The new iPad will have cameras (front- and/or rear-facing), higher resolution (or not), it will be using carbon-fiber or still a unibody and it will support NFC or Near-Field-Communication. So the rumors go.
And NFC is also rumored to be part of the iPhone 5, in order to compete with Google’s Nexus S, which already supports it. NFC is considered one of the key elements of the final breakthrough of mobile payment, replacing credit card with smartphones.
But the much more interesting question is, if the next releases of Apple iOS HW really support NFC, what kind of applications will be bundled with it? Considering the past success of Apple being based on creating a complete environment for new products and features (iPod – iTunes, iPhone – AppStore) I doubt that NFC will be released without any application to make use of it. But will it be mobile payment, e.g. replacing the current partnership with Starbucks around mobile payment or will it be the a big bank or a credit card company that joins the launch? It could be like lining up of media companies and games developers with the launch of the iPod, iPhone and iPad.
