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
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
Fulham Football Club • 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
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=eob532iEpqk&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
