Hey, go and check the new documentation published this week on Nokia Lumia Developer's Library.

New section Proximity and Near Field Communication.
  • New article Using NFC to exchange information. Describes how to exchange information over NFC between two devices, or between a device and a tag. These two slightly different use cases are both explained in this article because on Windows Phone 8 they are implemented using the same API and in a very similar way.
  • Renewed article Using NFC to establish a persistent connection (replaces “Opening Sockets using NFC” article). Describes how to implement a tap and connect experience, using a simple peer-to-peer chat application – NFC Talk – as an example.

Post possible comments here or by using the feedback buttons at the end of each page in the library.
