Patent attributes
A method, system, apparatus, and computer program for conducting a real-time payment transaction. The method includes receiving a request for payment from a creditor financial institution (FI), and forwarding it to a debtor (FI). A payment transaction message is received from the debtor financial institution, specifying an amount of payment requested in the request, and is forwarded to the creditor FI such that the amount of payment is credited to an account in real-time. The debtor FI can request a return of the payment, in which case the creditor FI can comply therewith or refuse to return the payment. Also, an unsettled financial position of the debtor FI can be settled where that position does not exceed a combination of a pre-funded balance in a settlement account and a net debit cap value, and multiple settlements can be performed depending on a relationship between the position and combination.
