R____ f________ i_____________(RFID) is the w_______ non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically i__________ and t_______ tags attached to objects. The tags contain electronically stored information. Some tags are powered by and read at s____ ranges (a few meters) via magnetic fields (electromagnetic induction). Others use a local power source such as a b______, or else have no battery but collect energy from the interrogating EM field, and then act as a passive transponder to emit microwaves or UHF radio waves (i.e., electromagnetic radiation at high frequencies). Battery powered tags may operate at hundreds of meters. Unlike a barcode, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object.

R____ f________ i______________ (RFID) is part of the family of A________ i_____________ and D___ C_____(AIDC) technologies that includes 1D and 2D bar codes. RFID uses an e_________ c___, usually applied to a substrate to form a label, that is affixed to a product, case, pallet or other package.
