Working Groups

To further enhance efforts to develop the IFX specification, the Forum established Working Groups to define the business requirements and develop content for the specification applicable to specific sectors of the industry and particular use cases. Working Groups are not permanent, though many are long-lived. Over the years, the IFX Forum has had a variety of working groups that developed domain-specific content in addition to general content applicable to a broad range of banking operations.

Currently active Working Groups include:

  • Liaison and Interoperability Working Group
  • ATM/POS Working Group
  • Open Banking APIs Working Group
  • BIAN Services Working Group

Architecture Committee

The Architecture Committee ensures that the family of IFX specifications is consistent, efficient and easy to implement. Working to coordinate the various industries affected by financial transactions, the Architecture Committee unites the myriad requirements to provide one common solution between and among various industries interacting in the financial environment. More specifically, the Architecture Committee:

  • Reviews new IFX Forum initiatives
  • Provides coordination between the IFX Forum’s Working Groups, which define inter-industry requirements
  • Maintains the most current version of the IFX specification
  • Ensures interoperability of new enhancements with the IFX specification
  • Enables IFX specification implementation into new industries

Working Groups Over Time

  • Electronic Bill Presentment & Payment WG (inactive)

These working groups, made up of subject matter experts in their domains, built the content that has stood the test of time — making the IFX Business Messaging Standard a premier standard for financial services messaging.

IFX Partners

Because it’s impossible for one standard to address all of the needs of the financial services industry, the IFX Forum has both formal Memoranda of Understanding (MoUs) and informal agreements with a variety of organizations to facilitate cooperative activities in the sector that serve the industry as a whole.

ISO 20022

IFX Forum, Inc. was a founding member of the ISTH workgroup in 2003 along with TWIST, SWIFT and OAGi, which resulted in the initial ISO 20022 specification.The stated goal of that group was to recommend a common core payment message and transaction that could be accepted into each of the standards.The IFX Forum implemented that payment kernel in its 2004 Version 1.6 release, the first organization to do so.

In 2014 the IFX Forum completed the ISO standalone remittances messages. In 2015 and 2016, in partnership with Nexo (now EPASOrg) we submitted a comprehensive set of messages targeting ATM/POS. Those submissions have subsequently become part of the ISO 20022 repository.

BIAN (Banking Industry Architecture Network)

IFX Forum and BIAN are leaders in standardization in the banking industry. Both organizations have strength and roots in Service Oriented Architecture. It’s no surprise, then, that we have many member companies in common. And in both formal and informal discussion with these members, we have found a strong desire to bring to market the fruits of efforts made in both standards.

The Memorandum of Understanding established between the two organizations was just the beginning!

Business Payments Coalition

The IFX Forum has also, by invitation, taken a leadership role in the Remittance Coalition launched by the U.S. Federal Reserve.


Representatives of the IFX Forum regularly attend and participate in meetings of these standards bodies, such as the ISO TC68 Plenary Sessions.
