A cash register is a mechanical or electronic device used to record and calculate financial transactions, primarily in retail settings. It typically includes a keyboard for entering prices and quantities, a display for showing the transaction details, and a drawer for storing cash and receipts.
Cash registers have a long history, dating back to the late 19th century. Early models were simple mechanical devices that required manual operation. However, modern cash registers are typically electronic and offer a wide range of features, such as automatic calculation of taxes, discounts, and change.
