Cashiers typically do the following:

• Greet customers
• Scan or register customers' purchases
• Accept payments from customers and give change and receipts
• Bag or wrap customers' purchases
• Process returns and exchanges of merchandise
• Answer customers' questions and provide information about store policies
• Help customers sign up for store rewards programs or credit cards
• Count the money in their register at the beginning and end of each shift

In some establishments, cashiers have to check the age of their customers when selling age-restricted products, such as alcohol and tobacco. Some cashiers may have duties not directly related to sales and customer service, such as mopping floors, taking out the trash, and other custodial tasks. Others may stock shelves or mark prices on items.

Cashiers use scanners, registers, or calculators to process payments and returns or exchanges of merchandise.
