  • Active RFID tags have a transmitter and their own power source. Instead, they draw power from the reader, which sends out electromagnetic waves that induce a current in the tag's antenna.
  • Semi-passive tags use a battery to run the chip's circuitry, but communicate by drawing power from the reader.
  • Radio frequency identification (RFID) can operate in three frequency bands: 125 kHz to 134 kHz, 13.56 MHz, or 856 MHz to 960 MHz. Bluetooth is 2.4 GHz; NFC is 13.56 MHz; and LTE is between 600 MHz and 6 GHz.
