Abstract
A technique for operating a Radio Frequency Identification, RFID, reader with motion detection includes detecting a motion in proximity to the RFID reader, and triggering the RFID reader to read any tags in proximity to the RFID reader in response to detecting a motion in proximity to the RFID reader. Detecting a motion can also generate a change in digital signage, or communicate information about read tags to a local area network. Operating this system only when motion is detected saves battery life.
