Cashier's paper means that when the cashier checks out in shopping malls, supermarkets and other shopping places, he will input the information such as the purchase quantity and unit price of the goods into the computer system, and then the system will automatically generate a list and print it on paper. This paper is a cashier's check.

The function of cashier paper is mainly to facilitate customers to check the name, quantity, unit price, total price and other information of purchased goods, and to serve as a voucher when returning goods, so as to facilitate the confirmation of goods and prices and avoid misunderstandings or disputes.

In addition, some shopping malls and supermarkets will also print consumption points, coupons and other information on cashier paper, so that customers can enjoy more discounts and discounts when shopping next time. Therefore, cashier paper is not only a necessary settlement tool when shopping, but also an important reference information and potential source of welfare in the shopping process.
