While I've been a proponent of sensible regulation, I'll admit that there's some reservations I've had about the subject. I found a blog recently that address at some of these concerns.
- What effect will debit interchange regulation and the other aspects of the Amendment have on consumers?
- How will it impact card issuers who are striving to build cardholder loyalty and regular usage of their payment products?

Limiting payment flexibility: In addition to mandating that the Federal Reserve regulate debit card interchange rates so that they are “reasonable and proportional”, the Amendment would also allow retailers to set minimum purchase amounts of up to $10 before accepting electronic payments.
The idea of reduced-payment-options-equals-more-choice is, of course, a contradiction of terms. If consumers start to find that they can’t use their credit card for small purchases at a convenience store or drug store, is that in their best interests? Effect on debit card rewards programs: if the model of regulated interchange in Australia is any indication, some card issuers may start to cut back on the generosity of their rewards programs if the Federal Reserve chooses to lower interchange rates. In fact, in Australia, there was an average decrease in rewards program earn velocities of 23%.
Introduction of annual fees: a related issue that may impact consumers is that some issuers may find that adding an annual fee to the debit card rewards programs is necessary. Again, in Australia, many issuers did just that and increased fees by as much as 47% to 77%.
Eventual impact on other electronic payment options? Regulating interchange on debit transactions now could mean that Congress will attempt to regulate interchange for credit-card transactions later. If that were to take hold, these same impacts could affect consumers for the general purpose credit cards and retail co-brand credit cards they earn rewards on today.
