But which one ... ;-) I may check this again with a friend.

The new jabcode (color barcode) from Germany's Fraunhofer Institute
is pretty cool, because it stores much more data then traditional b / w
codes. And it can withstand jpeg artifacts when converted back to .png!

Paperkey is good, but seriously we should also research this topic
a bit, because it might come in handy. And it would be interesting
to see with what solutions people would come up.

On the other side i wish PGPfone would have been further developed.
I found it, way back then, pretty cool and super easy to use, compared
to PGP or GnuPG.
