The core of a POS system lies in the tight integration of its software and hardware. The hardware typically includes a cash register, printer, barcode scanner, and cash drawer, while the software encompasses the operating system, sales management software, and database. When a customer selects items, the cashier quickly scans the product barcodes with a barcode scanner. The POS system immediately identifies the product information, including price and inventory, and automatically calculates the total price. After the customer pays, the system updates the inventory record and prints a sales receipt, completing the entire transaction process.
