OTI COPNI wave - mobile NFC plug-in module

OTI has demonstrated impressive out-of-the box thinking with this NFC plug-in module for mobile devices. Basically, if your phone has an audio stereo jack, you can have mobile NFC.

Now the only questions are: which mobile OSes will OTI support, and will the API be open?

If only a few mobile OSes are supported within the first year (or two), then the API had better be open... A closed API would mean that freelance/community developers won't be able to fill the software gap for this device and some will opt for creating competing - and most likely open-source - solutions. This has already happened with mobile phones. Furthermore, integrated chips containing NFC controller+secure element are becoming readily available, as are NFC software libraries, so the entry threshold to the market is clearly not high.
