ShotCode is a circular barcode created by OP3. It uses a dartboard-like circle, with a bulls eye in the centre and datacircles surrounding it. The technology reads databits from these datacircles by measuring the angle and distance from the bulls eye for each.
ShotCodes are designed to be read with a regular camera (including those found on mobile phones and webcams) without the need to purchase other specialised hardware. Because of the circular design, it is also possible for software to detect the angle from which the barcode is read. ShotCodes differ from matrix barcodes in that they do not store regular data - rather, they store an encoded URL which the reading device can connect to in order to download said data.
