Illinois Takes a Swipe at Interchange Fees—and Misses

Governments charge a fee for almost everything. When private companies do it, some legislators reach for a ban.

The argument in four steps

  1. Illinois banned card fees on the sales tax portion of a transaction.
  2. A federal court has already blocked it, since federal law lets banks charge those fees.
  3. Even if it stood, merchants would rebuild their payment systems to save a fraction of a per cent.
  4. The relief small businesses actually want is available by other means, and cheaper.

Terms in this piece

Interchange fee
What a merchant’s bank pays the cardholder’s bank to process a card payment. Usually a small percentage of the sale, plus a flat charge.
Price ceiling
A legal maximum set below the market price. The usual result is a shortage or a workaround rather than the saving that was intended.
Vendor discount
Letting a merchant keep a slice of the sales tax he collects, as payment for the work of collecting it on the state’s behalf.

“Swipe fee prohibitions play well with the public.”
