"Radio Frequency Identification - RFID"
" MAIN OBJECTIVE OF THIS ARTICLE" ü Know what is RFID? ü Know the components of an RFID System ü Applications of RFID and implementation of RFID in respective fields “Radio Frequency Identification” - (RFID) can be seen as a micro-chip in a label used to transmit data when it is exposed to radio waves. RFID use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. Radio-frequency identification ( RFID ) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically-stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source (such as a battery) and may operate hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the
