3 million cashiers are employed in the United States.
