3. RFID RFID = Radio Frequency Identification Electronic
labeling and wireless identificationof 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 fieldgenerated by a compatible reader, theytransmit this
information back to thereader, thereby identifying the object
4. RFID components A basic RFID system consists of
thesecomponents: A programmable RFID tag/inlay for storing
itemdata; Consisting of an RFID chip for data storage an antenna to
facilitate communication withthe RFID chip A reader/antenna system
to interrogate theRFID inlay Application software and a host
computersystem
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 RFIDchip is transmitted by the antenna circuitembedded in the
RFID inlay via radiofrequencies, to an RFID reader 3 types Passive
