RADIO FREQUENCY  IDENTIFICATION(RFID) IDENTIFICATION(RFID) TECHNOLOGY 

 ABSTRACT

Radio-frequency Radio-frequency identication (RFID) is a technology that uses communication communication via electromagnetic electromagnetic waves to exchange data between a terminal and an electronic tag attached to an obect! for the "ur"ose of identication and trac#ing$ %ome tags can be read from several meters away and beyond the line of sight of the reader$ Radio-frequency identication involves interrogators (also #nown as readers)! and tags (also #nown as labels)$ &ost RFID tags contain at least two "arts$ 'ne is an integrated circuit for storing and "rocessing information! modulating and demodulating a radiofrequency (RF) signal! and other s"ecialied functions$ he other is an antenna for receiving and transmitting the signal$  *assive tags collect energy from a nearby RFID reader+s interrogating radio waves$ ,ctive tags have a local "ower source such as a battery and may o"erate at hundreds of meters from the RFID reader$ nli#e a barcode! the tag need not be within the line

of sight of the reader! so it may be embedded in the trac#ed obect$ RFID is one method for ,utomatic Identication and Data .a"ture (,ID.)$
