Abstract: The Personal Shopping Buddy Shopping Cart Device provides a collapsible shopping cart equipped with state-of-the-art on-board electronics, configured to the needs of the individual user, and capable of digitally linking to the store's database to keep tabs on every item purchased as well as other information. Upon entering the store, the Personal Shopping Buddy automatically links to the store's database and proceeds to download the latest information. Every time the user takes an item from of the shelves, a built-in laser-scanner reads the product's UPC barcode as it is placed into the cart, allowing the system to keep a tab of precisely how much the user spends and exactly what items they are purchasing. The digital LED readout, located on the handle of the cart facing the user, clearly displays the current item count, total price, tax included, as well as other information.
