Open Financial Exchange: W3C proposed recommendation prepared by consortium led by Microsoft

Open Financial Exchange (OFX) is a unified specification for the electronic exchange of financial data between financial institutions, businesses, and consumers on the Internet.

Open Financial Exchange, a unified technical specification (Microsoft, Intuit, Checkfree) that uses open standards for data formatting (SGML), connectivity (TCP/IP and HTTP), and security (SSL). OFX transports financial information over the Internet, enabling privacy and message integrity, but lacks authentication and authorization capabilities.

A specification for bill presentment. It defines two fundamental capabilities for billing: communication of sign-up information from consolidator to biller, and communication of bill summary information from biller to consolidator. OFX does not define standards for the look of a bill. It merely provides a control channel for information about the bills.
