A Point of Sale Terminal (POS terminal) is a device used by businesses to process sales transactions. It typically includes hardware like a touchscreen, card reader, and printer, allowing customers to pay using cash, credit, or debit cards. POS terminals help streamline the checkout process and can also track sales data. In addition to processing payments, modern POS terminals often come with software that manages inventory, generates sales reports, and tracks customer information. This technology is essential for retailers, restaurants, and other businesses, enhancing efficiency and improving customer service.
