This presentation provides an overview of RFID (radio frequency identification) technology. It defines RFID as using radio frequency tags to identify objects via radio waves. The presentation describes the basic components of an RFID system including tags, readers, and antennas. It discusses the history of RFID and barcodes and provides examples of current RFID applications in areas like inventory tracking, building access, toll collection, and smart appliances. Both advantages like automatic identification and disadvantages like privacy concerns are outlined. Regulations surrounding RFID are also briefly addressed before concluding with predictions about the continued growth and standardization of RFID technology.

3. What is RFID?
 RFID is an acronym for radio frequency
identification.
 Briefly the RF stand for “radio-frequency” and ID
means “identifier” that allows an item,
 The use of radio frequency tags to identify real
objects, for instance a library book, to be identified,
accessed, stored, reprogrammed and communicated
by using radio waves

4. Brief History
 First Bar code patents – 1930s
 First use of RFID device – 2nd world war – Britain used
RFID-like technology for Identify- Friend or Foe
 Commercial Operation begun from 1960’s …
 In 1970s developers, inventors, companies, academic
institution and government sectors were actively worked
on RFID
 Most common application were tracked person and
objects, identified goods in supply chain, reusable
container, high value tools, security, controlling access to
building, networks, payment systems and other assets.

9. Passive Tags Active Tags
 No battery: passive
tags use the incoming
signal through
induction
 Passive tags only
function in the closer
range (at the most a
few meters).
 Low cost: Generally,
$0.15 to $5.00
 Active tags are powered
by batteries.
 Longer range (100m+)
 High cost: Generally,
$15 to $100

10. RFID Applications
 Tracking Books in Libraries
 Inventory Tracking:
Walmart required it of their
top 100 vendors
 Authorized building access
(Prox Cards)
 Passports (US passports
recently)
 AmEx Blue credit card
 Prison inmates (embedded)
 Livestock Tagging
 Passive / Secure Entry
 Airline Baggage Tracking
 Postal Package Tracking
 Time and Attendance
 Electronic Article
Surveillance (EAS)
 Automated Toll Collection
 Vehicle Anti-Theft
 Wild Animal Tracking

 Recognizes what’s been put in it
 Recognizes when things are removed
 Creates automatic shopping lists
 Notifies you when things are past their expiration

14. RFID’s Advantages
 Automatically identify
objects
 Store data on a tag
 Can be hidden
 Work in harsh
environments
 Improve Customer
Services
 Easily Prevent Theft
 An AUTO-ID based
System
 A method for controlling
inventory
 Saving Time and Money
 Minimize Work Stress of
Staff
 Offering Self Check out/in

15. RFID’s Disadvantages
 Lack of standards!
 Short range in case of passive tag
 Cost
 Privacy concerns

16. Privacy Concerns
 Tracking an individual’s movements. If RFID tags are embedded in
clothing or vehicles, for example, and if there is a sufficiently dense
network of readers in place, it becomes possible to track those tags in
time and space.
 Sense of limiting or controlling: the revelation of personal information
such as medical prescription or personal health histories could have an
impact on the availability of insurance or employment;
 Information leakage. Consumer rights organizations worry about the
possibility that e.g. authorities or thieves will be able to monitor people’s
personal belongings through small embedded RFID microchips
remaining active after purchase.
 Impersonation: Impersonation of RFID tags can be achieved by tag
cloning, tag swapping, tag reprogramming or spoofing.

possibility

18. Regulation
 Currently no global body governing RFID frequency
allocation
 In Europe, tags must be removed from packaging
before disposal due to recycling disruptions and
health regulations
 There is limited or no regulation of RFID’s for the
most part leading to more controversy

19. Conclusion
 RFID technology is rapidly is becoming more
standardized, but problems do still exist
 The number of adopters of RFID technology is
growing
 Regulation and education is necessary to quell some
of the fears regarding RFID technology and it’s
implications
