A system for storing a plurality of tangible assets, the system having an RF component associable with a tangible asset, wherein the RF component has a unique identifier and is configured to receive a carrier signal and emit a modulated carrier signal, wherein modulation of the carrier signal is based on the unique identifier. The system also has an RF detection system having a plurality of RF coils, wherein each coil is arranged to emit a carrier signal and receive the modulated carrier signal emitted by the RF component, a processor in communication with each of the plurality of RF coils, wherein the processor is configured to poll the plurality of RF coils by selectively allowing current to flow through one or more of the plurality of RF coils at a time and identify the RF component based on modulation of the carrier signal.
