6. • It is a Technology
depending on Radio
Frequency Waves.
• This radio waves used to
read and capture
information stored on a
tag attached to an object.
What is RFID

7. Objects Could be…
• Books in Library

8. Objects Could be...
• Items in a Shopping
mall

9. Objects Could be...
• Items in Inventory

11. How does a RFID system work?
• RFID System is made up of two parts
a tag or label and a reader.
Tag’s components Microchip
Antenna
Reader’s components
Transceiver
Microprocessor

14. Types of RFID tags
Passive Battery powered
Relay its stored information back to the interrogator
using
Reader’s radio wave energy.
Embedded with a small battery that powers
the relay of information.

16. Working Principle
• RFID tag and Reader communicate by Coupling Mechanism.
• The most important principles – “inductive coupling” and “backscatter coupling”.
• Inductive Coupling • Backscatter Coupling

17. 1.Inductive Coupling
• Magnetic field created by reader’s
antenna.
• Coupling takes place.
• AC voltage rectified & filtered to DC.
• Load switched with particular frequency.
• Reader detects data.
Low & High freq. systems based on this type with carrier freq.
<135KHz (Low) and at 13.56MHz (High).

18. 2.Backscattering Coupling
• Depends on Electromagnetic waves created by
the reader.
• Tag’s antenna capture reader’s sine wave signal
(AC).
• AC voltage rectified & filtered to DC.
• Data stored sent back by switching load on and
off
or changing the properties of the tags
themselves.

20. Applications of RFID.
• In chaotic manufacturing, shipping, and
distribution environments, real-time
data on the status of individual items
provides insights that turn into
actionable measures.
1. Logistics & Supply Chain Visibility

21. 2. Race timing
• Timing marathons and races are one of the most popular uses of RFID,
but often race participants never realize they’re being timed using RFID
technology.

22. 3. Attendee Tracking
a) Track Traffic Flow
 Real-time information gives you
ability to be agile.
b) Measure Attendance at Sessions
 Learn which speakers are popular.
 Understand what your attendees are
interested in.

23. 4. Access Control
• Certain areas require an expected level of security and access.
5. Laundry Management
• operations can track which uniforms were assigned to
specific employees, the age of uniforms, the number of times
washed, and identify missing uniforms.

24. 6. RTLS (Real Time Location System)
• RFID used to track the real-time location of assets, employees, or
customers. Whether you’re measuring the efficiency of worker
movements, or tracking the location of valuable resources, RFID
systems provide visibility in any number of locations.
