Abstract
Containers for holding goods are provided with a relay conductive structure for relaying RFID tags signals from one side of the container to another. The conductive structure includes a first antenna on the first side of the container, a second antenna on a second side of the container and a transmission line connecting the antennas. When the containers are arranged in a stack, the relay of RFID signals past each row of containers enables the interrogation toward the rear of the stack without disassembling the stack of containers.
