Kart Saver, which marketed an electronic cart retention system five years ago, has invented what they are marketing as the "Audio Marketing System." The system utilizes an infrared transmitter mounted on the front of the shopping cart, which transmits a signal to speakers located on the retailers' shelves.
The electronic system automatically recognizes where the shopping cart is and activates the speaker located at the head of each aisle, as the cart passes by, giving the customer a 3-5 second promotional message that has been selected by the retailer or its suppliers.
Several different digital messages can be downloaded, via the Internet, and programmed into the same speaker, giving the customer various promotional advertisements from different suppliers.
Kart Saver is in the final stages of development for this product, and is now seeking funds to market the Audio Marketing System and complete the manufacturing process.
