Rfid簡報

  1. 1. RFID Mifare Bill Chung
  2. 2. RFID簡介Radio Frequency Identification (無線射頻識別系統)頻率 LF:125K/135K Hz (範圍 10K~1MHz) HF:13.56MHz (範圍1M~400MHz) UHF:860~960MHz (範圍400M~1GHz) Microwave:2.4/5.8GHz
  3. 3. RFID 頻道 RFID: Toll Roads RFID: & Item RFID: Access Control RFID: Management Item Animal ID Smart Cards Management Microwave EAS Data TerminalLow Freq. EAS Mid. Freq. Cell Phone EAS TV Data Radio GarageModem Toys AM CB FM Door 10 kHz 100 kHz 1 MHz 10 MHz 100 MHz 1000 MHz 2.45 GHz 300 GHz 資料來源 EAS(Electronic article surveillance)
  4. 4. 常見相關ISO標準 LF HF UHF MicrowaveISO 11784 14443 15693 18000 11785 15693 18000 14223 18000 18000
  5. 5. RFID 的應用票券、電子錢包進出門禁管制、人員考勤、人員定位農業動植物識別製造業生產流程、倉儲流通業倉儲、POS圖書館管理
  6. 6. Mifare 概觀ISO 14443 AType Mifare UltraLight:64 Bytes without security Mifare Classic Mifare S50: 1K Bytes Mifare S70: 4K Bytes Mifare Prox (Mifare Desfire):4K Bytes Hardware Triple-DES Encrypt
  7. 7. Mifare S50 儲存格式 Sector Block記憶體:1KB 0 0 Manufacturer Code (UID) 16個Sectors 1 Data Block 4 Blocks / Sector 2 Data Block 16Bytes / Block 3 Sector Trailer (Key Data)Sector 0/Block 0: 1 0 Data Block 1 Data BlockManufacturer Code 2 Data BlockBlock 3: Sector Trailer 3 Sector Trailer (Key Data) . . . . . . . . . . . . . . . . . . . . . 15 0 Data Block 1 Data Block 2 Data Block 3 Sector Trailer (Key Data)

  9. 9. Access condition for Data Blocks
  10. 10. Access condition for the Sector Trailer
  11. 11. Tag與Reader如何通訊Tag Type Request Serial Anti CollisionNumber Loop Select Tag YES AuthenticationChange NoSector Read/ Write/ Increment Halt Decrement/ Transfer/ Restore
  12. 12. RFID專案的重點首要的考慮就是Tag 用途 加密與否及其重要性 環境因素 外觀與材質特性
