Radio frequency identification is a contactless technique that uses the radio waves to identify the object uniquely. RFID tag and reader are major two parts of the RFID system. Tags are used to store the information about the object and Readers read tag's stored information when tag enters in the range of the reader. This paper provides the information regarding the current scenario of the RFID technology. Aside from the introduction of the working of RFID, discussion is made on major types of the RFID tags and Readers, comparison with bar code as well as current application areas have been presented.
