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 several the chip’s circuitry, generated by the
meters resist interference reader
and circumvent a • without having an
lack of power from active transmitter to
the reader signal transfer the
due to long information stored
distance.
• They are different
from active tags in
that they only
transmit data at the
time a response is
received
