RFID RFID = Radio Frequency Identification Electronic labeling and wireless identification of objects using radio frequency Tag carries with its information • a serial number • Model number • Color or any other imaginable data When these tags pass through a field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the object10/23/2012
RFID COMPONENTS A basic RFID system consists of these components: • A programmable RFID tag/inlay for storing item data; • Consisting of an RFID chip for data storage • an antenna to facilitate communication with the RFID chip A reader/antenna system to interrogate the RFID inlay Application software and a host computer system10/23/2012
RFID TAG The RFID tag consists of an integrated circuit (IC) embedded in a thin film medium. Information stored in the memory of the RFID chip is transmitted by the antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader 3 types • Passive • Semi-passive • Active10/23/2012
TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags • Use a battery • Contain built-in • Derive their power • communicate over batteries to power the from the field distances of several chip’s circuitry, resist generated by the meters interference and reader circumvent a lack of • without having an power from the reader active transmitter to signal due to long transfer the distance. information stored • They are different from active tags in that they only transmit data at the time a response is received10/23/2012
