hello, I've been looking for a way to turn on nfc card emulation on the nexus s and I came across the following recent blog post: http://mobisocial.stanford.edu/news/2011/01/nfc-on-android-for-social-applications/
They found some nfc p2p code that got removed from Gingerbread and they used it to develop some nfc applications. I didn't have time to analyse their work but I assume that it might be helpful for the rest of you. best regards aleks On 28 Jan., 06:25, nemik <[email protected]> wrote: > mtk, very cool!
