Generally it's the interchange fees that fund reward programs (charged between banks), not the merchant fee.

It generally depends on the contract the merchant has with payment provider:
- some have relatively high merchant fees to cover for interchange fees
- others (generally called IC+) have the merchant pay the IC fee plus some other (generally much smaller) fee to the payment provider
In both cases it's the merchant that ends up paying them. It's not a concidence that in Europe (where there are caps to IC fees) the fees that merchants pay are generally lower.
