Abstract: A computer implemented method for on-line purchasing via the global Internet. At a node connected to the Internet, customer data usable to automatically complete an on-line purchase by the customer of an item from a seller is received and stored. From a server, via the Internet, information is published to a computer of the customer, from the seller, with respect to an item, including metadata for use in associating said customer data with a customer action to purchase said item. A purchase indication is received from the customer computer, including at least a portion of said metadata for use in associating a customer purchase action with the item and metadata for use in associating said customer data with said transaction. In response to receiving said metadata for use in associating a customer purchase action with the item, the purchase is automatically completed by processing said metadata associating said customer data.
