  • IMAGE RECOGNITION IN PASSIVE RFID DEVICES
    Publication number: 20130049926
    Abstract: Passive RFID devices are disclosed that perform image recognition. The device includes an antenna, circuitry, and a camera. The antenna receives a radio frequency (RF) signal from a RFID reader. The circuitry stores image data for objects that is used for image recognition. To operate, the circuitry derives power from the RF signal. With the power derived from the RF signal, the camera captures an image. The circuitry then identifies an object in the captured image based on the image data for the objects, and outputs information for the identified object, such as to the RFID reader.
