The warehouse of today would be unthinkable without the barcode. The barcode label on each item provides specific information about the product, which can be transferred to a computer system. This makes it possible to locate the item's position in the warehouse and find it again. By using automated technology, such as barcode scanners and RFID (radio frequency identification), warehouse inventory and product flow can be efficiently managed. Combined with modern IT systems, barcodes enable warehouse staff to track and trace all items in the warehouse at any given time and usually in real time.
