A Point of Service (POS) is a system used by businesses to process transactions at the location where a customer makes a purchase. It typically includes hardware like a cash register or card reader, along with software that manages sales, inventory, and customer data. POS systems streamline the checkout process, making it faster and more efficient for both customers and staff. In addition to processing payments, a POS can also provide valuable insights into sales trends and customer preferences. Many modern POS systems integrate with other business tools, such as inventory management and customer relationship management (CRM) software, enhancing overall operational efficiency.
