Embodiments of the invention provide a method of processing payment authorization requests for payment transactions to be conducted via a data communications network on behalf of online merchants. The payment authorization requests are conducted as a result of orders by financial instrument holders via a plurality of different online merchant systems, each of said online merchants having an online merchant identity. The method is conducted by a trusted central intermediary system which is configured to transmit payment authorization requests to each of a plurality of different online merchant Internet Payment Service Provider (IPSP) systems. In some embodiments, a user may select a payment method on a per transaction basis, while removing the requirement for the user to provide payment details to individual online merchant systems or to their merchant IPSP systems by having the user submit their respective payment details to a separate, trusted entity. |
