- 3. 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 a compatible reader, they transmit
this information back to the 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

Use a battery Contain built-in Derive their power communicate over
batteries to powerfrom the fielddistances of the chips circuitry,
generated by theseveral meters resist interference reader and
circumvent a without having an lack of power fromactive transmitter
the reader signal to transfer the due to long information stored
distance. They are different from active tags in that they only
transmit data at the time a response is received
