Mr. Majid presented on Radio Frequency Identification (RFID) technology. RFID uses radio waves to identify and track people and objects. An RFID system has two main components: RFID tags, which contain chips and antennas, and RFID readers, which are transceivers. When an RFID tag comes within range of a reader's radio signals, the tag is activated and sends its stored information to the reader. The reader then decodes the data and sends it to a connected network or database. RFID has various applications including animal identification, anti-theft systems, luggage handling, blood banks, and office printers/cartridges.

2. Topics Covered
• Definition of RFID
• RFID History
• Components of a RFID System:
• How does a RFID system work?
• Use of RFID

3. Definition of RFID
• Technology used to track and identify a
person or object by means of radio waves.
• Identification system consists of chip-
based tags and readers.

4. RFID History
• “Identify Friend or Foe” (IFF) systems developed
by the British to identify friendly aircraft.
• IFF still used today for aircraft
Don’t shoot! We’re British!
Oh. We’re British too!

5. Components of a RFID System
Two main components to a basic RFID
system:
RFID Tag (transponder) Chip (IC)
Antenna
RFID Reader (transceiver)

6. How does a RFID system work
Object to be tracked is fixed with RFID Tag.
The Reader is kept at some distance.
Object containing RFID tag comes within the range
of radio signals emitted by reader, the Tag is
activated and starts sending information stored in it.
The Reader captures the radio signal, and decodes
it to a byte stream and sends information for further
processing to the system connected to it.
