How are RFID Tags Powered?

In this video, Colynn Black, RFID Business Development Director at Metalcraft, explains how passive RFID tags harness power to transmit signals. He breaks down the science of radio waves and introduces Decibel Milliwatts (DBM), a unit used to measure the intensity of radio frequencies relative to power. DBM is essential for understanding how RFID tags are powered through invisible radio waves. Colynn also explains the logarithmic scale used in DBM measurements, which differs from linear measurements. Watch the video to learn more about the fascinating process behind powering RFID tags.
