3. 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 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 RFID chip 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 the
RFIDchip is transmitted by the antenna circuitembedded in the RFID
inlay via radiofrequencies, to an RFID reader 3 types Passive
Semi-passive Active
6. Active Tags Semi-passive Tags Passive Tags Use a battery
Contain built-in Derive their power communicate over batteries to
power from the fielddistances of several the chips generated by
themeters circuitry, resistreader interference and without having
an circumvent a lack of active transmitter to power from the
transfer the reader signal due to information stored long distance.
They are different from active tags in that they only transmit data
at the time a response is received
