Abstract: A method, system, computer program product, and device for providing product information, such as, for example, product price comparison information, product reviews, retailer information, retailer reviews, and information about similar products, to a user utilizing a mobile data processing system is provided. In one embodiment, a user, using a product code reader, such as, for example, an RFID reader, reads a product code from a tag, such as, for example, an RFID tag, located proximate to a product. The product code information determined from the product code is transmitted to a server. The server receives the product code information and retrieves the product information from a database. The server then formats the product information into, for example, a web page, and transmits the web page back to the mobile data processing system which receives the web page and presents the web page to the user.

Abstract: A method, system, and computer program product for providing product information, such as, for example, product price comparison information, product reviews, retailer information, retailer reviews, and information about similar products, to a user utilizing a mobile data processing system, such as, for example, a personal digital assistant (PDA), is provided. In one embodiment, the user scans a product code, such as, for example, a Universal Product Code (UPC) bar code, corresponding to a product which may be located on the product or product packaging. The scanner is coupled to the mobile data processing system which transmits the product code information determined from the product code to a server. The server receives the product code information and retrieves product information from a database. The server then formats the product information into, for example, a web page, and transmits the web page back to the mobile data processing system which presents the web page to the user.
