It's complicated because it pushes fees onto the poor, who can least afford it.

Poor people only have debit cards, which have high fees.

Rich people use credit cards, which have low fees.

It would yet again be another situation where the poor pay more than the rich. Which is very often.

My understanding was that debit cards typically have lower fees than credit cards (except for small-value transactions).
