THESIS Radio Frequency Identification (RFID)
technology is widely used today and has many potential uses in the future.
CONTENTS Introduction Technology background History Today’s usage Potential usage
Pros Cons
RFID TAGS A technology that uses communication
via radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking.
RFID TAGS CONT. Radio-frequency identification involves a few
components: Interrogators (known as readers) Tags (known as labels)
Integrated circuit for storing/processing data Antenna for receiving/transmitting a signal
RFID software or middleware
RFID TAGS CONT. Three types:
Passive Using no battery
Active Using battery (always beaconing signal) Can be read from farther distances
Battery Assisted Passive (BAP) Small battery onboard activated in presence of reader
RFID TAGS CONT. Read Only
Memory is factory programmed, cannot be modified
Very limited quantity of data can be stored, usually 96 bits
Can be easily integrated with data collection systems
Typically cheaper than read-write tags Read-Write
Can be as well read as written to Data is dynamically altered Can store a larger amount of data, typically
ranging from 32 kBytes to 128 kBytes More expensive
HOW IT WORKS CONT. Passive Tags
RFID tag passes through presence of scanner and detects activation signal
Radio waves are sent from reader to tag Coiled antenna within the tag forms a magnetic
field Tag draws power and energizes circuits in the tag
and sends information encoded in memory
HOW IT WORKS Active Tags
Batteries power circuits to send radio waves to a reader from an antenna on the tag (like a cell phone to a base station)
Reader’s antenna receives information to be stored
HOW IT WORKS CONT. Battery Assisted Passive (BAP) Tag
Battery used to maintain memory in the tag or power the electronics that enable the tag to modulate the reflected signal
Acts same as passive when communicating
HOW IT WORKS CONT.
HISTORY Traced back to WWII Warn of approaching planes First patent for an RFID tag was in 1973
Active tag, rewritable memory Same year, passive transponder was used to
unlock a door without a key
CURRENT USAGE Inventory tracking
http://www.youtube.com/watch?v=4Zj7txoDxbE Race timing Pay tolls (EZ-Pass) Passports Pet doors Tracking devices Hospitals Refigerators Casino chips
MERCHANDISE RFID tags on clothes, CDs, movies, etc. Reader at door
Alarm sounds when not deactivated at register
RACE TIMING Timing is everything Active and Passive Boston Marathon
Checkpoints
EZ-PASS Electronic toll collection system Drive through tolls without stopping Automatically takes money out of account RFID mounted behind rear-view mirror Antenna mounted above road
PASSPORT Chip contains persons information
Name, nationality, gender, DOB, POB, digital photo
RFID matches paper More difficult for tampering
Encrypted digital signatures Can break the RFID chip with a hammer
Doesn’t invalidate the passport
PET DOOR RFID tag on pets Reader on door Allow pet to go in and out
Will not allow foreign pets in (neighbor’s pets can’t eat your pet’s food)
JAPAN TRACKS KIDS RFID tags on school children’s backpacks in
Osaka Readers mounted on the doors
Unauthorized visitors will be denied access Track movements of minors
Allows parents to know their kids got to school safely via mobile phone
Cards with RFID given to season ticket holders Contains info about paid games Can update card via phone or computer If stolen, unique code will deactivate card, and
new one may be purchased Cut lines at turnstiles
Went from 10-20 seconds to 4 seconds per ticket Increases safety
Nearby roads are now empty on game days due to decrease in lines
FULHAM FOOTBALL CLUB
HOSPITALS New York and Germany Tagging patients Bracelets are scanned by doctors
Patient records, correct dosage of drugs Tagging blood
Right blood reaches right person
SAMSUNG REFRIGERATOR Samsung RFID enables refrigerator Tells current contents of fridge Can tell what you are low on Displays recipes that you currently have
stocked Working on displaying info on laptop/phone Predicted that when TV’s are RFID, custom
commercials will be displayed by what is low in the fridge
LAS VEGAS CASINOS RFID imbedded in high value chips Readers around casino
Prevents counterfeiting, stealing Track betting patterns Decrease dealer errors
CURRENT SECURITY Encryption Tin foil method Passport case
IBM COMMERCIAL http://www.youtube.com/watch?v=eob532iEp
qk&playnext=1&list=PL1E873E327447330F Very controversial Privacy laws updated Security is a huge concern
+
POSSIBLE TECHNOLOGIES Own home Temperature/scents of each
room Music, TV Programs. Already in use Given to guests
as necklace
POSSIBLE TECHNOLOGIES CONT. Washing Machines,
automatic washing. Use in paper money it
eliminate counterfeit and track criminals
Cash just as traceable as credit card if linked to drivers license
POSSIBLE TECHNOLOGIES Use on produce,
track shopping trends. Stores write information to your drivers license or credit card RFID.
Easily track food force source, making food supply chain much safer
POSSIBLE TECHNOLOGIES CONT. Uses in roads to
prevent accidents.
Automatic driving?
Gun control, registration
RELATION TO IS Database usage Middleware is used Security measures Rapidly growing field
