I write a degree work about tracking \ tracing systems for iron ore (systems like Siemens-Silag and different transponder systems). Please, what systems do you all use in your companies to track \ trace the product? Any information can be useful. I have to find out what advantages and disadvantages have all these systems (especially Siemens-Silag) and transponder systems.

thank you all in advance!
