In an upcoming April 2009 initiative, the MasterCard Acquirer Access fee that is currently in place and being billed at a pass through cost of $0.005 per authorization is being eliminated and replaced with Network Access and Brand Usage (NABU) fee which will be billed at a pass through cost of $0.0185 per item.   This MasterCard change will greatly impact all merchants, especially those with small transaction sales.  Merchants should be prepared for this major change starting with April 2009 transaction activity.  Merchants should guard against providers that may try to apply these MC item fees to their Visa or Discover sales.
