Abstract: A mobile device is provided with an information extracting application in response to a message received from the mobile device while located within retail establishment. Information that is then extracted by the mobile device from an information carrying indicia via use of the information extracting application is received from the mobile device and used to cause a display on the mobile device of a first web/wireless access protocal (“WAP”) page having information related to a product, wherein the first web/WAP page includes a link activatable while the mobile device is located within the retail establishment to initiate a purchase of the product. In response to activation of the link, the mobile device is caused to display at least a second web/WAP page to allow a user to specify a payment method to be used to purchase the product to specify a method by which the product is to be checked out/picked up/delivered to the user.

Abstract: A mobile device, such as a cellular telephone, is used to extract information from an information carrying indicia, such as a barcode. The information extracted from the information carrying indicia is then used to redirect a browser of the mobile device to a first web/WAP page having information related to a product, the first web/WAP page having a link that is activatable to allow for the purchase of the product. In response to activation of the link, the mobile device is caused to display a second web/WAP page that provides a means for the user to specify a method for paying for the product, such as by using an e-commerce like wallet, via a customer-service representative, etc., and a third web/WAP page that provides a means for the user to specify a method by which the product is to be delivered to the user, such as at home, in-store, at an in-car pickup facility etc.
