Cash register to keep track of sales and manage transactions. The cash register is a mechanical or electronic device that has a drawer for storing cash and a keyboard or touchscreen for inputting prices and quantities. It also has a display that shows the total amount due and a printer for printing receipts.

When a customer makes a purchase, the shopkeeper enters the price of each item using the keyboard or touchscreen. The cash register then calculates the total amount due by adding up the prices of all the items. The shopkeeper can also apply any discounts or promotions to the total amount.

Once the total amount due is calculated, the shopkeeper collects the payment from the customer and enters the amount received into the cash register. The cash register then calculates the change due to the customer by subtracting the total amount due from the amount received.

The cash register also keeps a record of all transactions, including the date, time, and amount of each sale. This information is useful for the shopkeeper to track sales and inventory, as well as for accounting and tax purposes.

In addition to managing transactions, some cash registers can also perform other tasks, such as generating reports, tracking inventory levels, and managing customer loyalty programs. These features help the shopkeeper to run their business more efficiently and effectively.
