Abstract: A third party e-commerce transaction is performed as an inline frame within a webpage. A user of the webpage may thus purchase a product or service from a trusted hosting entity, even though a different third party vendor processes the user's payment information and ships the product (and/or provides the service). Webpages may thus offer more third party products and services without incurring warehousing and payment processing burdens. The purchase transaction occurs entirely within the hosting entity's webpage, perhaps even without revealing the third party vendor.
