Trillcode
From Just Solve the File Format Problem
Trillcode is a 2-D bar code symbology intended for use with mobile phones. As with a number of the others, it has various marketing claims being bandied about purporting it to be uniquely good at various things, though some of them are things that some other symbologies also claim to be uniquely good at, including the ability to embed logos or other images inside the code to make it more aesthetic and marketing-friendly, and to "connect to the physical world", whatever that means.
