ABSTRACT:
An RFID Probe comprises a pole with a plurality of sensors that indicate RF signal strength attached at regular intervals and marked to indicate distance from an end of the pole. A user employs the RFID Probe by placing the probe between densely packed materials, such as cases on a pallet, and exposing the RFID Probe and packaging to a signal from a RIFD transceiver. After exposing the RFID Probe to the RFID transceiver signal, the user removes the RFID Probe from the packed materials and observes the sensors on the probe. By noting the location on the probe of the sensors indicating low or no RF signal, the user can identify locations where RF signal strength is insufficient to activate an RFID tag.
