MasterCard has made a big move into making NFC mobile payments a little more accessible today by releasing their NFC SDK, which just happens to support BlackBerry 7. RIM has definitely made their intentions towards NFC well-known, and it appears that MasterCard has taken notice. With the release of the SDK developers will not be able to make their custom apps that will be able to tie into the PayPass back-end.
MasterCard has also released thousands of PayPass Tap-and-Go terminals throughout the world in an effort to help drive mobile payments. If you are a developer that is looking at potentially incorporating NFC payments into your app you can download the SDK for free here.
