Abstract
Methods for efficiently querying and identifying multiple items on a communication channel are disclosed. The methods preferably use 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, preferably is used to more efficiently interrogate a plurality of transponders in a short amount of time. The communication channel may be an RFID communication channel or a wired communication channel. The time required to obtain the identification numbers of the objects may be made deterministic. The objects to be identified may be clothing, luggage, furniture, computers, parcels, vehicles, warehouse inventory, components on an assembly line or documents.
