It's no secret that Windows Phone 8 devices such as the Nokia Lumia 920 and HTC 8X will have NFC integration. We are now seeing that an NFC reader/writer app should be available for these Windows Phone 8 devices. The NFC Interactor was announced at the NFC Congress in Hagenberg last month and will feature not only tag analysis but also a flexible tag composer.
Not really sure what all is involved with a flexible tag composer but our guess is that you can create a NFC tag for... say... your contact information and share it with another NFC integrated phone/device. Much like we can do currently with a QR Tag or Microsoft Tag and our Bing Vision.
The potential for such a composer could see the ability to share documents, photos, videos, and other content from Windows Phone to Windows Phone. It's a little reminiscent of the days when we could share items via IR and beam things from phone to phone just a whole lot cooler.
The French website, Test-Mobile, spent a little time with the Lumia 920 and in the video (around 9:58) you can see some of the capabilities NFC will have and then catch a glimpse at the NFC Interactor listed in the 920's apps list.
Granted my French is slightly rusty but it's still impressive to see the potential NFC will have with the new Windows Phones such as the 8X and Lumia 920.
