I think a lot of people don't get yet why this will be different from what they have known as NFC so far. This will probably be the biggest thing since the introduction of the first iPhone.
The way it's going to work if they really partner with Visa: You register your credit card with your iPhone, and then you leave the card at home. When you want to pay something with your phone, you touch your phone to the NFC reader at the checkout. The amount to be paid is displayed on your phone. Then you authorize the payment with your fingerprint. The iPhone then communicates with Visa to get a one-time token for exactly the requested payment, and the token is restricted to the store. That token is then passed to the cashier via the NFC reader, and the store uses the token to get the money from Visa.
Advantage: You never give your credit card or your credit card number to anyone else. Nobody can use the token you provided for their own purchases, because it is limited to a store, to a certain amount and it expires quickly. Think about it: Your credit cards don't belong in other people's hands, they don't belong in your wallets, they belong in a safe place at home. All that people need to pull money off your account is written on the credit card in plain text! Identitity theft is one of the biggest problems credit card owners face nowadays. This will kill identity theft. It will probably even kill the plastic credit card in the long run.
So no, this has nothing to do with NFC like you know it so far. It has nothing to do with NFC credit cards, because all they do is transfer your credit card number to the store via the NFC reader, so it's a slightly faster replacement for swiping, but that's all. NFC on phones so far has been a pointless vanity feature.
So it's a bit silly to say "I don't care about NFC", because this has nothing to do with how NFC is used now. NFC is just a tool, and Apple+Visa might have found the perfect use for that tool.
