  4. How does it work? application server reader tag database Image Courtesy : ISSE

  5. Other points: • Chip size: about a rice grain to about a dime • Costs: 50c to $50 • depends on size, volume, and sophistication

  6. Types of RFID • Based on mobility: • Fixed • Toll tags • Mobile • Handheld readers = reader

  7. Types of RFID (2) • Based on performance: • Active • Battery powered • Long-distance reader • 3-8 years life • Passive • Non battery powered • Short-distance reader • Up to 10 years life

  8. RFID all around you! • RFID credit cards • Employee badges • Toll passes • Passports • Movie tickets

  9. For the common good • patient identification • animal tracking • Electronic Product Code (EPC) • robbery detection

  10. Privacy and Security Risks • Privacy Risks • Rogue scanning • Eavesdropping • Security Risks • Identity theft • Tracking

  11. How realistic is the threat?

  12. Technical Solutions • ‘Kill’ and ‘sleep’ tags • Brute-force methods • Break or tear object • Place cover around object

  13. Other Solutions ? • Educate: not all RFID bad • Demand/support legislation on RFID • Legislate applications, not technology
