3. RFID 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
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 is transmitted by the antenna circuit embedded in the
RFID inlay via radio frequencies, to an RFID reader 3 types Passive
Semi-passive Active
6. Types of RFID Tags 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 the chips
generated by the several meters circuitry, resist reader
interference and without having an circumvent a lack active
transmitter of power from the to transfer the reader signal due
information stored to long distance. They are different from active
tags in that they only transmit data at the time a response is
received
