ShotCode's software

The software used to read a ShotCode captured by a mobile camera is called ‘ShotReader’. It is lightweight and is only around 17kB. It ‘reads’ the camera’s picture of a ShotCode in real time and prompts the browsers to navigate to a particular site. The last website update was from 2007, suggesting that updates for phones based on Android and iPhone will not be available.
