RFID RFID = Radio Frequency Identification Electronic labeling and wireless identification of objectsusing 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 acompatible reader, they transmit this information back tothe reader, thereby identifying the object 4. 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 system 5. 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 istransmitted by the antenna circuit embedded in the RFIDinlay via radio frequencies, to an RFID reader 3 types Passive Semi-passive Active 6. 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 fielddistances of several chips circuitry, resist generated by themeters interference and reader circumvent a lack of without having an power from the readeractive 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 received 7.
