  1. RFIDs and the Future Logistic System

    Dr. Hayden So Department of Electrical and Electronic Engineering 17 Sep, 2008
  2. What we have today… UPC (Universal Product Code) JAN (Japanese Article Number) EAN (European Article Number)
  3. Article Identification – Bar Code UPC, EAN, JAN: Uniquely identify a type of product with a set of digits + check-digits UPC: 12 digits EAN, JAN: 13 digits Identify products at point-of-sale Online shopping Country code Company code Product code
  4. Limitations of Bar Codes Only useful with line-of-sight Limited information Error Prone Dirt on label, wear, etc Alternatives: RFID: Radio Frequency ID Electronic Product Code (EPC) Passport Access Control E-money
  5. RFID Radio Frequency IDentification A method to retrieve/store information remotely using RFID tags Three parts in the system: An RFID tag An RFID reader IT Applications 3 Categories Passive Active Semi-Active
  6. Inside Passive RFID tags Many shapes of antenna NO power source Come from antenna CHEAP!
  7. RFID at work – Octopus Card Introduced in Hong Kong in September 1997 Today 50,000 readers > 17 million cards (HK’s population is 7 million) > 10 million transactions per day HK$85 million per day Sony FeliCa technology World Information Technology and Services Alliance's 2006 Global IT Excellence Award: Chairman's Award
  8. RFID at Work – Credit Card All three major credit card companies have RFID embedded cards VISA: payWave MasterCard: PayPass American Express: ExpressPay All cards use the same international standard ISO 14443
  9. RFID at Work – Hong Kong International Airport 110,000 bags per day = 1.27 bags per second
  10. RFID at HKIA Hong Kong RFID Awards Most Innovative Use of EPC/RFID: Gold Medal
  11. Other Places You Can Find RFIDs? Olympics Ticket Automatic Toll Collection System and more… Passport Access Card
  12. Future Shopping – RFID Mirror Clothes tagged with RFID tags Smart mirror display corresponding information automatically Touch surface allows user interaction
  13. Security and Privacy People concern with security and privacy because information is transmitted over-the-air Easy for sniffer to steal information without stealing your card Many levels of encryption and security measures in place But… still need to be low cost Many system hacked already E-Passport cloned Encryption for popular access card using Mifaretechnology cracked
  14. Summary RFID is going to be everywhere Still need better engineering Need very smart antenna and low-power electronics design Need very large IT systems to manage all the information scanned Need to make it secure Need to be CHEAP Hong Kong has the most advance RFID systems in the world
