Understanding RFID Readability Range: How Far Can RFID Be Read?

Discover the factors affecting RFID readability range, from centimeters to over 100 meters based on tag type.

17 views

RFID tag readability range varies and can be a few centimeters to over 100 meters, depending on the type of RFID system—Passive RFID tags have a shorter range (up to 25 meters), while Active RFID tags can be read from 100 meters or more.

FAQs & Answers

  1. What factors affect RFID reading distance? The reading distance of RFID tags depends on the type of RFID system, tag power source, and environmental conditions.
  2. What is the difference between passive and active RFID tags? Passive RFID tags are powered by the reader and have a shorter range, while active RFID tags have their own power source and can be read from greater distances.
  3. Can RFID tags be read through obstacles? RFID tags can face challenges when reading through obstacles like metal and water, which can disrupt the signal.
  4. What are common applications of RFID technology? RFID technology is commonly used in supply chain management, inventory tracking, access control, and asset management.
