Abstract
A method for recovering missed RFID tagged items in an RFID tunnel environment is disclosed. The method comprises using a dynamic RFID tunnel system comprised of a first RFID tunnel and a second RFID tunnel to inventory one or more containers of items having RFID tags. A first RFID read of the one or more containers is performed in the first RFID tunnel and compared to an expected containers' inventory stored in a database. If the comparison does not match, a second RFID read of the containers is performed in a second, subsequent RFID tunnel at a higher RFID read power and by moving the containers at a speed slower than a speed of movement of the containers into the first RFID tunnel. If a comparison of the second read to the expected containers' inventory still does not match, the containers may be recirculated through the tunnel system or may be diverted to an exceptions audit depending on how the system is configured.
