For merchants processing with Connected Pay's interchange plus pricing, in general their rates will not be affected. Connected Pay's merchant base interchange fees were unchanged from the October 2009 rates.
Interchange Rates:
Visa - http://usa.visa.com/merchants/operations/interchange_rates.html
MasterCard - http://www.mastercard.com/us/merchant/support/interchange_rates.html
Many card providers offering a tiered structure (Qualified, Mid Qualified, Non Qualified) use the card association adjustment to increase possessing fees. Merchants with a tiered pricing structure should consider negotiating with their current processor to get to an interchange plus structure, such as the one Connected Pay offers.
