While prevalent in Asia, especially in Japan where 76% of the population is familiar with camera‐phone based barcode scanning 2D bar-coding has been slow to take off in the US, largely due to the major carriers failing to agree on which standards to support. At last there is an indication that the mobile industry is close to reaching agreement. The CTIA Wireless Internet Caucus Code Scan Action Team (CCSAT) – has launched a white paper on Camera‐phone Barcode Scanning
The technical building blocks described in the paper are intended to kick‐start the market. In the near term, an effective 2D barcode service will requires coordination among code publishers, technology service providers and the carriers,
The CCSAT group has agreed to help provide standardized and reliable 2D barcode services in the United States. It has agreed to coordinate the creation of a Central Registry and Clearing House, the adoption of initial code symbologies, and rules governing the use of a Service Mark.
The two initial codes selected are the proprietary code, EZ Code and Data Matrix, an ISO supported standard code.
2D bar-code readers from companies such as Scanlife have started to become popular, on the iPhone
2D scanning is one of several initiatives to link the physical to the digital via the camera in smartphones - other technologies to watch include - image recognition from companies such as SnapTell, Mobiglyphs and other advertising enhancing services such as ShopText and SNIPP
