Google Wallet is an experiment that is definitely worth looking into, where it has certainly grown by leaps and bounds since it was released a few months ago. At least it has sorted out its fair bit of aversion to credit card payments, not to mention bringing along a merry bunch of new users via the introduction of the Nexus 7 tablet by Google (manufactured by Asus, of course). It does seem as though Google wants to introduce a bunch of new changes with a new version of Google Wallet in the pipeline.
On the main Wallet page, we do see advertising of the new version that is on its way, where it delivers a link to a signup page, where you can place in your request for an invitation to the new Google Wallet. Most folks would figure out that the iPhone and other non-Android hardware, too, will also feature Google Wallet support, and this alone might mean some focus have shifted from NFC to other platforms, perhaps via QR codes and cameras, no?
