RFID (radio frequency identification) technology is used to identify and track objects using radio waves and can store unique data about each object. It has various applications, including in libraries, shopping malls, and businesses where employees may have RFID microchips implanted for convenience. While RFID offers advantages such as greater data storage and ease of use compared to barcodes, it also raises concerns regarding cost, privacy, and programming time.

3. What is RFID?
RFID(Radio Frequency Identification) technology works on radio waves
that is used to identify and track objects.
Small electronic device capable of storing 2 kilobytes(or less) data that
provides unique identity to an object.

4. It could be used to identify books in a
library.

5. Or.. It could be used to identify items in
shopping malls.

6. or.. It could store your personal information and act as an
ID card.
It is also used for identifying and track animals.

7. History
RFID was invented in Harry Stockman in 1948.
Commercial use started in 1990.
It was firstly used during WW2 by United Kingdom to identify enemy
planes.

8. RFID System

9. RFID System
RFID Reader RFID Tag
Active Tags
Passive Tags
Semi-passive Tags

10. RFID Reader
RFID reader is a two way radio transmitter-receiver used to gather
information from a RFID tag.
RFID reader sends a signal to a tag and also receives/reads its response.

11. It could be a handheld scanner.

12. Or.. It could be a door
lock.

13. Or.. It could be a card reader (in office for entrance).

14. RFID in business
Nowadays, companies have agreed to implant RFID microchips inside
their employees body for security and for ease of use.
They implant RFID chips in staff members' hands in between their
thumb and forefinger.

18. WHY ???
Once implanted, a staff members can perform couple of things just by
the wave of their hands like opening doors, use of copy machines,
logging into our office computers, unlocking phones, sharing business
cards, storing medical/health information, and used as payment at other
RFID terminals.

19. Advantages
1. Unlike barcode reader should not be in LOS for sending and receiving
signals.
2. RFID tags can store more information.
3. Effective way to track animals as well as other objects.
4. Unlike barcode these tags can read as well as write.

20. Disadvantages
1. Active RFID tags are costly due to batteries.
2. Privacy is a concern because they can easily be tapped.
3. RFID devices take large amount of time during programming
4. Lack of awareness in people.
