Like I mentioned before, I don't completely understand all the tech involved (more on the BTC side than the NFC) but I think there's a serious opportunity here for someone.

More physicality would really be a benefit for BTC.  The ability to literally toss BTC onto a countertop in exchange for goods and services would accelerate adoption.  NFC could be used (it seems) to load, read and unload chits in a convenient way.

All that's really necessary, in my partially informed view, is a low-cost reader.  Something like a plastic mat with an NFC coil in it. 

The chits might also be made to restrict themselves to specific amounts of bitcoins, and broadcast a simple on/off signal to verify that they are loaded. (Example: a 5 BTC chit has a '5' engraved on the outside.  You put the chit on the mat and the cashier immediately sees whether the chit is full or empty.)  This way the chits can be traded back and forth as physical currency until someone needs to unload them for whatever reason.  Conceivably, the NFC could also power a color-change in the chit for visual inspection. 

Or something like that.  My point is that there seems to be some potential in NFC for bitcoins, and I wouldn't mind knowing that someone is working on it.
