On November 12, 2009, the CheckImage Collaborative announced the creation of an enhanced universal companion document (UCD) for X9.100-187-2008. The UCD was developed by the CheckImage Collaborative's image quality work group with input from a wide range of financial institutions as well as major image exchange providers. X9.100-187-2008 is the successor of DSTU X9.37-2003. This standard is interoperable with DSTU X9.37-2003 and will ultimately replace the DSTU as the base standard for image exchange within the US payments system. The UCD will further enhance the flexibility and interoperability benefits of the X9.100-187-2008 standard. Currently, each image provider is required to develop its own unique companion document to implement the standard for its service offerings. By replacing this wide spectrum of differing documents, with one universal document, the UCD streamlines process and makes interoperability between various network providers significantly easier and more efficient. Any unique functions a provider might offer are included in the UCD as exceptions. Endpoint Exchange, SVPCO and Viewpointe have announced plans to implement the UCD by the end of 2010. The Federal Reserve Banks have not yet established a production date for the UCD but plan to monitor customer test results and industry adoption to ensure all participants are prepared for live implementation.
