What Does Active Radio Frequency Identification (Active RFID) Mean?
Active radio frequency identification (RFID) is a wireless, automatic identification method, which uses self-powered tags to broadcast information about its identity and location. The battery powers the RFID circuitry and enables the active RFID tag to transmit identifying information, either by continuously beaconing to a tag reader, or when prompted to do so by a reader.
Techopedia Explains Active Radio Frequency Identification (Active RFID)
An active RFID can be programmed to send a signal on demand, or transmit at set intervals. The tags can also be activated to start transmitting at certain locations, or when a change in a sensed parameter is detected. The change could be in temperature, humidity or movement.
