The acronym RFID (Radio Frequency Identification) describes
networked devices that contain microcomputers but are not thought of as
computing devices, such as refrigerators, automobile components, light
bulbs, and industrial control devices. RFIDs are battery-powered sensors that gather and transmit data to a reading device. Some sensor based technologies are scanning electron microscopes, LiDAR,radar, GPS, x-ray, sonar, infrared and seismic.
