NFC payments, what’s stopping them?

Quite simply put all that is needed for using your mobile phone to pay for goods in Australia is a sim card with a secure element.
Microsoft wallet on Windows Phone 8 is ready to go with Microsoft confirming it is supported in Australia.
The banks will have you believe that they need to do extensive testing and certification but in actual fact they need not have anything to do with NFC payments.
Google’s wallet also works but is not yet enabled for Australia, although can be with some modifications.
The fact that we don’t have NFC payments already is a real shame when hardware vendors are ready to go, Visa and Mastercard are ready to go, we just need that secure element.
