Zebra-RFID-access-control1It’s time for part 2 of our closer look at RFID frequencies and technologies. Today I’ll be providing additional information about High Frequency (HF) Passive RFID. 13.56 MHZ HF RFID (passive) has the following characteristics:

  • Read range: from approximately 1 inch to 3.28 ft.
  • Reads multiple tags simultaneously
  • Moderate memory: 256 to 16KB
  • Penetrates most materials well, including water and body tissue
  • Easily embedded in non-metallic items
  • Not as effective as LF RFID in the presence of metal
  • Not typically affected by electrical noise in an industrial environment
  • Orientation of tags influences communication range-optimum range requires reader and tag to be parallel

Typical HF RFID applications include:

Check back next week for part 3 when I take a closer look at Ultra-High Frequency (UHF) RFID.
