A POS system, or Point of Sale system, is a combination of hardware and software that businesses use to process sales transactions. It typically includes a cash register, a computer, and a software application that tracks sales, inventory, and customer data. This system allows businesses to efficiently manage sales and streamline operations. In addition to processing payments, a POS system can generate reports, manage employee schedules, and track customer preferences. Many modern systems also support various payment methods, including credit cards, mobile payments, and digital wallets, making transactions faster and more convenient for both customers and businesses.
