3. RFID = Radio Frequency Identification Electronic labeling
and wireless identificationsof 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
generatedby a compatible reader, they transmit thisinformation back
to the reader, therebyidentifying the object
4. 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
with the RFIDchip A reader/antenna system to interrogate theRFID
inlay Application software and a host computersystem
5. The RFID tag consists of an integrated circuit(IC) embedded
in a thin film medium. Information stored in the memory of theRFID
chip is transmitted by the antennacircuit embedded in the RFID
inlay via radiofrequencies, to an RFID reader 3 types Passive
