How RFID Technology Works Without Power: Passive Tag Explained

Discover how RFID tags operate without internal power, using energy from readers for efficient data transmission.

43 views

RFID tags work without power through passive technology. They use energy from nearby RFID readers. The reader emits radio waves that power the tag, allowing it to transmit data back to the reader. This interaction enables scanning items effortlessly without any internal power source, making RFID tags efficient and cost-effective.

FAQs & Answers

  1. What are the advantages of passive RFID tags? Passive RFID tags are cost-effective and do not require batteries, making them lighter and easier to integrate into various applications.
  2. Can RFID work over long distances? Yes, RFID can work over varying distances, though passive tags typically have a range of a few centimeters to several meters, depending on the reader's power.
  3. What is the difference between passive and active RFID tags? Passive RFID tags rely on energy from RFID readers to operate, while active tags have their own power source, allowing for longer range and additional features.
