LOL. You all are delusional. The same people here that think everyone is going to use an iphone to pay for stuff are the same people that claim nobody ever upgrades the ram in their mac mini. Most people don't even know what it is. I'm pretty sure that retailers don't care about the few hundred people that use an iphone 6. They stand to make way more money with CurrentC even though its a horrible system. I'll stick with credit cards thank you. If someone charges up my card I simply call my card company and refute the charge. Done. Never going to give them my social and bank info, no way in hell. The way I see it they will both fail. Also, apple and google can't deny their app, its illegal as it creates an unfair market and when your company is richer than most countries that matters.
I think the retailers care very much or they wouldn't have moved so quickly to disable the capability.
