Not really. This "revolution" is quite simple to occur (but I'm not commenting on how easy it would be implemented). 4) How it works is once you turn NFC on, you scan the device of desire (eg vending machine). Now a page opens on your iPhone with the cost (eg $2.60), the details (Queen St, Gothan City, Coca Cola vending machine), your current balance of your sync'd iTunes account (eg $20) and also a button that says you agree with the purchase / cancel purchase. Once you hit "Agree", you need to enter your iTunes password. Now either the electronic money would automatically shift into the vending machine's balance - or - you need to swipe the phone to the NFC again for that to happen. Personally, I rather carry some cash (coins and a twenty), and my credit card, and have iTunes (only via prepaid card) for media for my device(s) .... than to displace my cash/credit card completely inplace for iTunes-NFC-device.
