3. RFID
• RFID = Radio Frequency Identification
• Electronic labeling and wireless identification of
objects using radio frequency
• Tag carries with its information
o a serial number
o Model number
o 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:
o 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
o A reader/antenna system to interrogate the RFID inlay
o 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
o Passive
o Semi-passive
o Active

6. Type 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 several the chip’s generated by the
meters circuitry, resist reader
interference and • without having an
circumvent a lack active transmitter
of power from the to 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
