Almost every item that you purchase in a shop has a barcode on it,containing details about the product ,the manufacturer and the country of origin.The barcode details are scanned into the system by a laser scanner on the till,and are sent to the store’s central computer system.This computer system contains the current price of the product in the database,which is then sent to the Electronic point of Sale till ( EPOS),which processes and prints the customer’s itemised bill.
