tikitag, which was one of the new techs that we saw at CES, has changed their name to touchatag. More notably, touchatag now features the ability to read 2D barcodes (also known as QR Codes).
As a side note, we discovered this bit of news via Twitter (of all places) via one of the engineers that works at touchatag. As much as Twitter can seem to be somewhat of a novelty on the surface, it is obviously becoming more of an important tool in the arsenal of any professional that needs to network in any way.
