Nfc idea

[Gecko]

I'm using Bluetooth to sync time and some other data, with an Arduino device i have made. The Arduino also uses NFC tags so has a NFC reader. I have it all working but i'm thinking my phone can send information using NFC as well as receive it. So it should be possible to do away with the Bluetooth. 

It's a bit beyond me at the moment , as i can only build apps with App inventor, and the NFC functions only support reading and writing to tags.

With a quick google it looks like there are 3 modes, 

Reader/writer mode: (supported by app inventor)

Card emulation mode:

Peer-to-peer mode: 

Although i could just about, get away with card emulation mode. Peer-to-peer mode would be the best.

So is anybody working on anything like this, know of any good links, or is writing an extension.
