Abstract
A radio frequency identification (RFID) reader is disclosed that allows for selective deep scans of RFID tags. The RFID reader may include a motion detection sensor, a radio frequency transceiver configured to transmit RF energy at first and second frequencies, and a processor. The processor may perform the following steps: (1) when motion is detected by the sensor, commanding the transceiver to transmit RF energy at the first RFID profile; and (2) when motion has not been detect for a predetermined time period, commanding the transceiver to transmit RF energy at the second RFID profile. A method for using the RFID reader to perform selective deep scanning is also disclosed.
