  • Automated Identification (AutoID)
    • Barcodes
    • RFID
  • Does this have anything to do with the Web?
    • Not really, but this is an intro class and you use this technology every day whether you’re aware of it or not
autoid
AutoID
  • How we tag ourselves and our stuff so that computers can read them
  • Users:
    • Automated Supply Chain Management (transportation, warehousing, distribution of goods, and EDI to track it all)
    • DoD: Inventory control
    • Document tracking (Law offices, gov’t)
    • Car registration stickers, etc
barcodes as autoid
Barcodes as AutoID
  • Alternating bands of black and white to be read by specific readers to convert into numbers / letters
  • First uses: grocery stores (checkout lines)
  • Inventory control
  • Document management
  • Allows presence of item to be quickly recorded by computer, the reading of which subject to interpretation by usage
    • Checkout line: you’re buying what was scanned
    • Washington Park: you shouldn’t have parked there

RFID
  • Radio Frequency ID tags
  • Like barcodes, but using short range radio
  • No direct line of sight required. Can scan tagged items in your pocket / pocketbook (like newer passports)
  • Radio waves activate tiny transmitter that sends ID code to receiver
  • Can scan without your knowledge / consent

  • Tags can cost 10 – 30 cents: soon to cost 5 cents
  • Expensive products can be tagged – computer printers, cosmetics, or other small, expensive goods
  • Great for inventory control
  • What happens when you throw goods away?
  • Dumpster divers know you bought something expensive without going for a plunge! (more a problem in urban areas)
