Dues & assessments
On a statement: DUES & ASSESSMENTS
A small percentage the card brands themselves (Visa, Mastercard, Discover) charge on every transaction, separate from the interchange that goes to the issuing bank. It is published, fixed and identical on every processor.
What a fair version looks like
About 0.13%–0.14% of volume per brand. On $82,000 a month that's roughly $100–$115.
What 321 Swipe would do
We verify the percentage matches the published rate — a padded assessment line is a classic place to hide a few basis points.
