A new Apple patent (number 20100082447) for an "on-the-go shopping list" has appeared at the US Patent & Trademark Office. It relates generally to handheld electronic devices (think iPads and iPod touches) and, more particularly, to systems and methods for conducting shopping-related transactions with a handheld electronic device.

Systems and methods for providing shopping-related information to a consumer are provided. Embodiments of the system allow a consumer to create an electronic shopping list by scanning products. In some embodiments, shopping-related information may be obtained for items in the shopping list, such as pricing information, product quality, consumer ratings, and other information that may help a consumer to make an informed purchasing decision. Other embodiments allow a consumer to obtain and compare retail prices offered by several retailers for products in the shopping list. Still other embodiments provide a store-wide network that allows a shopper to scan items in the store, add the scanned items to a shopping list, and then check-out electronically. The inventors are Gloria Lin and Amir Mahmood aMikhak.
