Following Visa and MasterCard network fees for merchants, Discover is implementing a new Network Authorization Fee effective October 18, 2013. Each authorization request sent to the Discover Network will be assessed a fee of $0.0025. As part of their merchant agreement terms and conditions, most merchants will pay this fee as a separate line item on their merchant statements. Exceptions might be merchants that have some type of bundled pricing, in which case the overall bundled pricing may increase.
