1 Radio Frequency Identification (RFID) Features and Functionality of RFID Including application specific ISO specifications Presented by: Chris Lavin Sarah Clark Spencer Prows

2 What is RFID? RFID is a technology, whose origins are found in the WWII era, that incorporates electromagnetic or electrostatic coupling in the RF portion of the EM spectrum to uniquely identify an object, animal or person. It is also gaining increasing use in industry as an alternative to the bar code. RFID is a technology, whose origins are found in the WWII era, that incorporates electromagnetic or electrostatic coupling in the RF portion of the EM spectrum to uniquely identify an object, animal or person. It is also gaining increasing use in industry as an alternative to the bar code. Requires a transceiver, antenna, and transponder Requires a transceiver, antenna, and transponder Can operate in Passive or Active Modes Can operate in Passive or Active Modes Source: http://searchmobilecomputing.techtarget.com/gDefinition/0,294236,sid40_gci805987,00.html

3 What is RFID? RF signals transmitted by the transceiver activates the transponder, which transmits data back to the transceiver. RF signals transmitted by the transceiver activates the transponder, which transmits data back to the transceiver. Transponder is powered by EM waves emitted by the transceiver Transponder is powered by EM waves emitted by the transceiver Various frequencies are used depending on the application Various frequencies are used depending on the application Requires no line-of-sight (like bar-codes) Requires no line-of-sight (like bar-codes) Source: http://searchmobilecomputing.techtarget.com/gDefinition/0,294236,sid40_gci805987,00.html

5 RFID Applications For toll booths (or any “pay for entry” system) For toll booths (or any “pay for entry” system) Airport Baggage ID Airport Baggage ID Car keys, wireless entry and ignition Car keys, wireless entry and ignition Animals Animals Hospital Patients Hospital Patients Instant history tracking Instant history tracking

6 RFID Shortfalls Cost Cost Transceiver ~ $1000 Transceiver ~ $1000 RFID Tags $0.20 each RFID Tags $0.20 each Not competitive with cost of barcode Not competitive with cost of barcode UHF signals problematic near metal and water UHF signals problematic near metal and water Reader Collisions Reader Collisions Can be overcome using TDMA Can be overcome using TDMA Tag Collisions Tag Collisions Required some engineering of tag transmit timing Required some engineering of tag transmit timing Security Concerns Security Concerns

7 RFID Standards and Specifications Application specific ISO standards
