RFID transponders can be affixed on boxes and pallets as early as the production stage, communication between transponders and RFID readers is fully automatic, and they do the work by themselves.

• RFID radio frequency can usually penetrate an item's packaging and determine the contents
• Tags embedded in the package cannot be scraped or rubbed off or damaged
• Information on the tags can be written again to store further information
• There is information flexibility, whereby information on the tags can change as the goods move across the supply chain network
• Ability to read the data contained in the chip without line of sight
(Poirier & McCollum, 2006)
There is a conflict in the supply chain arena between proponents who believe that RFID tags will replace barcoding - a technology
of nearly 30 years - and opponents who believe that the investment does not provide a significant return on investment, given that
barcodes are still much cheaper than tags. The main argument against the use of RFID is the current near-universal use of
