ABSTRACT:
Systems and methods for efficiently querying and identifying multiple items on a communication channel are disclosed. The inventions preferably uses radio frequency identification with interrogation devices and systems that identify radio frequency identification transponders. A depth-first tree traversal protocol algorithm, including commands and symbols, is used to more efficiently interrogate a plurality of transponders in a short amount of time.
