    • RFID
      Everybodytalksabout RFID, buthow mature isthistechnology?
    • Scenario
      7824661
      RFID, as all technological solutions, has got its own life cycle
    • Scenario
      Life cycle of a technology
      Initial enthusiasm
      “That’s the perfect solution for…”
      “Anything is possible!”
      Adoption
      “Nothing is working!”
      Disillusionment
    • Scenario
      At which RFID technology life stage
      are we today ?
    • Scenario
      Today we are here!
      Initial enthusiasm
      RFID TODAY
      Adoption
      Disillusionment
    • The Good RFID Integrator
      At this stage, a good RFID integrator should
      • guide customer, evenbyimposingitself
      • project a realistic RFID system
      • not promise the impossible;-)
      • always bebasedon proven experience
      • remember RFID cannotguarantee 100%!!!
      This is so, more than in other technological fields
    • An RFID System
      A step backwards…
    • An RFID System
      What must an RFID System do?
    • An RFID System
      RFID = Radio FrequencyIDentification
      Object Identification Technology by Radio Waves
      RFID
      System
      Identification of
      due objects
      in a given context
      in front of a certain event
      An RFID tag is attached to
      every object, thus becoming
      univocally identifiable in the system
    • RFID Detection System
      RFID Detection System
      The goodstobeidentified
      go throughreading area, usually under a gate, and are detectedbythe system
      via reading of tagsattached on objectswhich, under the fieldcreatedby the gateantennas, report theiridentity,
      i.e. their “tagid”
      Gate
      Detection Area
    • An RFID System
      Tag (or transponder)
      It is the element attached to items-to-be-identified, containing tag id
      Antenna
      Itis the HW part transmitting/receiving
      radio waves for RFID tag info reading
      RFID
      System
      Reader
      Connectedtoone or more antennas, it converts electricsignalsintodigitalones, interpreting some of the info read on the tag
      Sensors
      Detect people/objects passing through, in order
      to identify items inside detection area
      Middleware
      Manages the whole system, processes data
      and makes them available to users
    • The Tag
      The tag is an object composed by
      • antenna
      • chip
      • support
      antenna
      I.C. (memory, logic & TX/RX circuits)
      plastic support
    • Factors influencing RFID
      Which factors affect functioning
      in an RFID system?
      n x m x p = “RFID works”
    • Factors influencing RFID
      1
      Material on which tag is attached
    • Material on which tag is attached
      Wood => OK
    • Material on which tag is attached
      Metal = !
    • Material on which tag is attached
      Liquids = !
    • Material on which tag is attached
      Oily Substances = OK
    • Factors influencing RFID

      Tag Density & Positioning
    • Tag density
    • Tag density
      VisibleTag
      InvisibleTags
      (no detection
      due to interference)
    • Tag positioning
    • Tag positioning
      VisibleTags
      Invisibile Tag
      (due toorthogonalfield lines)
