Embodiments of the invention include a method and system for effectuating
an electronic payment between a payor and a payee using an Electronic
Funds Transfer (EFT) network. The method is implemented by a system
having multiple processors. The payor may hold a payor account at a payor
institution and the payee may have a payee account at a payee
institution. The method includes generating a payment authorization
identifying the payee institution, the payee account, and an amount of
the payment and transmitting the payment authorization to the payor
institution. The method further includes debiting the payor account by
the amount of the payment; transmitting from the payor institution to the
payee institution though the EFT network an EFT credit message
representing a credit in the amount of the payment; and crediting the
payee account in the amount of the payment in response to the receipt of
the EFT credit message.
