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