A point-of-sale (POS) system is a combination of hardware and software that businesses use to process sales transactions. It typically includes a computer or tablet, a cash register, a barcode scanner, and a payment terminal. POS systems help track sales, manage inventory, and generate reports, making it easier for businesses to operate efficiently. These systems are commonly used in various industries, including retail and hospitality. They can accept multiple payment methods, such as credit cards, debit cards, and mobile payments. Modern POS systems often integrate with other business tools, like inventory management and customer relationship management software, enhancing overall productivity.
