Abstract: An online machine data collection and archiving process generates a machine data profile of a customer computer accessing a transaction form of a merchant web site and links the machine data profile and a transaction record with customer identifying information using a unique transaction identification string. The process preferably captures parameters typically communicated as a part of web accesses, such as an IP address, an HTTP header, and cookie information. The process additionally causes the customer computer to process self-identification routines by processing coding within the merchant transaction form, the self-identification routines yielding further profile parameters. The process further includes a routine for bypassing an intervening proxy to the merchant web site to reveal the true IP address of the customer computer.

Abstract: A method for processing a check transaction includes receiving transaction information that is transmitted by a terminal; determining eligibility of the transaction for payment via a bank account; providing an electronic authorization response that is transmitted to the terminal, the authorization response including a unique transaction identifier if the transaction is eligible for payment via the bank account; and receiving an electronic response packet that is transmitted by the terminal if the transaction is eligible for payment via the bank account, the response packet including the unique transaction identifier and a transaction decision regarding payment via the bank account.
