Presentation Transcript

  1. RFID Technology Issues Interactive discussion. Intended to elicit comments and questions to lead towards White Paper outline.

  2. Discussion Topics • Security Discussion • Site Preparation Issues • Tag Selection & Placement

  3. RFID Security • RFID systems are similar to wireless networks in terms of security vulnerabilities • Attacks fall into two categories • Passive • Attacker “listens” • Active • Deliberate, malicious actions

  4. RFID Security -Passive • Same threat as barcode & human readable • Tag Contents are: • Pallet/Case/UID + CAGE + Serial Number • Add Part Number if using EPC Global format

  5. RFID Security -Active • Same threat as barcode & human readable • New Standards (Class 1, Gen 2) provides improved security: • Much longer passwords for: • Query Tag Data • Kill Tag • Lock Tag Data (Permanent or Temporary) • Better data encryption

  6. Site Preparation Issues • Risks: • Bi-directional Interference • Human exposure • Passive RFID operates in a range of 20 ft or less • Suggest site survey only when site inspection reveals need • Printer, Mobile, Stationary Options

  7. Tag Selection & Placement • Tag Selection • Different antenna configurations = performance differences • Start with “middle of the road” tag and change tag if needed • Test thoroughly in pilot study

  8. Tag Selection & Placement • Tag Placement • Mil-Std 129 dictates placement of carton markings • RFID is affected by fluids and metals • Corrugated cartons are easy • Test thoroughly

  9. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? • Questions • Concerns • Action Items
