Abstract
A portable, multi-mode RFID reader is capable of operating in a plurality of interrogation modes. The reader includes a processor configured to select either a subset of the plurality of interrogation modes according to which the RFID reader will operate when interrogating a set of one or more RFID tags, a sequence in which at least some of the plurality of interrogation modes are employed when the RFID reader interrogates the set of RFID tags, or both. Configuration of the processor as described is such that the RFID reader may consume less power, interrogates the set of one or more RFID tags more quickly, or both consume less power and interrogate the set of one or more RFID tags more quickly.
