Here is a dump of what is on the tag after writing the Wifi Config to it in Android L.

We are using chariotsolutions nfc-tag plugin for PhoneGap which does have support for writing tags with different MIME types, so it should be easy enough to include this in the Control App. The problem is going to be the limited initial support for this feature in Android until more devices are upgraded to L.

Now just curious what this other data is that is being written to the tag. Having a look at the source code for the Android L Preview now.

Will update when I know more.

Yeah, not already using it. Also just realising how large the elechouse unit is. Not really anywhere I can think to embed the unit in my current design.

Will let you guys know if this goes anywhere though.

I am currently in the process of building a keyboard (an ergodox). It would be totally awesome to build in an NFC Reader that would do just that.

At the moment I have a Teensy 2.0 to run the thing. I will look into adding the nfc reader, I can't remember how many pins I am currently using on the teensy, so I may have to upgrade the board to a 3.0 or an arduino. I like the idea of making an NFC HID, this way the the password could be used in other applications as well.

Maybe even have a set of passwords on the ring, and hold down a certain ke y at the same time to select the password to input.

I guess if you are putting a group of passwords on it then you would want to encrypt them, and maybe get the keyboard to decrypt them.

It would be simple enough to add this to the NFC Ring Control App. The problem is that I believe that only Android L devices would be able to make sense of it.

I am currently running the Android L Preview on my Nexus 5.

It looks like it writes it as type application/vnd.wfa.wsc and the data includes both binary data and the SSID and password in ASCII. I guess that the binary data might be something like security protocol.

I will post the whole thing when I get home, and maybe see if I can find out more about it.
