BROKER-MEDIATED PAYMENT SYSTEMS AND METHODS

In certain embodiments of systems and methods for conducting payment transactions between a payer and a payee, the payer selects one or more payment sources from various funding sources and accounts available to the payer, and instructs a payment broker's server to perform payment authorization and/or payment making, causing to be made, routing and/or clearing services on the payer's behalf. The payment broker's server notifies the payer and/or the payee of the payment authorization status and, if approved, instructs the funding source's server to cause the payment to be made to payer-selected or approved real account(s) of the payee, or otherwise to the payee, without divulging the payer-selected funding source(s) and payer-selected real account(s) of the payer to the payee's depository bank or financial institution and/or to the payee.
