A POS 시스템 (Point of Sale system) is a combination of hardware and software that allows businesses to process sales transactions. It typically includes a computer, cash register, barcode scanner, and receipt printer. This system helps retailers and restaurants manage sales, track inventory, and generate reports. In addition to processing payments, a POS 시스템 can also handle customer data, manage employee schedules, and integrate with other business tools. By streamlining operations, it enhances efficiency and improves the overall customer experience, making it an essential tool for many businesses.
