ABSTRACT:
Radio-frequency identification (RFID) apparatus and methodology enable a plurality of or all of the RFID tags in a stack of items such as cartons and boxes—including items that do not have a line of sight to a reader—to be read. An RFID system includes RFID tags and a transmission line. The RFID tags are mountable to items to be read and include an RFID circuit that generates tag energy when activated by activation energy from a reader. The transmission line carries activation energy from the reader and tag energy from the tags. The transmission line is positionable in operative or coupling proximately to a plurality of the tags when the plurality of the tags are mounted to items and when the items are stacked. Accordingly, when carrying activation energy from the reader, the transmission line couples with and thereby enables activation of the plurality of the tags. Further, when the plurality of the tags are activated and generating tag energy, the transmission line couples with and carries the tag energy from the plurality of the tags. The transmission line can be configured as an elongated adhesive tape-like structure that can be adhered across a plurality of RFID tags mounted to a plurality of items. The transmission line can also be disposed on an inter-item reading device that can be positioned between adjacent rows of stacked items.
