What merchant would sign up for that?
+1 -- if anything, the trend has been for quicker payouts and fewer holdbacks.
Merchants want zero fees, and instant payout (like cash), but "wait a minute" you might say. Don't businesses pay taxes, and how do you think those tax dollars are spent (in a non-gov't shutdown state)? Partially keeping the dollar bill presses running.
Herein lies the problem. Cash is a government-run operation, and credit card networks are privately owned. We forget that our cash system doesn't run itself and isn't free to operate, so we take cash for granted, and undervalue or ignore the "interchange" fees.
By changing their perspective, merchants might see that zero fees is unrealistic. It's an unfortunate(?) consequence of leaving the bartering days behind, and joining a money economy.
