RFID

possible graphs (vs time)

• usage
• news
  • topix: not normalized, only 1 year
• research papers
• rfid website traffic
  • use rank?
• cost
• size
• search queries
  • google trends: not long enough time period
• identifiers assigned (?)

intro

• passive ones get power from rf signal, transmit back (possibly with data)
• data may be in: Serial EEPROMs (SEEPROMs) come in a range of capacities from a few bytes to over 128 kilobytes http://en.wikipedia.org/wiki/EEPROM

specs

• As of 2006, the smallest such devices measured 0.15 mm × 0.15 mm, and are thinner than a sheet of paper (7.5 micrometers) http://en.wikipedia.org/wiki/Rfid http://www.eetimes.com/news/design/showArticle.jhtml?articleID=179100286
• The lowest cost EPC RFID tags, which are standard chosen by Wal-Mart, DOD, Target, Tesco in the UK and Metro AG in Germany, are available today at a price of 5 cents each http://en.wikipedia.org/wiki/Rfid http://www.rfidjournal.com/article/articleview/2295/1/128/
• Passive tags have practical read distances ranging from about 10 cm (4 in.) (ISO 14443) up to a few meters (EPC and ISO 18000-6) depending on the chosen radio frequency and antenna design/size http://en.wikipedia.org/wiki/Rfid

tech

• range:
• active ones better range, especially in fluids (eg in human/animal)
• wrapping in aluminum foil makes more difficult/impossible http://www.slais.ubc.ca/courses/libr500/04-05-wt2/www/T_Gnissios/problems.htm

uses of rfid

• remote sensors
• tracking - manufacture, distribution, inventory, anti-theft, sale, recall, etc
  • also for livestock, pets, people
  • identity (eg in people, passports, etc., inmates)
• payment (eg public transportation, electronic tolls), cards, etc.
• keyless cars

• rfid been around for decades - why now? - lower cost, size, also standardization

who using?

• Wal-Mart
• DoD
• Canadian Cattle Identification Agency
• lot of transportation stuff
• Malaysian, UK, now US passports

close to home

• 407 toll transponder (active)
• uw library (in-progress)
  • as of Sept 27 >800,000 items tagged (>50% done) http://www.lib.uwaterloo.ca/staff/isig/progress.html
  • Will the RFID system impose on our patrons' privacy? No. The tags only contain the barcode information of the book being checked out. Once the RFID tag is deactivated during check-out, there is no way of tracking the book. Circulation Services will follow the same procedures as before for maintaining borrowing information in our patrons records. http://www.lib.uwaterloo.ca/staff/isig/faq.html#health
