Abstract
A method for creating a hierarchy of radio frequency identification (RFID) tags and the resultant system include associating each of a plurality of first RFID tags with an individual object of a plurality of objects, each first RFID tag storing identification information about the object with which it is associated. Identification information about each of the first RFID tags is stored in a second RFID tag that can physically accompany the first RFID tags during transportation.
