Abstract
The present invention relates to the field of radio frequency identification (RFID). In one form, the invention relates to a method and/or device adapted to provide at least some level of providing lateral discrimination within a given area. The invention has been developed primarily for interrogating multiple passive transponders which are attached to objects to be identified by those respective transponders and will be described hereinafter with reference to that application. A typical application is the identification of RFID transponders or other RFID devices, such as those embedded in plastic tokens or cards within a selected area and which may be provided near each other or stacked on each other.
