A cashier enters customers' purchases in a point of sale system, commonly called a cash register. A cashier accepts payment from customers in cash, check or credit card. A cashier must process every transaction accurately so that the cash register balances at the end of her shift.
A cashier also verifies customer information. This often is required when a customer pays for a purchase by check or credit card and must show proof of identification. A cashier also must process discounts offered by the business. Most businesses place the cash register near the entrance, which makes the cashier the first person customers see when they enter the establishment. This makes customer service skills an essential part of the job.
