Radio Frequency Identification
2
what is an RFID?

• A contactless technology enabling a new and
  exciting world of experiences for connected
  consumers and streamlined business operations
• Enables automatic collection of product, place,
  time or transaction data quickly and reliably
• Characteristics - reliable and proven
  technology- immune to dirt and harsh
  environments - allows reading of multiple tags
  - no line of sight required

limitations frequency differences
US, Canada 125KHz 13.56MHz 902-928MHz
EU Countries 125KHz 13.56MHz 868-870MHz
Japan 125KHz 13.56MHz 950-956MHz
14
limitations signals and materials
15
issues

• too expensive
• no standards
• privacy and security issues
• huge amount of trash data
• social and political issues

16
what to choose... - technical issues

• transmitter and receiver frequency/range
• different standards/techniques
• gov't limited
• signal corruption and absorption
• approach to a solution
• more expensive but better technique
• international standards
• limitations and restrictions in usage

17
what to choose... - security and privacy

• being tagged and monitored
• customer aversion
• a false sense of security
• information available literally to anyone
  interested
• local privacy violation?
• network of rfid equipments
• approach to a solution
• kill switch in rfid equipped items
