Academic economist Joshua Gans says it would be "blatantly anti-competitive," because one of the things that forces banks to provide technology people want (like Apple Pay) is pressure from rivals. He says "Put simply, what the banks are doing smells awful."
It's estimated the local banks collectively make $2 billion a year in revenue from interchange fees.
