NFC Talk application demonstrates connection initiation by tapping devices together or by searching for nearby devices over Bluetooth, using the Windows Phone 8 Proximity API, the Windows.Networking.Proximity.PeerFinder and related classes.

The example has been developed with XAML for Windows Phone devices and tested to work on Lumia devices with Windows Phone 8.

This example application is hosted in GitHub: https://github.com/Microsoft/nfc-talk
