> But how far does this go in explaining why merchants "choose" to participate in this program. The obvious answer would seem to be that they get no benefit from the system as it exists but have no real choice, but maybe there is a better answer?
The simple reason why issuers don’t make every card a signature rewards card is that merchants would revolt.
The interchange fee schedule[1] is fascinating. Dozens of categories of merchants with different rates. There is no technical reason for this. Fraud costs are borne by merchants and to some extent processors, but not the issuer banks that receive the interchange fee.
The fee schedule reflects a kind of battle for customers. It’s worth repeating that most of interchange for these higher end cards is passed back to the customer in the form of rewards. Essentially, merchants are willing to pay higher fees to support the cards that higher spending customers prefer.
But there is a limit. We can observe that not all merchants accept AmEx, which has some of the highest interchange rates. If every visa/MC card were a signature card, more merchants would push back.
