We just received a letter from Chase Paymentech dated March 4th (today is March 14), that on April 1st, both MasterCard and Visa will be adjusting their merchant interchange fees and certain rates may increase. All we know now is certain merchant interchange rates will be “modified.”
This is the link that Chase Paymentech provided for Visa, but the new rates will not be posted until April 1, the day the new rates take effect.
As for MasterCard, try figuring out what this means from the link provided by Chase Paymentech.
