Do RFID Tags Have a Battery? Understanding Passive vs Active RFID

Learn about battery usage in RFID tags, including the differences between passive and active RFID technology.

936 views

RFID tags can be either passive or active. Passive RFID tags do not have a battery; they are powered by the electromagnetic energy transmitted from the RFID reader. Active RFID tags, on the other hand, have their own battery, which enables them to transmit signals over longer distances and store more information.

FAQs & Answers

  1. What are passive RFID tags? Passive RFID tags do not have a battery and are powered by electromagnetic energy from the RFID reader.
  2. How do active RFID tags work? Active RFID tags contain a built-in battery, allowing them to transmit signals over longer distances and store more information.
  3. What is the main difference between passive and active RFID? The main difference is that passive RFID tags rely on energy from the reader while active tags have their own power source.
  4. What are typical applications for RFID technology? RFID technology is used in inventory management, asset tracking, and supply chain operations, among other applications.
