I can answer that.
In our case, Visa charges the acquirer the extra 20 basis points for the Infinite card. So I get charged all of that for every Infinite card transaction that is processed. As Jim has said, we then have to negotiate with our merchants. So we collect that premium charge from most merchants; some have contracts that don't enable me to pass on that charge, so I am absorbing that cost. I don't get anything extra but I still have to pay Visa that cost.
