The rise of smartphones has created an interesting phenomenon: #computers communicating optically by scanning barcodes on each other's screens.

This has some interesting #infosec properties:

* Humans can see when communication happens and control which devices are communicating (by pointing them at each other).

* Only a few bytes of data can be exchanged. This limits attack surface: there's no room for a non-trivial attack payload.

* This requires line of sight. No attacks through walls.

Brilliant review of Vivaldi in Heise Online. It is in German, but you will see subtitles in English, if you prefer.

For those of you asking why to use Vivaldi, you may well find your answer here.
