Stanford Researchers Using NFC In Nexus S For Social Applications

 A team of researchers from Stanford are using the NFC technology inside the Nexus S to utilize NFC technology in new and exciting ways by creating peer-to-peer (P2P). We've heard from Google that they are interested and working on NFC payment systems on several occasions, but the social aspect of NFC is something we haven't seen before.

Back when Gingerbread was announced, it was made clear that the Nexus S had an NFC chip which could both read and write, but that the software has so far only enabled the reading of NFC chips, with an update to fully enable read/write coming later. To get around this problem, the Stanford team dug deep into Gingerbread's coding and found that there was some support for NFC P2P mode already built in.

However, they still had a lot of work to do and in the end, had to create their own NFC api and custom ROM. They have already created apps such as a whiteboard, picture sharing service, poker game, and a secure authentication service.

They use NFC to send a URL to another device telling that device what application to use and which session to join. The transfer of files is not executed through the NFC connection, as it is too slow. Instead, they share a URL and then transfer occurs using HTTP. 

Check out the two videos below to see the type of work they are doing and how it works:

The team from Stanford hopes that the api Google is working on will support the same type of actions which they have been working on. For more detailed information on their work, head over to the source link at the bottom.
