A POS terminal, or Point of Sale terminal, is a device used by businesses to process customer transactions. It typically includes hardware like a touchscreen, card reader, and printer, allowing customers to pay using cash, credit, or debit cards. These terminals are essential for retail stores, restaurants, and other service providers to manage sales efficiently. In addition to processing payments, POS terminals often come with software that helps track inventory, sales data, and customer information. This integration allows businesses to streamline operations, improve customer service, and make informed decisions based on real-time data.
