3. RFID = Radio Frequency Identification Electronic labeling
and wireless identification of 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
generated by a compatible reader, they transmit this information
back to the reader, thereby identifying the objectRFID
4. 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 systemRFID
components
5. The RFID tag consists of an integrated circuit (IC) embedded
in a thin film medium. Information stored in the memory of the RFID
chip is transmitted by the antenna circuit embedded in the RFID
inlay via radio frequencies, to an RFID reader 3 types Passive
Semi-passive ActiveRFID Tag
6. Active Tags Semi-passive Tags Passive Tags Use a battery
Contain built-in Derive their power communicate over batteries to
power from the field distances of several the chips generated by
the meters circuitry, resist reader 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 Types of RFID Tags
