The presentation is a low-cost, two-way communication system and method for aid in locating an object, such as a container or a package and reporting the contents of the object to a site remote from the location of the object. In one embodiment, the system includes two modules. A remote module includes a directional antenna array mounted on the top of the module (i.e., in a remote site), a processor including a direction-finding software, and a display for pointing the direction of the container's location relative to the remote site. Additionally, a response module includes a transceiver mounted on or within the container, which only allows an unique digital waveform to pass through and to response to a search signal from the remote module by transmitting a direction signal. This direction signal then activates the display in the remote module to indicate the location of the container relative to the remote module. In one embodiment, the response module accesses a database of the container and sends out the container's information to the remote module upon a request.
