A user-friendly process and fail safe system instantaneously identifies, locates, and help retrieve products and their contents in drawers, shelves, rooms, offices, stores, warehouses, etc. The efficient process and economical system is particularly useful to quickly and accurately identify, locate and help retrieve: computer discs, compact discs, software diskettes, video tapes, audio tapes, and their cases; books; files; boxes, cartons, storage bins, and other containers. In the reliable process and low power system, an electrically conductive label is placed on each product. Each label is easily coded to uniquely specify the product or its contents and storage location. Light emitting diodes (LEDs) or other visual, audible or mechanical signaling devices are positioned in proximity to the stored products and are in electrical contact with the labels on the products, as well as with a central processing unit (CPU) or other equipment used to specify and select the product. When a product is to be retrieved, the CPU or other equipment shuts off the LEDs or other visual or audible signal devices positioned in proximity to all the products not desired, leaving only the desired or failed items for easy identification and retrieval.
