The Wave of the Future

2.  History of RFID
 Types & Systems
 Current Uses
 Future Applications
 Controversies

3.  A technology that employs a microchip with an
antenna that broadcasts its unique identifier
and location to receivers.
 Employs a microchip called a smart tag,
broadcasts unique 96-bit identifier to receiver.
 Receiver relays the data to a computer.

4.  Does not require human to manually pass item
over scanner.
 More accurate inventory count.
 Can be incorporated into product, person,
animal.
 Can track each individual item.

5.  1939
 IFF Transponder
 Used by allies in WWII
 1945
 Leon Theremin
 Espionage tool for Soviet Union

6.  1973
 Claims U.S. patent was first true ancestor
 1980
 Retail
 Use of RFID in tracking and access applications
appeared
 Price, color, date of purchase

7.  Contains two main parts:
 Silicon chips
 Antennas
 Components enable tags to receive and
respond to radio frequencies queries from
RFID transceivers.
 Three types:
 Passive
 Semi-Passive
 Active

8.  Passive
 Have no internal power supply
 Electrical current inducted in antenna by the incoming signal
proves power for integrated circuit in tag to power up and
transmit response
 Very Small, Limited Range, Unlimited Life
 Semi Passive
 Similar to passive tags, with the addition of a small battery
 Battery powers the integrated circuit
 Bigger, Longer Range, Limited Life
 Active
 Have their own internal power source
 Many operate at fixed intervals
 Also called beacons (broadcast own signal)
 Large ( coin), Much larger memories, Longer range

9.  Objects equipped with
RFID tag
 Tag contains
transponder with
digital memory chip.
 Interrogator: an antenna
packaged with transceiver
and decoder.
 emits signal activating
tag.
 Reader detects activation
signal, decodes the data
on the tag’s silicon chip.
 Data passed to host
computer.

10.  “Line of Sight” Technology
 RFID superior over Barcode
 Elements and accidents can disturb or damage
barcodes
 Best Buy, Wal-Mart, And Target began
implementation
 Efficient in ability to track & respond accordingly

11.  Wal-Mart now requires its suppliers to use
RFID tags on shipping crates and pallets to
improve inventory management in the supply
chain.
 Fed Ex bought RFID-enabled aircraft from
Airbus to reduce maintenance time and costs.
 Cattle and farm animals are being tagged to
improve tracking and monitoring of health.

12.  U.S. Department of Defense – to better track
goods along supply chain (logistics and
inventory).
 Electronic payment – credit card companies
moving to RFID-enabled cards to increase
efficiency and reduce time at point-of-sale for
customer, merchant, and card issuer.

13.  Medical
 Drug
Counterfeiting
 Tracking & Tracing
 Medical
“Passports”
 Foster Care System
 Food Chain
Precautions
 Shopping
 Cashier-less check
out and payment
 Household Technology
 Smart keys
 Intelligent washing
machines
 Monitoring
refrigerators
 Intelligent
ovens/microwaves

14.  Privacy
 Consumer Rights
 Consumers should be informed if their products have
an RFID tag.
 Tracking of consumers (Profiling)
 RFID chips withstand dirt and scratches and can be
scanned from distances upward of 25 feet.
 Personal Information Leakage.
 Drawing the Line – Need for Legislation?
 Who Should Regulate?

15.  “Killing” of RFID Tags
 Tracking vs. the washing machine
 Options of killing after purchase
 Medical
 Implants/Personal Information
 Verichip is a tiny implantable chip that holds medical
records
 Bracelets to track infants in medical wards and elderly
in nursing homes.
 Used in animals for tracking.

16.  Medical
 Health Risks
 Hard to remove once implanted.
 Long term effects unknown.
 Religious
 Mark of the Beast, etc.
 The implanted RFID chip is certain to inflame Christian
fundamentalists, some of whom believe that such chips are
the Satanic “mark of the Beast” predicted in Revelations
13:16 “And he causeth all, both small and great, rich and
poor, free and bond to receive a mark in their right hand, or
in their foreheads.”

17.  Slowly becoming an industry standard
 Speeds up the supply chain process
 Easier to manage inventory
 Continually evolving
 Controversial technology

18.  Define RFID technology?
 When was RFID introduced?
 What are two main reasons RFID is
controversial?
 Name the three types of RFID tags?
 How are they currently using RFID tags?
 How is RFID Technology expected to effect
households?
